Case history: A 4-month-old male Shih Tzu dog (Case 1) and an 11-month-old female Devon Rex cat (Case 2) were referred to specialist veterinary hospitals for evaluation of right thoracic lameness and growth abnormality in the distal aspect of the forelimb. Clinical findings: Non-weight-bearing lameness and decreased range of motion were noted in the affected limbs of both cases. Case 1 had a plantigrade stance, and a cleft separation between the first and second digits extending upwards to the distal third of the antebrachium. There was no pain on palpation, and the affected limb was shorter than the contralateral. Radiographic examination revealed cleft separation between metacarpal bones I and II, and carpal bone fusion (I, II, III), and the distal radius ended freely and was attached to the first metacarpal bone. Case 2 had a small cleft medial to metacarpal III. The limb was consistently held in abduction and had marked carpal varus. The limb had never been used for weight bearing. Radiographic examination showed agenesis of metacarpal bone II and separation of metacarpals I and III. The radius and ulna were separated and the radial head did not articulate normally at the elbow, leading to marked elbow incongruity. Diagnosis: Ectrodactyly in both cases. Treatment and outcome: Amputation of the radius followed by ulnocarpal arthrodesis were performed in both cases. Follow-up evaluations up to 1 year (Case 1) and 10 weeks (Case 2) after surgery indicated satisfactory arthrodesis fusion, owner satisfaction, and a good clinical outcome. Clinical relevance: Ectrodactyly is a rare congenital deformity of the forelimb with a heterogeneous character, requiring an individualised treatment plan. These are the first cases reported in the literature of ectrodactyly in small animals that were treated successfully with ulnocarpal arthrodesis. This case series therefore provides evidence in support of this treatment option for this heterogeneous congenital deformity. [ABSTRACT FROM AUTHOR]

Identifying risk factors associated with the carriage of antimicrobial-resistant (AMR) bacteria in dogs is crucial to understanding their epidemiology and for developing and refining targeted control measures. However, relevant data is scattered and conflicting findings have been reported. This systematic review aimed to compile risk factors associated with the carriage of AMR-Enterobacterales in dogs worldwide and to identify relevant knowledge gaps for directing future research. A systematic review was conducted according to PRISMA guidelines, searching PubMed, CABi, and Scopus databases for studies reporting risk factors for acquiring AMR-Enterobacterales in dogs. After screening peer-reviewed, English-language studies by title/abstract, eligible studies were subjected to a full-text assessment, data extraction, risk-of-bias assessment, and qualitative synthesis. In the initial search, 774 articles were identified, including 274 duplicates. After screening by title/abstract, 77 articles were subjected to full-text review, from which 40 were eventually selected for data extraction, including 29 cross-sectional, six cohort, and five case-control studies. The most frequently investigated risk factors for AMR-Enterobacterales carriage in dogs were antimicrobial use (28 of 40), age (24), sex (22), hospitalization (19), and feeding raw diet (14). Of these, antimicrobial use was themost common risk factor significantly associated with AMR-Enterobacterales (19/28), followed by raw diet (9/14) and hospitalization (8/19). Our synthesis emphasized the importance of increasing awareness regarding the prudent use of critically important antimicrobials (CIAs), such as fluoroquinolones, in companion animal practices, strengthening infection prevention and control procedures in veterinary clinics and hospitals and educating caregivers about the potential risks of feeding raw diets in order to reduce the burden of AMR-bacteria in dogs.

Objective: This study aimed to investigate the presence of ESKAPE organisms on the hands of students working in the intensive care unit (ICU) at a veterinary academic hospital. Methods: A cross-sectional study was conducted among students working in an ICU at a veterinary academic hospital in South Africa. Students were sampled before the start of the ICU shift using a modified glove-juice method. Standard microbiological techniques and a series of polymerase chain reaction (PCR) assays were used to identify and characterize the bacteria. All the isolates were tested for resistance against a specific panel of antibiotics using the disk diffusion method. Proportions of bacterial species and their antimicrobial-susceptibility profiles were calculated. Results: At screening, all the veterinary students (n = 62) carried at least one of the ESKAPE organisms on their hands. Escherichia coli was the most isolated organism (76%, 47/62), followed by P. aeruginosa (48%, 30/62), A. baumannii (47%, 29/62), E. faecium (35%, 22/62), K. pneumoniae (27%, 17/62), and S. aureus (24%, 15/62). A reduced proportion of isolates were recovered from the samples, E. coli (26%, 12/47), E. faecium (23%, 5/22), P. aeruginosa (43%, 13/30), A. baumannii (24%,7/29), K. pneumoniae (41%, 7/17), and S. aureus (20%, 3/15). Most of the organisms showed a high proportion of resistance to at least one antibiotic. Multidrug resistance was reported among just over half (56%, 5/9) of E. coli, 40% (2/5) of E. faecium, 100% (13/13) of P. aeruginosa, and 33% (1/3) of S. aureus isolates. Conclusion: Students working in the ICU carry several organisms belonging to the ESKAPE group of organisms before contact with patients. Moreover, MDR resistance was common among this group of organisms. The findings of the present study underscore the importance of infection prevention and control (IPC) strategies to help reduce the likelihood of the spread of these organisms to personnel, owners, family members, and patients.

Pseudopregnancy (PSG) is one of the most common syndromes diagnosed after oestrous cycle in female dogs. We found a diagnosed prevalence of PSG at 30.81% among reproductive pathologies in bitch. Concentrated oestrous occurrences in spring and autumn influence PSG distribution. PSG onset is marked by behavioural changes, followed by physical signs (mammary enlargement and galactorrhea). The last oestrous‐PSG onset interval ranged from 1 to 6 months (median = 3.0 months) and the median for the interval spaying‐PSG onset was 7.0 days. Half of the cases were discharged after 16 days, surpassing recommended treatment periods for cabergoline (4–6 days) and metergoline (8 days). Although Elizabethan collars were recommended, actual compliance stood at two‐thirds of cases. Our study highlights the possible underestimation of the PSG prevalence, probably due to lack of identification of clinical signs by owners. Further research is warranted to better understand possible risk factors, preventive measures or therapeutic options. [ABSTRACT FROM AUTHOR]

Objectives: To report the incidence of feline hypoalbuminaemia and characterise the distribution of presenting disease categories and pathoaetiologies of hypoalbuminaemia in cats. The secondary aim was to evaluate the relationship between hypoalbuminaemia and clinical outcomes. Materials and Methods: Medical records of cats with hypoalbuminaemia (<28.0 g/L, reference interval: 28.0 to 39.0 g/L) presenting to a veterinary teaching hospital over 5 years were retrospectively reviewed. The severity of hypoalbuminaemia was further stratified into mild (24.0 to 27.9 g/L), moderate (20.0 to 23.9 g/L) and severe (≤19.9 g/L) groups. The median albumin and severity groups were compared between the determined disease categories, pathoaetiologies and clinical outcomes. Results: The incidence of hypoalbuminaemia was 32.7% (533/1632). Gastrointestinal disease was the most common disease category associated with hypoalbuminaemia [154/533 (28.9%)], of which, 49.4% (76/154) of cats had gastrointestinal neoplasia. Neoplastic [159/533 (29.8%)] and inflammatory conditions [158/533 (29.6%)] were common pathoaetiologies noted. Statistically significant differences in the serum albumin between individual disease and pathoaetiological categories were found. Cats with moderate to severe hypoalbuminaemia had a statistically significantly longer hospitalisation period, cost of treatment and increased odds of death (odds ratio 2.4, 95% confidence interval: 1.3 to 4.6 and odds ratio 3.2, 95% confidence interval: 1.5 to 6.6, respectively). Clinical Significance: The incidence of feline hypoalbuminaemia in our study surpasses previous canine reports. Our findings support albumin as a negative acute phase protein in cats, with hypoalbuminaemia frequently associated with inflammatory disease. Hypoalbuminaemia also features prominently in cats with gastrointestinal neoplasia, indicating careful appraisal of the presence of protein‐losing enteropathy is required in these cases. Finally, albumin is found to be a prognostic indicator in this study. [ABSTRACT FROM AUTHOR]

Objectives: Adiponectin plays an important role in carbohydrate and lipid metabolism. However, the evidence regarding the association between adiponectin and diabetes mellitus in obese dogs is sparse. The aim of this study is to investigate the associations of adiponectin with the risk of diabetes mellitus in obese dogs on the basis of a prospective cohort study. Materials and Methods: Serum adiponectin levels in obese dogs recruited from three small animal hospitals between 2015 and 2018 were measured by ELISA. Electronic health records were used to record the incidence of diabetes mellitus during follow‐up for 3 years. Results: A total of 862 dogs were included. Amongst the 862 dogs, 51 developed diabetes. Adiponectin levels were associated with diabetes mellitus after adjusting for sex, age, breed, exercise, body condition score, fasting plasma glucose, serum triglyceride and total cholesterol. When adjusting for sex, age, breed, exercise, body condition score, fasting plasma glucose, serum triglyceride and total cholesterol, the adjusted hazard ratios were 7.83 (95% confidence interval: 2.67 to 30.13) in the lowest adiponectin group and 1.96 (95% CI: 1.10 to 8.55) in the medium adiponectin group relative to that in the highest adiponectin group. The area under a curve of adiponectin's Receiver operating characteristic curve was 0.81 (95% CI: 0.76 to 0.86). Clinical Significance: Low adiponectin is associated with diabetes mellitus and has a high risk of incident diabetes mellitus, implying the potential of adiponectin as a predictive biomarker of diabetes mellitus in obese dogs.

Simple Summary: Australian wildlife is often harmed by human activities. Veterinary hospitals play a crucial role in caring for individual animals and contribute to the protection of vulnerable species and increased animal welfare. This study investigated the wildlife patients arriving at two Australian hospitals to better understand the typical wildlife patients that veterinary hospitals can expect to encounter. Birds are the most common wildlife patients, often admitted due to injuries from car accidents. The study found a high mortality rate after admission, especially for animals with trauma or disease, compared to orphaned animals. It can be concluded that there are a number of challenges in the rehabilitation of wildlife. These findings add to our understanding of the challenges of caring for and preserving Australia's unique wildlife. Human activities in Australia frequently harm wildlife in their natural environments. Veterinary hospitals play an important role in treating individual animals and safeguarding threatened species. The primary objective of this study was to investigate the demographic and clinical characteristics of wildlife patients admitted to veterinary hospitals in Australia. Data from two wildlife hospitals situated in the southeast region of Australia was used to analyse the characteristics of wildlife patients. Avian species constitute the predominant category of wildlife patients admitted to these hospitals (54% and 60%, respectively). However, a large seasonal variation was observed for all types of animals. Traumatic injuries represent the foremost cause for admission for all types of animals; however, reptiles (62%) and birds (56%) were overrepresented in the category. Car collisions emerging as the most frequently encountered source of trauma. Moreover, the study reveals a notable mortality rate in admitted patients, approximately 50%, with an unfavourable prognosis for patients admitted due to trauma or disease. In conclusion, wildlife rehabilitation clearly presents a number of challenges. We recommend limiting rehabilitation patients, especially orphans and those not needing veterinary care, to focus resources on animals in real need. This could improve care quality, conserve resources, and enhance survival and release rates. [ABSTRACT FROM AUTHOR]

Background: Extended-spectrum β-lactamase -producing Enterobacterales (ESBL-E) are important zoonotic pathogens that can cause serious clinical infections, also in horses. Preventing the spread of ESBL-E, especially in the equine hospital environment, is key to reducing the number of difficult-to-treat infections. Estimating the local prevalence of ESBL-E in horses is crucial to establish targeted infection control programs at equine hospitals. We conducted a prevalence and risk factor study in equine patients on admission to an equine teaching hospital in Finland through a rectal ESBL-E screening specimen of the horse and a questionnaire. Results: The prevalence of ESBL-E in admitted horses was 3% (5/161, 95% CI 1–7%); none of the tested factors remained statistically significant in multivariate analysis, although antimicrobial treatment within three months was borderline significant (p = 0.052). Extended-spectrum β-lactamase -producing Klebsiella pneumoniae ST6179:CTX-M-15 was detected in three horses using whole-genome sequencing, which in combination with patient records suggested nosocomial transmission. Escherichia coli isolates were ST1250:CTX-M-1 (n = 1), ST1079:CTX-M-1 (n = 1), and ST1245:CTX-M-14 (n = 1). Multiple virulence genes were detected in the ESBL-E isolates. In the ESBL-E positive horses enrolled in a one-year follow-up study, ESBL-E were unlikely to be isolated in rectal screening specimens after the initial positive specimen. Conclusions: The prevalence of ESBL-E in horses visiting a veterinary teaching hospital in Finland is low, indicating an overall low prevalence estimate in the country's equine population. No statistically significant risk factors were identified, likely due to the low number of cases. The duration of ESBL-E carriage is likely to be very short in horses. [ABSTRACT FROM AUTHOR]

Psittacosis, or parrot fever, is a zoonotic disease caused by Chlamydia species associated with birds. One of the causative agents of the disease is Chlamydia psittaci, which is commonly carried by psittacine and other bird species, can be highly pathogenic and virulent to humans. In Hong Kong, a city with high population density, psittacosis is a notifiable disease with over 60% of cases in the last decade resulting in hospitalization. However, the sources of transmission of C. psittaci and its prevalence in pet birds in Hong Kong are currently unknown. To evaluate the risks of psittacosis transmission through pet birds, we tested the presence of C. psittaci and determined its genotypes in samples obtained from 516 captive birds from households, pet shops, and a veterinary hospital in Hong Kong. Results revealed that five samples (0.97%), collected from budgerigars and cockatiels, were C. psittaci-positive, while four (80%) of them were obtained from pet shops. Our phylogenetic analysis revealed that all identified strains belonged to Genotype A and showed high similarity to other sequences of this genotype obtained from various geographical locations and host species, including mammals. Our findings provide evidence for the presence of Chlamydia psittaci and shed light on its sources in captive birds in Hong Kong. They highlight the potential zoonotic risks associated with this pathogen, which can affect both humans and wild birds. [ABSTRACT FROM AUTHOR]

Background: Environmental bacteria in animal healthcare facilities may constitute a risk for healthcare-associated infections (HAI). Knowledge of the bacterial microflora composition and factors influencing the environmental bacterial load can support tailored interventions to lower the risk for HAI. The aims of this study were to: (1) quantify and identify environmental bacteria in one operating room (OR) and one ultrasound room (UR) in a small animal hospital, (2) compare the bacterial load to threshold values suggested for use in human healthcare facilities, (3) characterise the genetic relationship between selected bacterial species to assess clonal dissemination, and (4) investigate factors associated with bacterial load during surgery. Settle plates were used for passive air sampling and dip slides for surface sampling. Bacteria were identified by Matrix Assisted Laser Desorption—Time Of Flight. Antimicrobial susceptibility was determined by broth microdilution. Single nucleotide polymorphism-analysis was performed to identify genetically related isolates. Linear regression was performed to analyse associations between observed explanatory factors and bacterial load. Results: The bacterial load on settle plates and dip slides were low both in the OR and the UR, most of the samples were below threshold values suggested for use in human healthcare facilities. All settle plates sampled during surgery were below the threshold values suggested for use in human clean surgical procedures. Staphylococcus spp. and Micrococcus spp. were the dominating species. There was no indication of clonal relationship among the sequenced isolates. Bacteria carrying genes conveying resistance to disinfectants were revealed. Air change and compliance with hygiene routines were sufficient in the OR. No other factors possibly associated with the bacterial load were identified. Conclusions: This study presents a generally low bacterial load in the studied OR and UR, indicating a low risk of transmission of infectious agents from the clinical environment. The results show that it is possible to achieve bacterial loads below threshold values suggested for use in human healthcare facilities in ORs in small animal hospitals and thus posing a reduced risk of HAI. Bacteria carrying genes conveying resistance to disinfectants indicates that resistant bacteria can persist in the clinical environment, with increased risk for HAI. [ABSTRACT FROM AUTHOR]

A fifteen-month-old Pembroke Welsh corgi with respiratory distress, exercise intolerance, and moderate regenerative anemia was referred to The Norwegian University of Life Sciences, Small Animal Hospital. Hematology revealed moderate regenerative anemia without evidence of hemolysis. Thoracic radiographs showed a generalized mixed interstitial to alveolar lung pattern and enlarged pulmonary arteries. Changes suggestive of moderate pulmonary hypertension were noted on echocardiography. Baermann fecal diagnostic flotation identified large numbers of Angiostrongylus vasorum larvae, and the AngioDetect serological antigen test was positive. The dog was treated with a two-week course with fenbendazole (51 mg/kg q24h po) and topical imidacloprid/moxidectin (250 mg/62.5 mg) and a one-week course with sildenafil (0.45 mg/kg q12h po). Complete clinical, clinicopathological and echocardiographic resolution was observed after only four weeks. Rapid improvement of echocardiographic abnormalities in cases with suspected pulmonary hypertension is not usually reported in cases with angiostrongylosis. Infection with A. vasorum should be considered in dogs with respiratory signs and bleeding tendencies, even in countries with no endemic history or reported cases. [ABSTRACT FROM AUTHOR]

Background: B. canis infections have been reported in many countries of the world. B. canis can cause infections both in dogs and human beings. It can be transmitted to human via laboratory accidents during handling and contact with sick dogs. is an infectious agent for humans and it is transmitted to humans by various ways including laboratory accidents and contact with sick dogs. Methods: In this study serum samples were collected by using stratified random sampling method from the Diyarbakır Metropolitan Municipality Animal Care and Rehabilitation Center, where approximately 600 dogs were housed. Result: Out of 83 samples, 9.6% and 26.5% of serum samples were found as positive by B.canis RSAT and B.canis ELISA, respectively. While 6% and 9.6% of the samples were positive by B. abortus S99 RSAT and B. abortus ELISA, respectively. Sensitivity and specificity of B. abortus S99 ELISA was 98% and 95.5%, respectively. On the other hand, sensitivity and specificity of B.canis M (-) ELISA was 96.6% and 94%. As a result, it was concluded that B. canis infection is common in dogs and this should be considered both for dogs and public health. Unfortunately, there is no standardized commercial serological test for diagnosis of B.canis and other rough Brucella species currently. This is the main reason that rough brucella infections might not represent the real B.canis infection situation. Therefore, most of the cases have the possibility of being undetected. For this reason it is utmost important that B.canis RSAT and ELISA can be used as routine tests in the hospitals and veterinary clinics in the serological diagnosis of brucellosis.

Hospital-Associated Infections (HAIs) are caused by microorganisms that are not present before patients are admitted to healthcare facilities, and usually have multidrug resistance profiles. There is ample information and active research in human medicine to create preventive and control measures, but there have been fewer efforts in animal medicine, and studies in only a few countries have been examining how this problem presents in veterinary hospitals. In Mexico, there have been no studies on the presence of multidrug-resistant bacteria associated with HAIs in veterinary medicine. Therefore, the surfaces of inanimate objects and equipment in a university veterinary hospital for small species were sampled to search for bacteria with the potential to cause HAIs. After isolation, molecular identification and multidrug resistance tests were carried out. One bacterial strain was found to be resistant to carbapenems, third-generation cephalosporines, and penicillin/β-lactamase inhibitors. Additionally, other susceptible bacterial genera were identified as potential nosocomial pathogens in humans and animals. The presence of multidrug-resistant bacteria was confirmed. Further studies should be conducted to determine the isolate's origin and its relationship with reported human clinical genotypes. This type of study highlights the importance of epidemiological surveillance and the need to not underestimate the potential risk posed by multidrug-resistant microorganisms. [ABSTRACT FROM AUTHOR]

Enterococcus spp. are isolated from infections of domestic animals and can present resistance to different antimicrobials. This study aimed to identify the main species of Enterococcus and determine the phenotypic resistance to antimicrobials of isolates of this bacterial genus obtained from dogs and cats admitted to a veterinary hospital in southern Brazil. A total of 57 Enterococcus spp. were isolated from different clinical samples (urine, feces, ears and skin) in domestic animals admitted to the hospital over a period of three years (2016 to 2019). MALDI-TOF results demonstrated the occurrence of Enterococcus faecium (39; 68.4%), Enterococcus faecalis (17; 29.8%) and Enterococcus avium (1; 1.8%). In an overall analysis, resistance was observed to the antimicrobials rifampicin (46; 80.7%), tetracycline and streptomycin (42; 73.7%), ampicillin and imipenem (41; 71.9%), erythromycin (39; 68.4%), gentamicin (38; 66.7%), ciprofloxacin (36; 63.2%), norfloxacin (32; 56.1%), nitrofurantoin (10; 17.5%) and chloramphenicol (9; 15.7%). None of the Enterococcus spp. showed resistance to vancomycin and linezolid. Multidrug resistance (MDR) was detected in 45 (78.9%) isolates. In conclusion, E. faecium and E. faecalis with MDR are frequent in infections of hospitalized dogs and cats from southern Brazil. [ABSTRACT FROM AUTHOR]

The present study was undertaken to evaluate the anaesthetic effect of propofol isoflurane and propofol sevoflurane in twelve dogs with history of chronic cough, dyspnoea, laboured breathing, nasal discharge, exercise intolerance which were presented to the Department of Surgery and Radiology, Mumbai Veterinary College and Bai Sakarbai Dinshaw Petit Hospital for Animals, Parel, Mumbai. These dogs were randomly divided into two equal groups. In both the groups dogs were premedicated with acepromazine (0.04 mg/kg b.wt.) intravenously, and atropine sulphate (0.04 mg/kg b.wt.) and dexamethasone sodium (0.025 mg/kg b.wt.) SC 10 min before induction of anaesthesia. In both the groups, anaesthesia was induced with propofol (5 mg/kg b.wt.) intravenously. In group I anaesthesia was maintained using 2.5% isoflurane and in group II, 2.5% sevoflurane along with oxygen at a flow rate ranging from 500 to 1200 mL/min. History, physiological parameters, anaesthetic parameters were recorded at different time intervals during the study period. The present study findings suggest that induction with propofol and maintenance with isoflurane and sevoflurane proved best anaesthetic technique for thoracoscopy in dogs. [ABSTRACT FROM AUTHOR]

This study was carried out to determine the prevalence, risk factors, haematological and biochemical changes associated with haemotropic Mycoplasma infection in dogs presented to the Veterinary Teaching Hospital, Federal University of Agriculture, Abeokuta (FUNAAB). A total of 70 dogs were examined; their ages, breeds and sexes were recorded. Blood samples were collected for haematological and biochemical analysis. Data was summarized as mean ± standard deviation. Association between risk factors and infection was determined using Chi Square while difference between mean values in infected and non-infected dogs was tested using student's t-test. The overall prevalence of 14 (20%) was recorded. The prevalence was slightly higher 9 (20.9%) in adult dogs, as well as in females 8 (22.2%%) and the breed Samoyed 2 (40.0%). The mean PCV in infected dogs was 33.4±7.60 while that of non-infected dogs was 35.1±9.21. There was no significant difference in the haematological values between infected and non-infected dogs. There were also no significant values in most of the biochemical parameters between infected and non-infected dogs, except for potassium which was 2.85±0.96 in infected and 3.97±0.58 in noninfected dogs; chlorine (81.93±16.82) and (98.95±11.82); glucose (87.91±25.82) and (115.33±32.21) as well as urea (21.45±10.84) and (14.83±4.01) in infected and non-infected dogs, respectively. However, in both cases, the leukocytes, neutrophils and lymphocytes count as well as urea concentration were higher than normal values. While only potassium and chlorine concentration were lower than normal in the infected dogs, when compared to those in the reference values. In conclusion, the prevalence of Mycoplasma infection was high in the study area. Dogs are at risk of infection by Mycoplasma organisms. Mycoplasma infection did not cause haematological and biochemical changes, but haematological parameters suggested chronic diseases other than mycoplasmosis. [ABSTRACT FROM AUTHOR]

A 12‐year‐old male domestic cat with multiple subcutaneous mast cell tumours (MCTs) presented with a 2‐week history of pruritus and raw/bleeding skin from self‐trauma at Kagoshima University Veterinary Teaching Hospital. Polymerase chain reaction (PCR) and histopathological analyses revealed intertumoral heterogeneity among tumour locations based on the mutation status of KIT. In addition, the expression pattern of KIT was characterized. After failed treatment with vinblastine (2.0–2.2 mg/m2, intravenous administration, two doses in total) or nimustine (25 mg/m2, intravenous administration, two doses in total), toceranib (2.2–2.6 mg/kg, orally administered, every other day) was administered to treat recurrent MCTs harbouring the KIT exon eight internal tandem duplication mutation, achieving a complete response. However, toceranib resistance developed 2 months after treatment initiation. Subsequent PCR analysis was conducted to identify the mutational status of KIT in each MCT and to detect the presence of secondary mutations associated with the acquisition of toceranib resistance. Secondary KIT mutations (c.998G>C and c.2383G>C), which were not initially detected in tumour cells at diagnosis, were identified after the development of resistance to toceranib. This indicates that the tumour cells in feline MCTs in the same case have diverse characteristics. Our findings encourage further investigation into the development of therapeutic strategies for feline MCTs, particularly focusing on the heterogeneous nature of KIT/KIT and overcoming acquired resistance to toceranib.

OBJECTIVE Comparing the utility of the anti-human serum amyloid A (SAA)-specific monoclonal and polyclonal antibodies assays (LZ-SAA) with the pure monoclonal anti-human antibody assays (VET-SAA) during clinical practice in primary care hospital populations by measuring SAA measurement in healthy and diseased domestic cats. ANIMALS 52 healthy and 185 diseased client-owned cats. METHODS SAA concentration was measured using different LZ-SAA and VET-SAA measurements for healthy and various diseased cats. Sensitivity, specificity, and accuracy were calculated for each disease. RESULTS VET-SAA has higher sensitivity than LZ-SAA for the most common diseases presenting to primary care veterinary hospitals, including chronic kidney disease, tumors, and gingivostomatitis. Our results reveal the capability of detecting low SAA concentrations in healthy and diseased cats using VET-SAA in contrast to LZ-SAA, which found elevations of SAA concentrations only in diseased cats. CLINICAL RELEVANCE Our findings indicate that switching to the new VET-SAA instead of the conventional LZ-SAA will likely enhance the diagnostic performance in primary care veterinary hospitals.

Antimicrobial resistance (AMR) is an emerging human and animal issue. The frequency of resistance to high importance antimicrobials, isolation of microbes of One Health importance and the nature and frequency of multi‐drug resistant (MDR) profiles in Australian small animal referral practice have not been described previously. Medical databases of two private small animal referral hospitals in Queensland, Australia were reviewed for culture and susceptibility (C&S) results from 1 January to 31 December 2020. Hospital site (H1 and H2), culture sample, C&S results and MDR were documented for samples from services operating at both locations. There were 631 microbial isolates and 386 susceptibility profiles from 438 samples. The predominant organism was Staphylococcus pseudintermedius at H1 (n = 95) and Escherichia coli at H2 (n = 23). The majority of samples were integumentary (H1 n = 216, H2 n = 75) or urogenital (H1 n = 74, H2 n = 70). MDR isolates were reported at both hospitals, and were significantly more likely at H1 (69/262, 26.3% vs. 12/121, 9.9%; P < 0.001). High levels of AMR including MDR profiles were reported at the two hospitals evaluated, but they had significantly different resistance patterns and microbial profiles. These results highlight the need to practice appropriate antimicrobial stewardship in veterinary medicine, and are supportive for individual hospital surveillance with antibiograms.

To examine whether increased systemic arterial blood pressure (ABP) and decreased heart rate (HR) under inhalant anesthesia were suggestive of the Cushing reflex (CR) in dogs with neurological diseases based on magnetic resonance imaging (MRI) findings. Retrospective case-control study. A sample of 137 client-owned dogs admitted to two veterinary teaching hospitals for diagnosis and patient care owing to suspected intracranial disease from 2005 to 2020. All dogs underwent general anesthesia for MRI of the brain. Based on MRI study reports, dogs were divided into three study groups: group A, dogs with suspected brain herniation; group B, dogs with an abnormal MRI finding but without suspicion of herniation; and group C, dogs with structurally unremarkable brains (control). Initial evaluation by an anesthesiologist resulted in 58 cases selected for further review based on suspicion of having intracranial hypertension, as indicated by ABP and HR changes under anesthesia. Anesthetic records were randomized and independently reviewed by three board-certified anesthesiologists blinded to MRI diagnosis who allocated each dog into one of three groups: 1) likely to have CR; 2) unlikely to have CR; or 3) insufficient data for determination. Of the 58 cases evaluated, nine were considered likely to have CR and 48 were considered unlikely to have CR. In one case, the anesthesiologists were unable to determine whether CR occurred. Of the nine dogs with likely CR, three had an MRI diagnosis of intracranial herniation. The remaining six dogs suspected of CR belonged to the normal brain group. The ABP and HR changes associated with CR are not reliably associated with brain herniation in dogs undergoing general anesthesia. [ABSTRACT FROM AUTHOR]

Purpose: The objectives of the present study are to determine the molecular prevalence of Leishmania spp. in the owned domestic cats in the Black Sea Region of Türkiye and analyze the associated risk factors in FeL. Methods: Conjunctival swabs (CS), blood, demographic, and clinical data were collected from 150 owned cats brought to the Veterinary Teaching Hospital during 2020–2022. Leishmania kinetoplast DNA (kDNA) from CS was screened by TaqMan Real-Time PCR (qPCR) with the genus-specific primers and a probe. Results: All qPCR positive products were also amplified and sequenced to identify Leishmania species by ITS1 primers. Molecular prevalence of L. infantum found as 12.6% (19/150) in the observed cats in the Black Sea Region of Türkiye. There was a significant difference (p < 0.05) between neutered and intact cats with regarding to L. infantum positivity. Intact cats found to be 0.368 times more prone to be L. infantum-positive (L+). Dermatological lesions were found the most common (26.3%) problems in the L + cats. The median leucocyte count was the only parameter that was found statistically (p < 0.05) lower in the L + group (6.60) than the negative group (L−) (8.96), when comparing the WBC, NEU/LYM, MONO/LYM, EOS/LYM and PLT/LYM values. Conclusion: This study presented the molecular occurrence of FeL in the Black Sea Region of Türkiye for the first time indicating that the carrier status of the cats makes them alternative reservoirs for possible zoonotic transmission of L. infantum in this zone.

During a 3‐year time period, a 15‐year‐old male castrated Terrier mix (dog 1) and a 6‐year‐old female spayed Labrador Retriever (dog 2) presented to the North Carolina State Veterinary Hospital with similar blood work abnormalities and no significant physical examination findings. A CBC, chemistry panel, and urinalysis performed on both dogs were relatively unremarkable, other than a marked increase in serum gamma‐glutamyltransferase (GGT) activity. Through imaging, both patients were diagnosed with a renal mass, and histopathology of both masses revealed a carcinoma. Immunohistochemical staining of the renal mass in both dog 1 and dog 2 were intensely positive for GGT. Dog 1 had the affected kidney removed, which normalized the GGT value. Dog 2 was euthanized, and metastasis to the lung was noted upon postmortem examination. There have been limited case studies documenting an elevation in serum GGT in dogs diagnosed with renal carcinoma. While renal carcinoma is uncommon in dogs, it is an important differential to keep in mind when there is a marked increase in serum GGT without accompanying increases in other measured liver enzymes. In addition, serum GGT can serve as a helpful biomarker for disease resolution and recurrence, as surgical removal of the renal mass (dog 1) led to the resolution of the elevated serum GGT. To our knowledge, this is the first report demonstrating IHC staining for GGT in a canine renal carcinoma. [ABSTRACT FROM AUTHOR]

Enucleation and exenteration are widely utilized ophthalmic procedures in veterinary field. Enucleation in camels is like other large animals, typically performed under the influence of heavy sedation and loco-regional analgesia. The aim of the current study was to introduce a new surgical approach to enucleate the eye of camels through supraorbital fossa approach. for that purpose, the technique was applied to seven camels referred to the King-fisal teaching veterinary hospital for unilateral enucleation. Assessment of applicability, safety and feasibility of this technique was done. All procedures were performed in the kush (sitting) position under the influence of heavy sedation with Xylazine HCl in combination with retrobulbar nerve block. A "C" shaped skin incision was made in the skin and fascia of the supraorbital fossa to enter the orbital cavity, after which the periorbital fat was gripped, dissected and removed. Bleeding controlled by electrocautery and visible large blood vessels were ligated. After ligation the optic nerve and ophthalmic blood vessels, the eyeball was dissected sharply and freed from the orbital bony attachment. Finally, the orbital fascia and skin were sutured with simple interrupted pattern separately. The approach proved successful in all camels, with the enucleation procedure being both feasible and easily performed. The mean surgical time was approximately 46.6±12.4 minutes. The minimal occurrence of short and long-term complications was encouraging, and the cosmetic outcomes were notably improved. The supraorbital approach is a safe and effective technique for camel ophthalmic surgery, showing advantages in exposure and minimal complications. Further research is needed for validation and broader clinical applications. [ABSTRACT FROM AUTHOR]

Background: Cats are hosts and reservoirs for many haemopathogens such as piroplasms, Rickettsia, hemotropic Mycoplasma, Bartonella, Ehrlichia, and Anaplasma, which are transmitted by various vector arthropods and some of which have a zoonotic concern. Although it is noteworthy that the rate of ownership of companion animals has increased in Türkiye in recent years and that cats account for a large proportion of these animals, there is limited research on the vector-borne infectious agents carried by them. The present study aimed to provide a comprehensive molecular epidemiological data and molecular characterization of feline vector-borne haemopathogens (FVBHs), including piroplasms, anaplasmataceae, rickettsias, haemoplasmas, and Bartonella species in Türkiye. In total, 250 feline blood samples were collected from client-owned cats (n = 203) and shelter cats (n = 47) brought to the Small Animal Hospital of Selcuk University, Veterinary Faculty. Results: Overall, 40 (16%) cats were found to be infected with at least one of the investigated haemopathogens and piroplasm, Mycoplasma spp. and Bartonella spp. prevalence was 1.6%, 11.2%, and 4.8%, respectively. No Anaplasma/Ehrlichia spp. and Rickettsia spp. DNA was detected in the investigated feline samples. Sequence analysis revealed that all four piroplasms belonged to Babesia ovis with a 97.93–99.82% nucleotide sequence identity to 18S rRNA gene sequences from Spain and Türkiye, while some sequenced hemoplasmas were Mycoplasma haemofelis (Mhf), Candidatus Mycoplasma haemominutum (CMhm) and Mycoplasma wenyonii, and Bartonella spp. were Bartonella henselae and Bartonella koehlerae species. Co-infections with Mycoplasma spp. and Bartonella spp. were also detected in 4 cats (1.6%) in this study, where single infections were predominant. Conclusion: This study provides valuable information on zoonotically important feline vector-borne hemopathogens in Türkiye, some of which have received attention under the One Health perspective, and is the first molecular epidemiological study to demonstrate the presence of Babesia ovis, the causative agent of ovine babesiosis, and Mycoplasma wenyonii DNA, the causative agent of bovine haemotropic mycoplasmosis, in cats. Further studies on the roles of such pathogens detected in unspecific hosts and the host specificity of the vectors that transmit them will contribute to the elucidation of this situation.

Inhalational anaesthetic agents are routinely used in veterinary anaesthesia practices, yet their consumption contributes significantly to greenhouse gas emissions and environmental impact. We conducted a 55-day observational study at a veterinary teaching hospital in Switzerland, monitoring isoflurane and sevoflurane consumption across small, equine and farm animal clinics and analysed the resulting environmental impact. Results revealed that in total, 9.36 L of isoflurane and 1.27 L of sevoflurane were used to anaesthetise 409 animals across 1,489 h. Consumption rates varied among species, with small and farm animals ranging between 8.7 and 13 mL/h, while equine anaesthesia exhibited a higher rate, 41.2 mL/h. Corresponding to 7.36 tonnes of carbon dioxide equivalent in total environmental emissions or between 2.4 and 31.3 kg of carbon dioxide equivalent per hour. Comparison to human anaesthesia settings showed comparable consumption rates to small animals, suggesting shared environmental implications, albeit on a smaller scale. This research highlights the importance of continued evaluation of veterinary anaesthesia practices to balance patient safety with environmental stewardship; potential mitigation strategies are explored and discussed.

Dermatophytic pseudomycetoma (DPM) is a rarely reported invasive fungal infection of humans and animals, especially cats. This study aimed to identify dermatophytes, breed associations, and the frequency of extracutaneous (EC) involvement in feline DPM. Electronic records and formalin-fixed paraffin-embedded tissue (FFPET) from 32 suspected DPM cases in 30 cats were retrieved from a diagnostic laboratory between 2018 and 2024. To confirm DPM and molecular identity, DNA was extracted from FFPET for ITS2 sequencing, and immunohistochemistry was performed on PCR-negative cases. All cases were confirmed as DPM. Microsporum canis was the only dermatophyte identified. The sensitivity and specificity of ITS2 sequencing for M. canis identification in FFPET were 22/32 (68.8%) and 21/22 (95.5%), respectively. Exotic (36.7%) and Persian (23.3%) but not British breeds (26.3%) were over-represented compared to feline admissions at an affiliated veterinary hospital (8.5%, p < 0.001; 3%, p < 0.001; 21.6%, p = 0.817, respectively). Five cases (16.7%) had EC lesions; two had intra-abdominal masses; two had oral cavity masses, including one which extended into the cranial vault; and one had superficial cervical lymph node invasion. Exotic and Persian breeds are over-represented for DPM and M. canis is the primary cause. EC lesions of DPM may occur more commonly than previously thought. [ABSTRACT FROM AUTHOR]

Summary: Internal bleeding and mucosal bleeding in hollow organs are uncommon conditions in equine medicine and endoscopy. Most of the time, they respond to treatment of the underlying primary condition. However, there are cases in which a rapid and effective control of blood loss is required and the animal is not suited for surgery or general anaesthesia. We report two cases referred to our Veterinary Teaching Hospital with signs of urinary disease and bladder haemorrhage identified by cystoscopy which were successfully managed with topical application of a haemostatic carboxymethyl‐starch powder. The product was applied directly on the bleeding mucosa after bladder emptying either under endoscopic guidance or blindly, through a urinary catheter. The application of the haemostatic powder appears to be easy to perform, safe and helpful in controlling mucosal bleeding in hollow organs in a short time, with no adverse reactions noticed. This approach should be considered in cases where mucosal bleeding can be identified by endoscopy and a prompt control of blood loss is required, also in the field. [ABSTRACT FROM AUTHOR]

The identification of local susceptibility patterns is important for the elaboration of effective local antimicrobial use guidelines and improvement in treatment outcomes. This retrospective study investigated the prevalence of microbial pathogens in dogs over a five-year period (2019–2023) and their antimicrobial resistance patterns with an emphasis on multidrug-resistant strains on the basis of 896 swab samples submitted to the microbiological laboratory at the University Veterinary Hospital, Stara Zagora, Bulgaria. A total of 1247 strains—1046 bacteria and 201 yeasts—were isolated. An increased proportion of Staphylococcus spp. as an agent of infections in dogs along with significant decrease in the share of Streptococcus spp. (from 16.2% in 2019 to 7.7% in 2023) was found. The occurrence of Staphylococcus spp. in otitis externa increased from 53.4% in 2019 to 84.5% in 2023 (p < 0.0001). The resistance of Staphylococcus spp. isolates to amoxicillin/clavulanic acid and cephalexin increased significantly in 2023 vs. 2022. At the same time, increased susceptibility to amikacin was observed in 2023 vs. 2019. For Enterobacteriaceae, significantly decreased resistance against amikacin and marbofloxacin was demonstrated in 2023 compared to 2019. Multidrug resistance (MDR) was present in 405 of 1046 bacterial isolates (38.7%). More than 50% of streptococci and pseudomonads were MDR. Of the MDR staphylococci, 41.7% were isolated from skin lesions and 28.3% were isolated from otitis. More than half of the strains resistant to seven, eight and nine groups of antimicrobial drugs (AMDs) were from wounds/abscesses. The results highlighted the importance of regular local monitoring of the spread of bacterial strains in veterinary clinics and their susceptibility to AMDs with regard to successful therapy outcomes and control on MDR spread.

Objectives: Studies in humans have demonstrated the role of Toxoplasma gondii, a protozoan parasite, in epileptic seizures. This study aimed to investigate the serological correlation between T. gondii and N. caninum and epilepsy in dogs. Materials and Methods: The medical record database of the Veterinary Teaching Hospital, University of Perugia, was searched for dogs serologically tested by IFAT for T. gondii and N. caninum and following specific inclusion criteria. Dogs were stratified by having a clinical diagnosis of epilepsy or suffering different conditions. Results: One‐hundred and twenty‐eight dogs were included, 64 with epilepsy and 64 without clinical signs of epilepsy. Seventeen of the 64 epileptic dogs (26.6%; 95% CI: 15.7% to 37.4%) and twenty‐one of the 64 non‐epileptic dogs (32.8%; 95% CI: 21.3% to 44.3%) tested positive for T. gondii. Eight of the epileptic dogs (12.5%; 95% CI: 4.4% to 20.6%) and three of the non‐epileptic dogs (4.7%; 95% CI: 0% to 9.9%) tested positive for N. caninum. There was no statistically significant difference in the rate of T. gondii or N. caninum seroreactivity between epileptic and non‐epileptic dogs. Clinical Significance: The results obtained do not seem to support the role of T. gondii and N. caninum as causative agents of dog epilepsy. [ABSTRACT FROM AUTHOR]

Malignant peripheral nerve sheath tumour is an uncommon tumour in cats. The current case report aims to present the diagnosis, treatment and histopathology of a malignant peripheral nerve sheath tumour that developed in the cerebellopontine angle region of a cat. A 4‐year‐old 4.2‐kg female calico cat was brought to the animal hospital with the complaints of loss of balance, leaning against the wall and behavioural changes. During the neurological examination, the patient was observed to have a right‐sided head tilt accompanied by ipsilateral ventral strabismus. On magnetic resonance imaging scan, a mass was identified at the right cerebellopontine angle. The surgical removal of the mass was carried out using a caudo‐tentorial approach. The histopathological analysis revealed the presence of a malignant peripheral nerve sheath tumour. This case report contributes to the existing knowledge in the field presenting the characteristics of a malignant peripheral nerve tumour that was not associated with any nerve in the cerebellopontine angle in a cat.

Multiple complications associated with dystocia are common outcomes of oxytocin abuse in managing bovine dystocia by farmers in rural settings. Most of these outcomes are either unreported or under-reported due to the eventual loss of both the dam and foetus. A 6-year-old White Fulani cow weighing 300 kg was presented at the Veterinary Teaching Hospital, University of Ibadan, Nigeria, with difficult labour noticed about 4 days before presentation. The owner had reportedly administered 40 IU of Oxytocin intramuscularly before bringing the cow to the clinic. The animal was multiparous and kept under an intensive management system with other cows at the owner's residence. On physical examination, the cow was weak, recumbent and bloated, with a prolapsed vagina. Clinical examination revealed evidence of hypocalcaemia and dehydration. There was no foetal presentation, and the cervix was tightly closed. The foetus, weighing 28 kg, was successfully delivered by Caesarean section. Post-surgery, the cow retained the placenta and was unable to stand for more than 12 hours. Despite intensive care, the animal died about 18 hours post-surgery. This article describes an emergency Caesarean section in a White Fulani cow that had been previously and unduly exposed to oxytocin resulting in multiple complications. [ABSTRACT FROM AUTHOR]

The authors report on the rare occurrence of dual synchronous primary brain tumors in a canine patient, successful treatment with radiation therapy, and medical therapy with patient stabilization for almost three years. A 12.5-year-old spayed mixed-breed female Labrador was referred to Purdue Veterinary Hospital to treat hyperadrenocorticism of suspected pituitary origin. During MRI imaging, the presence of two possible brain neoplasms was detected: a possible right olfactory bulb meningioma and a microadenoma of the pituitary gland. The patient was treated with a fractionated course of radiation in both tumors, 15 treatments of 3Gy, which limited the tumor growth. Mitotane therapy corrected the hormonal dysregulation. The dog had a normal life for nearly three years and recently passed. Cancer cells were not found at necropsy. No MEN1 germline mutations were identified in constitutional DNA (from blood) via high-coverage whole genome sequencing. [ABSTRACT FROM AUTHOR]

Background: Equine herpesvirus 4 (EHV-4) causes respiratory disease in horses, and the virus is considered endemic in the global equine population. However, outbreaks can occur when several horses are gathered in relation to shows, competitions, breeding units and at hospitals. In the spring year 2022, an EHV-4 outbreak occurred at the Large Animal Teaching Hospital, University of Copenhagen, Denmark. Nine horses were tested EHV-4 positive during the outbreak, which lasted approx. seven weeks. In addition, a tenth horse "Eq10" tested EHV-4 positive almost three weeks after the last of the outbreak horses tested positive. Detailed clinical registrations were obtained from all ten horses as well as their location and movement during hospitalization. Nasal swabs were obtained throughout the outbreak and tested by qPCR for EHV-4. Additionally, pre- and post-infection sera were tested for the presence of EHV-4 antibodies. Selected samples were characterized by partial and full genome sequencing. Results: The most common clinical signs of the EHV-4 infected horses during this outbreak were pyrexia, nasal discharge, mandibular lymphadenopathy and increased lung sounds upon auscultation. Based on the locations of the horses, EHV-4 detection and antibody responses the most likely "patient zero" was identified as being "Eq1". Partial genome sequencing revealed that Eq10 was infected by another wild type EHV-4 strain, suggesting that the hospital was able to eliminate the outbreak by testing and reinforcing biosecurity measures. The complete genome sequence of the outbreak strain was obtained and revealed a closer relation to Australian and Japanese EHV-4 strains rather than to other European EHV-4 strains, however, very limited sequence data are available from Europe. Conclusion: The study illustrated the transmission of EHV-4 within an equine facility/hospital and provided new insights into the viral shedding, antibody responses and clinical signs related to EHV-4 infections. Finally, sequencing proved a useful tool in understanding the transmission within the hospital, and in characterizing of the outbreak strain. [ABSTRACT FROM AUTHOR]

Caprine babesiosis is a tick borne haemoprotozoan infection less frequently reported from Kerala. In the present report, we document a confirmed case of Babesia motasi for the first time in the state. A Sirohi Kathiavari crossbred goat was presented to the University Veterinary Hospital (UVH), Kokkalai with symptoms of anorexia and pyrexia. On blood smear examination, large and small forms of Babesia organisms in Giemsa's stain could be detected. Complete blood count revealed hypochromic microcytic anaemia with thrombocytopenia. Molecular confirmation was done with polymerase chain reaction (PCR) targeting 18S rRNA gene. A 390 bp fragment was obtained and sequenced which was confirmed as Babesia motasi. Babesia ovis or Theileria spp., could not be detected by PCR. This study reports the molecular confirmation of two forms of B. motasi in a crossbred goat from Kerala. [ABSTRACT FROM AUTHOR]

On April 10, 2024, a stray dog was found in the city of Recife, Pernambuco, Brazil, with an extremely distended abdomen. Initially, pregnancy was suspected, but a more detailed analysis revealed the presence of mucopurulent function in the vulva, raising the suspicion of Open Pyometra. The chain was taken to the Veterinary Hospital of the Federal Rural University of Pernambuco, where it underwent an imaging exam that confirmed the diagnosis of Open Pyometra. After confirmation, the animal was sent to the surgery team. Analgesia and anesthesia were administered under the supervision of an anesthesiologist, and the dog was subsequently prepared for surgical intervention. [ABSTRACT FROM AUTHOR]

Background: Traditionally, 6‐month courses of prednisolone are used to treat steroid‐responsive meningitis‐arteritis (SRMA), but this medication is associated with adverse effects that can lead to poor quality of life. Hypothesis/Objectives: Resolution of clinical signs and rate of relapse of SRMA would not be significantly different between a 6‐month prednisolone protocol and a 6‐week protocol. Animals: Forty‐four hospital cases from multiple referral centers in the United Kingdom (2015‐2019). Twenty of 44 were treated with the 6‐month protocol and 24/44 with the 6‐week protocol. Methods: Prospective, randomized trial with 12‐month follow‐up. The same prednisolone protocol reinitiated in the event of relapse. Analysis of relapses with binary logistic and Poisson regression modeling. Results: All cases responded to their treatment protocol. Relapses occurred in 6/20 (30%) of the 6‐month protocol and 9/24 (38%) of the 6‐week protocol. There was no statistical difference in the incidence risk of at least 1 relapse between the 2 groups (odds ratio = 1.40; 95% confidence interval [CI], 0.40‐4.96, P = 0.60). Among the 15 dogs that relapsed, 10/15 (67%) relapsed once, 3/15 (20%) relapsed twice, and 2/15 (13%) relapsed 3 times. No statistical difference was detected in the incidence rate ratio (IRR) of total relapse events between the 2 groups (IRR = 1.46; 95% CI, 0.61‐3.48; P = 0.40). Conclusions and Clinical Importance: "Short" 6‐week prednisolone protocols could be used to treat SRMA, thereby presumably reducing the duration and severity of prednisolone's adverse effects.

Background: Romiplostim, a thrombopoietin analog, is commonly used to treat immune‐mediated thrombocytopenia (ITP) in humans, but its use in dogs remains limited. Objectives: Evaluate the effects and adverse events of romiplostim administration in dogs with thrombocytopenia caused by various underlying diseases. Animals: Forty‐two client‐owned dogs with naturally occurring thrombocytopenia at 2 referral animal hospitals. Methods: Retrospective, multi‐institutional analysis to evaluate the outcomes of romiplostim treatment in dogs. Results: Among the dogs treated with romiplostim, 27 experienced an increase in platelet count and 26 maintained a platelet count within the reference range. Platelet count improvement was observed in various conditions: primary ITP (90%, n = 18/20), pancytopenia of unknown etiology (42.9%, n = 3/7), chemotherapy‐induced thrombocytopenia (50%, n = 3/6), babesiosis (100%, n = 1/1), radiotherapy‐induced thrombocytopenia (0%, n = 0/1), and disseminated intravascular coagulopathy (33.3%, n = 2/6). The median time for platelet recovery (>50 000/μL) after romiplostim administration was 4 days, and the median time for platelet count normalization was 7 days. Median hospitalization time for the improvement group (I) was 5 days. The survival‐to‐discharge rates were 85%, 40%, and 28.6% for dogs with primary ITP, secondary thrombocytopenia, and thrombocytopenia of unknown etiology, respectively. Conclusions and Clinical Importance: Romiplostim is a well‐tolerated and promising treatment for primary ITP in dogs, suggesting its potential as a valuable therapeutic option for dogs with thrombocytopenia caused by various underlying conditions. These findings emphasize the need for further research to optimize romiplostim dosing and understand its role in treating secondary thrombocytopenia and pancytopenia of unknown etiology.

Background: Equine parvovirus hepatitis (EqPV‐H) can cause Theiler's disease and subclinical hepatitis in horses. Objectives: Assess the frequency of subclinical EqPV‐H infection in hospitalized horses and to study viral transmission by investigating potential shedding routes. Animals: One hundred sixteen equids, that presented to the University Equine Hospital of the University of Veterinary Medicine Vienna between February 2021 and March 2022, for causes other than hepatopathy. Methods: In this cross‐sectional study, samples (serum, feces, nasal, and buccal swabs) of hospitalized horses were collected. Sera were screened for the presence of anti‐EqPV‐H antibodies by a luciferase immunoprecipitation system assay. Quantitative PCR was used for the detection of EqPV‐H DNA in the samples and a nested PCR was used for further validation. Results: Seroprevalence was 10.3% (12/116) and viremia occurred in 12.9% (15/116) of the serologically positive horses. The detected viral load in serum varied from non‐quantifiable amount to 1.3 × 106 genome equivalents per milliliter of serum. A low viral load of EqPV‐H DNA was detected in 2 nasal swabs and 1 fecal sample. Conclusion and Clinical Importance: EqPV‐H DNA was detected in nasal secretions and feces of viremic horses, which could pose a risk to naive hospitalized horses. It is advisable to screen hospitalized horses that are potential donors of blood or plasma to reduce the risk of iatrogenic EqPV‐H transmission. [ABSTRACT FROM AUTHOR]

Background: The prognosis of individual dogs with meningoencephalomyelitis of unknown etiology (MUE) remains difficult to predict. MUE cases with no lesions detected by magnetic resonance imaging (MRI) occur, but it is unknown whether this finding is associated with prognosis. Hypothesis: MUE cases without detectable lesions on MRI have a better outcome than cases with detectable lesions. Animals: Study included 73 client‐owned dogs with MUE presenting to Purdue University Veterinary Hospital from 2010 to 2020. Methods: Retrospective study. Dogs with a clinical diagnosis of MUE were identified by medical record search. MRI reports were reviewed for presence or absence of lesions consistent with MUE. Clinical findings at presentation, treatment, disease‐specific survival, and outcomes including rates of remission and relapse were compared between cases with normal MRI or abnormal MRI. Results: Overall, 54 dogs (74%) were classified as abnormal MRI, and 19 dogs (26%) were classified as normal MRI cases. Death caused by MUE occurred in 1/19 (5%) normal MRI dogs and 18/54 (33%) abnormal MRI dogs (P =.016). Median survival was >107 months in both groups, but survival was significantly longer in the normal MRI group (P =.019). On multivariate analysis, abnormal MRI was significantly related to death (hazard ratio, 7.71; 95% confidence interval 1.03‐58.00, P =.0470), whereas significant relationships with death were not identified for either the use of secondary immunosuppressive medications or cerebrospinal fluid nucleated cell count. Conclusions: MUE dogs with no detectable lesions on MRI have reduced disease‐related death compared with dogs with abnormal MRI. The presence or absence of MRI lesions in MUE dogs is prognostically relevant. [ABSTRACT FROM AUTHOR]

OBJECTIVE To assess the level of anxiolysis achieved by alprazolam and gabapentin in hospitalized cats prior to elective ovariohysterectomy and to evaluate the sedative effects of these agents. ANIMALS 60 client-owned female cats classified as American Society of Anesthesiologists physical status 1, admitted for elective ovariohysterectomy at a veterinary teaching hospital. METHODS The cats were prospectively and randomly allocated into 3 groups. Ninety minutes before evaluation, group G received gabapentin (100 mg/cat), group A received alprazolam (0.125 mg/cat), and group P received no medication (placebo). Stress, enclosure activity, and sedation scores were blindly evaluated. RESULTS Stress scores were similar in cats treated with gabapentin and alprazolam and gabapentin-treated cats had significantly lower stress score than those of the placebo group. Enclosure activity levels did not differ among the groups. Additionally, gabapentin and alprazolam resulted in similar sedation levels 90 minutes after treatment, which differed significantly compared to placebo. CLINICAL RELEVANCE The results of this study suggest that gabapentin provides similar anxiolysis in cats to that of alprazolam when evaluated 90 minutes after administration. Although no difference was noted in sedation levels between gabapentin and alprazolam. both induced deeper sedation than placebo. [ABSTRACT FROM AUTHOR]

OBJECTIVE To identify risk factors associated with peripheral intravenous catheter (PIVC) complications in cats hospitalized in the critical care unit (CCU). ANIMALS 120 cats admitted to the CCU between October 2022 and September 2023. METHODS This prospective, observational study was performed at a single veterinary teaching hospital. Cats hospitalized in the CCU for ≥ 24 hours were evaluated for enrollment. Peripheral intravenous catheters were placed by trained personnel following a standardized protocol and monitored for complications. PIVC complications were classified as extravasation, phlebitis, dislodgement, occlusion, line breakage, or patient removal. RESULTS Median PIVC dwell time was 42.25 hours (range, 24.25 to 164.25 hours). Overall PIVC complication rate was 18.3% (22/120), with extravasation (7/120 [5.8%]) and dislodgement (7/120 [5.8%]) being the most frequently recorded complications. Multivariable analysis identified that for each kilogram increase in body weight there is a higher likeli- hood of a PIVC complication (OR, 1.46; 95% CI, 1.03 to 2.05; P = .03). Additionally, use of a larger-gauge (20-gauge vs 22-gauge) PIVC is associated with a significantly lower likelihood of a PIVC complication (OR, 0.13; 95% CI, 0.03 to 0.56; P=.006). CLINICAL RELEVANCE These results suggest that smaller-gauge (22-gauge) PIVCs and greater body weights are associated with an in- creased risk of complications in cats hospitalized in the CCU. When possible, a larger-gauge (20-gauge) PIVC should be placed in cats admitted to the CCU. [ABSTRACT FROM AUTHOR]

This article explores the historical methods of delivering veterinary services to animals. It discusses how veterinarians used to travel on horseback or in horse-drawn carriages, carrying their instruments in saddlebags. With advancements in technology, motorized vehicles became the norm, and virtual veterinary services have also emerged. The article also touches on the establishment of veterinary schools and the importance of designated clinic locations. It further delves into the history of automobiles used by veterinarians, including the popular Ford Model T "Doctor's Coupe" in the 1920s. The use of modified vehicles for difficult road conditions and the development of mobile veterinary units are also mentioned. The article concludes by discussing larger motor vehicles and trailers equipped with examination and surgical facilities for at-home health services. Additionally, it explores the evolution of communication methods, such as videoconferencing, which have facilitated telemedicine in veterinary practices. [Extracted from the article]

Eclampsia is an acute and potentially fatal metabolic disease caused by a decrease in blood calcium levels. The initially symptoms observed in eclampsia are restlessness, excessive aggression and related behaviors, followed by abnormal gait, dyspnea, hypersalivation, hyperthermia, tachycardia, convulsion and ataxia. In this case, it was aimed to report the clinical and laboratory findings of eclampsia after birth in a Pekingese dog and the experiences gained during the treatment process. The research material consisted of a female Pekingese dog brought to Dicle University Veterinary Faculty Animal Hospital with complaints of inadequacy and convulsions. In the clinical examination, tachycardia, tachypnea, hypersalivation, trismus, inability to stand and hyperemic appearance of the mucosa and conjunctiva were determined, while the rectal temperature was determined to be 40.2 °C. It was observed that some parameters of the complete blood count and serum biochemical analysis results were not within the reference ranges. Subcutaneous caffeine, intravenous of calcium and 5% dextrose were administered to the dog, which was diagnosed with eclampsia. In the physical examination performed on the last day of the treatment, it was detected that there was an improvement and as a result of the hematological and serum biochemical analyses, all values were within the physiological reference range and the treatment was completed.

Importance: Feline calicivirus (FCV)-associated viral systemic disease (VSD) is a severe systemic disease caused by virulent FCV strains and has a very poor prognosis. Objective: To evaluate the clinical characteristics of a nosocomial FCV-VSD outbreak involving 18 cats in Korea. Methods: Medical records of cats diagnosed with FCV-VSD from March to September 2018 at a referral veterinary hospital were reviewed. The patient's signalment, history, clinical features, diagnosis, treatment, and prognosis were evaluated. Results: Two outbreaks involving 18 cats diagnosed with FCV-VSD occurred over a 6-month period at a referral hospital in Korea. Anorexia, lethargy, fever, and limb edema were the most commonly observed clinical symptoms. Lymphopenia and macrothrombocytopenia were the most common hematological findings, and hyperbilirubinemia and increased levels of aspartate aminotransferase, creatine kinase, and serum amyloid A were the most frequent results of serum biochemistry. FCV was detected by reverse transcription polymerase chain reaction in 11 patients and the remaining 7 were suspected with FCV-VSD. The overall mortality rate was 72.2%. The hospital was closed and disinfected twice, and no additional outbreaks have occurred since the last patient. Conclusions and Relevance: The clinical and diagnostic characteristics and outcomes of FCV-VSD described in this study can be used to recognize and contain infectious diseases through quick action. To the best of the authors' knowledge, this is the first report of a nosocomial outbreak of FCV-VSD in Asia. [ABSTRACT FROM AUTHOR]

Simple Summary: In people with respiratory diseases, treatment through inhalation is widely recommended and standardized. In veterinary medicine, few studies have investigated the effectiveness of treatments by the inhalation route. Among other factors, tolerance to the method used to administer the aerosol is key to its therapeutic success. This study has standardized a cough provocation test in cats using nebulized capsaicin at increasing concentrations and, through its use, compared the effectiveness and tolerance of the four methods most used in veterinary hospitals to administer oxygen and nebulized solutions. The results provide a cough challenge protocol that can be used in future studies for diagnostic and therapeutic purposes in cats with respiratory diseases. The protocol established that nebulization with a facial mask is the most effective, and nebulization in a chamber is the best tolerated. The flow-by method is a good alternative, but the hood method has poor cat tolerance. Successful aerosol therapy might rely more heavily on proper drug delivery than on the effectiveness of the medication. This study compared four techniques for nebulization delivery in cats. Tolerance rate (TR) was subjectively evaluated (1–3). Increasing capsaicin concentrations were nebulized for objective evaluation of efficiency. The positive response (PR) was considered when more than five coughs were induced. The following delivery methods were tested: flow-by (FB); face mask (FM); plastic-covered Elizabethan collar (EC); and plexiglass chamber (PC). The number of PRs (NPR) and the concentration of capsaicin that induced a PR (CCP) were statistically compared (p < 0.05). The PC method was the best tolerated (TR = 3.0 ± 0.0), followed by the FB (2.7 ± 0.5) and FM (2.6 ± 0.5). The EC was very stressful, and the test had to be suspended in four out of nine cats. The lowest CCP was found with the FM (91.8 ± 157.2 µM), followed by the FB (166.7 ± 190.9 µM), PC (242.6 ± 244.8 µM), and EC (350.0 ± 225.7 µM), with significant differences only between the FM and EC (p = 0.02). The highest NPR (8) corresponded to the FM, followed by the FB (7), the PC (5), and the EC (3), with significant differences between the FM and EC (p = 0.016). In conclusion, the capsaicin cough test induces reproducible and quantifiable cat responses. The FM is the most efficient for nebulization delivery, offering good compliance and the best quantitative results. FB nebulization is less efficient but may be practical if the FM is not tolerated. PC offers minor efficiency but may be useful for very stressed or aggressive cats. The EC presents low efficiency and compliance. [ABSTRACT FROM AUTHOR]

Simple Summary: In this retrospective medical record study, we evaluated if certain diagnostic variables, including Serum Amyloid A (SAA), could differentiate (1) between various clinical disease categories and (2) between cytological findings of severe hepatic lipidosis and other cytological findings in cats diagnosed with increased liver enzymes at a Swedish animal hospital. Grouping into four clinical disease categories (primary liver diseases, trauma, extrahepatic diseases, and other non-specified diagnoses) was based on clinical diagnosis or information from medical records. Serum Amyloid A was found to be higher in the group of cats with diagnoses supporting trauma. Cats with cytological findings supporting severe hepatic lipidosis had lower SAA and were younger, compared to cats with other cytological findings. Distinguishing inflammatory from non-inflammatory liver disease in cats may impact management. The study aim was to evaluate if certain diagnostic variables, including Serum Amyloid A (SAA), differ (1) between various clinical disease categories (Primary liver disease, Extrahepatic, Trauma and Inconclusive) and (2) between cytological findings of severe hepatic lipidosis and other cytological findings in cats with increased liver enzymes. Medical records from 5042 cats, where SAA had been measured, were reviewed, and 566 cats fulfilled inclusion criteria consisting of increased liver enzymes and available biochemical panel results. SAA was higher in cats diagnosed with trauma compared to other diseases (p = 0.008). Cytology results were available in 85 cats, and cats with severe lipidosis had lower serum SAA concentration (p < 0.0001) and were younger (p < 0.0002) compared to cats with other cytological findings. The study shows that SAA was higher in cats diagnosed with trauma compared to cats with other causes of increased liver enzymes and that SAA may be useful to distinguish cats with cytologic evidence of hepatic lipidosis from cats with other liver pathologies. Serum Amyloid A may be a valuable complement to liver cytology when investigating cats with increased liver enzymes. [ABSTRACT FROM AUTHOR]
