Aelurostrongylus abstrusus is the most important respiratory nematode of domestic cats. Effective control options are crucial to protect health and welfare of cats and to reduce the spread of aelurostrongylosis in both enzootic and free regions. The present study evaluated the efficacy of a spot-on formulation containing 280 mg/ml fluralaner and 14 mg/ml moxidectin (Bravecto® Plus, MSD) in the prevention of aelurostrongylosis in cats under field conditions. One hundred and fifty-two cats from Italy, Hungary and Bulgaria, were randomly divided in two groups, one treated with Bravecto® Plus on Study Days (SDs) 0 and 84 (74 cats, IVP Group) and one left untreated (78 cats, control group). Faecal samples were collected from all animals on SDs 42 ± 4, 84, 126 ± 4 and 168 ± 4 and subjected to the Baermann's technique and species-specific PCR for A. abstrusus. Each cat was subjected to a clinical examination on SDs 0, 84 and 168 ± 4 to check health condition and possible adverse events. The results of the faecal analysis were statistically analyzed for treatment group differences in the percentage of cats negative to the Baermann's test and PCR and percentage of reduction of fecal larvae counts as the primary and secondary efficacy criteria, respectively. The percentage of negative cats was higher in the IVP group compared to the control group and the percentage of reduction of fecal larvae counts in the IVP group compared to the control group was 100%. These results show that two administrations of Bravecto Plus® spot-on 12 weeks apart were safe and effective in the prevention of aelurostrongylosis for a period of almost 6 months. • The nematode Aelurostrongylus abstrusus causes a major respiratory disease in cats. • Chemopreventative approaches are advocated in enzootic areas. • Bravecto ® Plus, MSD, containing 280 mg/ml fluralaner and 14 mg/ml moxidectin, was useful to prevent aelurostrongylosis. • Chemoprophylaxis is an effective strategy to prevent cat aelurostrongylosis.

Giardia duodenalis is the most common intestinal protozoan in humans and animals worldwide, including eight morphologically identical assemblages, infecting pets, livestock, wildlife and human beings. Assemblages A and B are those with the higher zoonotic potential, and they have been detected in several mammals other than humans; the others (C to H) show a higher host specificity. Cats can harbour both the specific Assemblage F and the zoonotic ones A and B. Several studies have been carried out on G. duodenalis genotypes in cats; however, the role of this species in the epidemiology of giardiasis is still poorly understood. In this scenario, the present study carried out the detection and genetic characterization at sub‐assemblage level of G. duodenalis from colony stray cats in central Italy. In the period 2018–2019, 133 cat faecal samples were analysed for the presence of G. duodenalis cysts by a direct immunofluorescence assay. Positive samples were subsequently subjected to molecular analyses for assemblage/sub‐assemblage identification. Forty‐seven samples (35.3%) were positive for G. duodenalis cysts by immunofluorescence. G. duodenalis DNA was amplified at SSU‐rDNA locus from 39 isolates: 37 were positive for zoonotic Assemblage A and 2 showed a mixed infection (A + B). Positive results for the β‐giardin gene were achieved for 25 isolates. Sequence analysis revealed 16 isolates belonging to Sub‐assemblage AII and 8 to Sub‐assemblage AIII. One isolate resulted as ambiguous AI/AIII. Large sequence variability at the sub‐assemblage level was detected, with several double peaks and mutations, making complex a proper isolate allocation. When compared with previous studies, the 35.3% prevalence of G. duodenalis in cats reported in the present article was surprisingly high. Moreover, all positive cats resulted to be infected with zoonotic assemblages/sub‐assemblages, thus indicating stray cats as a possible source of human giardiasis and highlighting the sanitary relevance of cat colonies in the study area.

Two cats infected by Dirofilaria immitis and Dirofilaria repens, respectively, were taken to two different private practitioners for a clinical examination. The analyses conducted on the first cat revealed a microfilaraemia due to D. repens of 66 mfs/mL by a modified Knott's test. No clinical signs of D. repens infection were observed in the cat. The animal was euthanised because of a lymphoma condition, and two adult females of D. repens were found in the subcutaneous tissue of the lumbar and left scapular regions at the post-mortem examination. The second cat showed severe abnormalities in the white blood cells, including eosinophil count. Microfilariae of D. immitis were detected in the blood smear, with an average length (n = 2) of 296.2 μm. These clinical cases represent the first reports of feline dirofilarioses in southern Italy and are indicative of a common occurrence of dirofilarial infection in the local canine population.

Background: Parasites that infect cats include protozoa, helminths and arthropods, many of which are transmissible to humans. Effective control relies on a good knowledge of parasite distribution and the risk factors for infection. The present study was aimed at evaluating the prevalence of major feline parasites in Italy and the risk factors associated with their occurrence. Methods: Over a 12-month study period, feces, hair and ectoparasites from naturally infected cats from feral colonies, shelters and private households were analyzed at 13 study centers across Italy. Samples from these cats (n = 987) were analyzed at all centers using the same diagnostic methods. Prevalence values and risk factors were evaluated statistically for the identification of predictors of risk. Results: The overall prevalence of gastro-intestinal and broncho-pulmonary (BP) nematodes was 35.9% (354/987). Toxocara cati was the most prevalent species (253/987; 25.6%), followed by Ancylostomatidae (98/987; 9.9%). Among BP nematodes, Aelurostrongylus abstrusus was the most common (76/987; 7.7%). Approximately 35.7% (352/987) of the study population was infested by ectoparasites, of which the most common were fleas (29.4%, 290/987), followed by ear mites Otodectes cynotis (9.8%, 97/987). Predictors of risk for parasite infection included age, a predominantly or exclusively outdoor lifestyle, geographic area and lack of antiparasitic treatment. Conclusions: Both ecto- and endoparasites are still common in cats throughout Italy, many of them being of zoonotic concern and vectors of pathogens to humans. Given the presence of parasites throughout the entire study period, year-round treatment should be considered. Furthermore, data confirm the need to protect the human–animal bond using proper endo- and ectoparasiticides to reduce the risk of human infection, in application of the One-Health concept.

Background: Vaccination plays an important role in feline healthcare as it is the most effective measure for prevention against feline infectious diseases. Therefore, it is important to know owners' opinion towards cats' vaccination and current veterinary practices in order to advice owners on the use of the correct vaccination protocol. This study aimed to investigate the proportion of cats regularly vaccinated and identify the main factors motivating cat owners' decisions related to vaccination in Italy. A questionnaire was disseminated online (mainly via social networks) to collect data regarding Italian cat owners' demographics, information about cats, factors regarding cats' vaccination, and veterinary-owner relationship. Results: A total of 1264 owners participated in the survey and 1247 questionnaires were completed and statistically analyzed. The majority (91%; n = 1131) of cats were vaccinated and 80% (n = 998) had been vaccinated within the last 3 years. Age of 2–4 years old cats and the acquisition from a breeder or cat shop were significantly associated with vaccination within the last 3 years. Cats vaccinated but not within the last 3 years were significantly associated with cat's indoor lifestyle, cats' age ≥ 5 years old and low annual household income. Importance of vaccination cost, low annual household income and owners' job not related to healthcare was statistically associated with the lack of cat's vaccination. In addition, 86% of the owners took their cat regularly to veterinary clinics. Veterinarians play a significant role in owners' decision, and they are considered the most useful source of information about vaccination by 97% of owners. Conclusions: The high number of recently vaccinated cats suggests owner's attention towards feline vaccination and cat's health. The importance of veterinarian's advice along with the knowledge of factors associated to the unvaccinated status of cats may help veterinarians to grow owner's confidence and increase prevention of feline infectious diseases. However further investigations based on a more comprehensive sample of the general population are needed to confirm the results of this survey. [ABSTRACT FROM AUTHOR]

Almost 30 years after acceding to the Convention against Torture, in 2017 Italy introduced the crime of torture into its penal code. There was great debate as to whether the new provisions were in line with the country's international obligations. The first interpretations of these rules by the highest criminal court draw heavily on international notions, in particular on the case-law of the European Court of Human Rights. The result is that, while the wording of the provisions remains questionable, their application tends to be consistent with (at least some) international rules. [ABSTRACT FROM AUTHOR]

Background: Feline vector-borne pathogens (FeVBPs) have been increasingly investigated for their impact on cat health and their zoonotic potential. The aim of the present study was to assess the prevalence of FeVBPs and haemoplasmas in cats across Italy and to identify potential risk factors linked to their occurrence. Methods: Blood samples from 958 owned cats living in the North (n = 556), Centre (n = 173) and South (n = 229) of Italy were tested for Babesia spp., Hepatozoon spp., Ehrlichia spp., Anaplasma spp. and filarioids by conventional PCR (cPCR) and for haemoplasmas and Bartonella spp. by SYBR green real-time PCR. Cats included in the study represent a sub-sample from a larger number of animals enrolled in a previous study, which were selected based on the geographical origin. Data on cats' positivity for Leishmania infantum, feline leukaemia virus (FeLV) and for feline immunodeficiency virus (FIV), available from the previous study, were included and examined. Potential risk factors for pathogen infection were assessed in relationship to categorical variables including sex, geographical origin, breed, neutering status and age of cats. Results: Out of the 958 cats, 194 (20.2%) were positive for at least one of the tested pathogens, 89 (16%) from the North, 32 (18.5%) from the Centre and 73 (31.9%) from the South of Italy. A high prevalence of FeVBPs was detected in male cats (n = 125, 27.8%), living in the southern part of the country (n = 73, 31.9%), younger than 18 months of age (n = 24, 22.4%) and not neutered (n = 39; 27.5%). In particular, 24 cats (2.5%) tested PCR-positive for Bartonella spp., of which 1.6% for B. henselae and 0.9% for B. clarridgeiae. A total of 111 cats scored PCR-positive for haemoplasmas (11.6%), specifically "Candidatus Mycoplasma haemominutum" (n = 95, 9.9%), M. haemofelis (n = 14, 1.5%) and "Candidatus Mycoplasma turicensis" (n = 2, 0.2%). Moreover, 39, 31 and 8 cats were positive for FeLV (4.1%), L. infantum (3.2%) and FIV (0.8%), respectively. Co-infections were registered for 19 (9.8%) cats. Conclusions: These results confirm the occurrence of haemoplasmas and FeVBPs throughout Italy. Preventive measures to protect both animal and human health should be carried out also for owned cats, even if no health status of animals has been assessed in this study. [ABSTRACT FROM AUTHOR]

Feline lungworms affect the respiratory tract of domestic cats causing respiratory conditions of various degrees. In this study, we investigated the exposure of cats to feline lungworm infections by detecting antibodies in a large population of animals from several regions of Italy. Sera of 1087 domestic cats living in regions of the north (n = 700), the centre (n = 227) and the south (n = 160) of Italy were examined by a newly developed indirect ELISA conceived for detection of antibodies against the most frequently occurring feline lungworm Aelurostrongylus abstrusus. Individual cat data (i.e., age, sex, neutering status and provenience) were analysed as potential risk factors for exposure to lungworm infections. Samples were additionally screened for feline leukaemia virus (FeLV) and feline immunodeficiency virus (FIV) proviral DNAs. Overall, 9% (98/1087; 95% confidence interval (CI) 7.4–10.9%) of the animals tested seropositive to lungworm antibodies. Positive cats were identified in the north (7.1%; CI 5.5–9.3%), in the centre (5.3%; CI 3.0–9.0%) and in the South (22.5%; CI 16.7–29.6%), with more seropositive animals in the latter area (p < 0.05). The risk of lungworm infection in cats was significantly associated with age less than 6 months (i.e. 24.4%, p < 0.05) and FIV infection (p < 0.05). This large-scale serological survey confirms the exposure of cats to lungworm infections in Italy and that serological tests can be used to assess the distribution of lungworm infections in large populations of animals.

• Aelurostrongylus abstrusus is endemic in cat populations of Italy. • ELISA test can overcome the Baermann limits in the detection of feline lungworms. • Higher rates of positive animals can be detected using antibodies detection. Aelurostrongylus abstrusus (Nematoda, Metastrongyloidea) is a worldwide occurring lungworm causing verminous pneumonia in cats. To date the Baermann method is the most used procedure to diagnose A. abstrusus infection by isolating first stage larvae from faeces, though its sensitivity and specificity can be impaired by several factors. An enzyme-linked immunosorbent assay (ELISA) for the detection of antibodies against A. abstrusus has been recently developed as a diagnostic alternative. The present study evaluated the seroprevalence for A. abstrusus infection in cats from two endemic areas of Italy. Overall, 250 sera were sampled and tested for the presence of antibodies against A. abstrusus. Based on the results obtained from 20 cats proven to be infected by A. abstrusus using Baermann technique and molecular methods, and from 20 negative cats (Subset A), a cut off value of 0.347 optical density (OD) was determined, leading to a sensitivity of 95% and a specificity of 100%. Two-hundred and ten cats (142 and 68 from Abruzzo and Umbria regions, respectively) were included in Subset B (i.e. 202 negative by Baermann examination and 8 positive for Troglostrongylus brevior). Antibodies against A. abstrusus were detected in forty-five (21.4%, 95% CI: 16.1–27.6%) samples. This study confirms the occurrence of A. abstrusus in endemic areas of Italy and indicates that one-fifth of randomly selected cats have or had a lungworm infection with production of antibodies.

Highlights • The questionnaire was sent to 2795 veterinary facilities. The response rate was 25%. • At least one case of Dirofilaria spp. in dogs has been diagnosed in 47% facilities and in 6% for cats. • To diagnose heartworm infection 83.8% of the facilities used serology. • Prevention of D. immitis was begun mainly in April-May. • Prevention of D. immitis in cats was not recommended in 51% of the facilities. Abstract Dirofilaria immitis and D. repens are vector-borne parasites of dogs and cats, with zoonotic potential, endemic in many parts of Europe, including Italy. Control and prevention of dirofilariosis are essential points to reduce their diffusion in animals and humans and veterinarians are the main subjects involved in this "battle". With the aim to better understand current practice by veterinarians, an online questionnaire on different aspects of D. immitis and D. repens was sent to companion animal veterinary facilities registered with the Italian Veterinary chamber. The overall response rate was 25%. Approximately 47% had diagnosed at least one case of Dirofilaria spp. in dogs in the last year and approximately 6% had diagnosed at least one case of Dirofilaria spp. in cats. Of the 662 facilities surveyed, 83.8% used serology to diagnose heartworm infection. For the diagnosis of D. repens infection in dogs and cats, a high percentage of facilities relied on an external laboratory. Most recommended beginning prevention of canine heartworm disease in April-May. Topical and injectable moxidectin and oral ivermectin were the two most commonly used preventives for D. immitis in dogs. The drug most commonly used for heartworm adulticide treatment in dogs was melarsomine. This study show that veterinary facilities ians working in an endemic area for D. immitis and D. repens are aware of recent developments in adulticide therapy. Results would suggest however that diagnosis is not always carried out according to what is currently recommended by international guidelines and that the timing for starting prevention may not be optimal.

Feline morbillivirus (FeMV) has been recently identified by RT-PCR in the urine sample of a nephropathic cat in Italy. In this report, we describe the whole genome sequence of strain Piuma/2015 obtained by combination of sequence independent single primer amplification method (SISPA) and next generation sequencing (NGS) starting from RNA purified from the infected urine sample. The existence in Germany and Turkey of FeMVs from cats divergent from Piuma/2015, suggests the presence of FeMV heterogeneity in Europe as it has been described previously in Japan and China.

Nematodes infecting the cardiorespiratory system of cats have recently stimulated high scientific interest. Over the past few years, different aspects of these parasites have been clarified and various issues elucidated. This increased knowledge has improved awareness on this topic but, at the same time, some dilemmas have not been solved and new questions have been raised. In this review, we underline and discuss current knowledge of, and new doubts relating to, feline lungworms and heartworms, with the aim of stimulating new studies to fill gaps of basic (i.e., epidemiology and biology) and applied (i.e., clinical aspects) knowledge of the old and new parasites affecting the cardiorespiratory system of cats.

Aelurostrongylus abstrusus is a metastrongyloid nematode infesting the respiratory system of domestic cats worldwide. Troglostrongylus brevior and Troglostrongylus subcrenatus, two lungworms thought to infest wild felids, have been found recently in domestic cats from Spain and Italy. These unexpected findings have raised doubts about the assumed past and present occurrence of Troglostrongylus spp., especially T. brevior, in domestic hosts and suggest that there may have been missed detection or misdiagnosis. The present retrospective study evaluated the presence of lungworms in cats from Italy with a diagnosis of respiratory parasitism or with compatible lung lesions from 2002 to 2013. Sixty-eight samples of DNA and larvae from cats with a diagnosis of aelurostrongylosis, and 53 formalin-fixed paraffin-embedded lung samples from cats confirmed as lungworm infested or with compatible lesions, were investigated using two DNA-based assays specific for A. abstrusus or T. brevior. All DNA and larval samples were positive for A. abstrusus and one was additionally positive for T. brevior. Most paraffin-embedded lung tissues were positive only for A. abstrusus, but two samples tested positive for both lungworms and one for T. brevior only. This study supports the major role of A. abstrusus in causing feline respiratory parasitism in endemic areas of Italy. [ABSTRACT FROM AUTHOR]

Oslerus rostratus syn. Anafilaroides rostratus (Strongylida: Filaroididae) is a metastrongyloid transmitted by snails, which localizes in peri-bronchial tissues and in the lung parenchyma of wild as well as domestic cats. In Europe, this nematode has been reported only on two occasions, being diagnosed in cats from Majorca Island and in northern Spain. Here, we describe a case of O. rostratus infection in a necropsied 4-year-old cat in Sicily (southern Italy). At the inspection of lungs, slender and greyish nematodes (four females and two males) were found embedded in the peri-bronchial tissues and in the bronchial walls. Parasites were morphological and molecularly identified as O. rostratus, with their 18S sequences being identical among them and showing a high homology (99 %) with those available in public databases. At the histology, nematodes were encapsulated in a pseudo-cystic formation surrounded by an interstitial inflammatory process and fibrous tissue. Lung lesions were mainly represented by peri-luminal fibrosis, hyperplasia and hypertrophy of the bronchial mucosa and glands, respectively. This first record of O. rostratus infection from Italy indicates that this parasite should be included in the differential diagnosis of feline of lungworm infection. [ABSTRACT FROM AUTHOR]

Abstract: In recent years Aelurostrongylus abstrusus has often been reported in Italy. This lungworm is very common in cat colonies due to its route of transmission. Deciding a therapeutic approach can be difficult in such colonies, because there is no certainty whether oral medicines administered with food, or with what dose, will be taken. In this field study, stool samples were taken from 42 cats and analysed for A. abstrusus L1 larvae with Baermann technique. Ten cats testing positive were treated with a spot-on formulation of selamectin 45mg. Clinical examinations and laboratory tests, repeated four times in two months, demonstrated the success of the treatment in 9 of the 10 cats. Improvements in respiratory signs and general clinical condition were reported after treatment. [Copyright &y& Elsevier]

Simple Summary: Cats have been closely linked to humans for thousands of years. Nowadays, stray cats are frequently hosted in colonies, protected, and enrolled in programs of trap–neuter-–return to control population increase. Italian public veterinary services work in collaboration with voluntary colony caretakers and are responsible for neutering and monitoring the health of colony cats. This retrospective study, conducted by the Anatomical Pathology Unit of the Teaching Veterinary Hospital of Milan in collaboration with the public veterinary services, was undertaken because of the limited information available regarding causes of death of colony cats. The study reports on and statistically analyzes the causes of death of colony cats in the city of Milan as assessed by necropsy. Inflammatory processes including those consistent with the most relevant feline infectious diseases were most common in kittens and young cats. Trauma was more frequent in adult cats, while organ failure was the most common cause of death in aged cats. Considering the possible animal welfare issues deriving from colony cats, awareness of the most common causes of death and collaboration between university veterinary pathologists and public veterinary services represent an essential contribution to health monitoring of colony cats and can assist in the rapid detection of possible emerging animal welfare concerns. The presence of cats in urban environments has a long history. In Italy, stray cats are protected by national and regional laws, and programs of neutering and reintroduction to colonies are ongoing. Colony cats have been widely studied from a behavioral perspective, while surveys regarding their causes of death are limited, although they may provide relevant information related to public health and cat welfare. This retrospective study provides pathological descriptions and statistical analyses of the causes of death of 186 cats from 100 colonies in the city of Milan. Inflammatory processes represent the primary cause of death (37.7%) and include common feline infectious diseases such as feline panleukopenia (67.5%), particularly in kittens, and feline infectious peritonitis (32.5%), most common in adult cats. Trauma was found to be a common cause of death of young/adult cats (14%) with a generally good body condition, while severe parasitosis was less represented (2.6%). The death of old cats was statistically associated with organ failure (24.7%), particularly renal failure, and tumors (11.8%). Knowledge of the most common causes of death of colony cats could make an important contribution to the health monitoring of these cats and sanitary control of their habitats and provide information on possible related emerging animal welfare concerns.

Orthpoxvirus infection can spread more easily in a population with a waning immunity with the subsequent emergence/re-emergence of the viruses pertaining to this genus. In the last two decades, several cases of Orthopoxvirus, and in particular Cowpoxvirus infections in humans were reported in different parts of the world, possibly due to the suspension of smallpox vaccinations. To date, in Italy, few investigations were conducted on the presence of these infections, and because of this a serosurvey was carried out to evaluate Cowpoxvirus infection in feline colonies situated in the province of Rome, since these are also susceptible to other zoonotic viruses belonging to Orthopoxvirus, and from which humans may contract the infection. The sample design was set at an expected minimum seroprevalence of 7.5%, a 5% standard error and 95% confidence level. In parallel, a serological investigation was conducted using convenience sampling in domestic, exotic and wild susceptible animals of the Latium and Tuscany Regions, which are areas in the jurisdiction of the Istituto Zooprofilattico Sperimentale del Lazio e della Toscana, coordinating this study. The serological methods employed were indirect immunofluorescence for 36 sera of nonhuman primate and virus neutralization for 1198 sera of different species. All the 1234 sera examined were negative for the presence of antibodies against Cowpoxvirus, indicating its limited circulation in the areas of investigation. The methodology applied for the serosurveillance could be adopted in the case of outbreaks of this infection and for the evaluation of the spread of this infection in the area of interest, to obtain essential information crucial for animal and public health policies according to the One Health concept.

Abstract: Serological and molecular surveys were conducted to determine the occurrence of Bartonella henselae in domestic cats in Central Italy. Samples from 234 pet cats were tested for B. henselae antibodies by indirect immunofluorescence with 78 (33.3%) positive. A PCR assay specific for the Bartonella 16S rRNA gene was carried out on DNA samples extracted from blood of the 234 cats; 26 (11.1%) of the seropositive cats were positive. Two PCR protocols, which discriminate genotypes I and II of B. henselae, were performed on all DNA samples. Sixteen (6.8%) cats were infected by genotype I, 6 (2.5%) by genotype II, and two males (0.8%) by both genotypes. Two female (0.8%) cats which were Bartonella sp. PCR positive, gave negative results with the types I and II PCR. This protocol facilitates the direct and rapid detection of Bartonella DNA in feline blood samples, and differentiates B. henselae genotypes. [Copyright &y& Elsevier]

Bartonella henselae and Bartonella clarridgeiae were isolated in two cats in Sardinia, Italy. Infection by B. clarridgeiae was characterized by fever and submandibular lymph nodes enlargement while B. henselae infection was asymptomatic.

No evidence of anti-NPA antibodies was observed. [ABSTRACT FROM AUTHOR]

Abstract: This survey was conducted to investigate the presence of Dirofilaria immitis and Dirofilaria repens in native dogs and cats living in an area of Italy where animal and human dirofilarioses have been sporadically reported in the past few years. From May 2008 to March 2009 individual blood samples were collected from 300 native cats and 300 native dogs in the Abruzzo region of central Italy. All 600 samples were subjected to a Knott modified method, to a test for the detection of circulating D. immitis antigen and to two species-specific PCR-coupled sequencing protocols. Epidemiological data were collected and then correlated with the filarial prevalence by univariate and multivariate statistical analyses. Twenty-five dogs (8.3%) and six cats (2%) were positive for filariae in at least one diagnostic test, with an overall prevalence rate for D. immitis and D. repens of 2.3% and 5.6% in dogs and 0.3% and 1.6% in cats, respectively. Male and large sized dogs resulted more likely to be infected by Dirofilaria spp., possibly due to the fact that animals living outdoor and of large size are more exposed to mosquito bites. However these factors were not confirmed as convincing risk factors by multivariate analysis. The results are discussed, together with the origin of these new autochthonous foci in central Italy and the present expansion southward of canine and feline filariae in Italy.

Objective To describe a case of a conjunctivo-corneal mass in a cat associated with acid-fast bacilli. Methods A 2-year-old female black European Short-Hair cat, living outdoors in a suburban environment in Italy, was referred for evaluation of a nodular, vascularized mass of 2 weeks duration. The mass involved the dorsal bulbar conjunctiva at the temporal canthus of OS and invaded the sclera and cornea. Routine ophthalmic and systemic examination, serologic testing, cytology and histology of the mass were performed. Mycobacterium specific polymerase chain reaction (PCR) of variable regions 1, 2 and 3 of the 16S ribosomal RNA (rRNA) gene was also performed. Results Neutrophils, lymphocytes, macrophages and giant cells with intracytoplasmic acid-fast bacilli were seen on cytological examination. The histological examination confirmed the presence of a granulomatous lesion with acid-fast bacilli within macrophages. Bacteriological culture of the material from the lesion was negative for Mycobacterium spp. Mycobacterium 16S rRNA gene specific PCR was positive. A diagnosis of feline leprosy was made. The owners refused any treatment, and 1 year later the lesion was still present. Conclusions Veterinary ophthalmologists should be aware of conjunctivo-corneal leproma as an unusual symptom of leprosy. [ABSTRACT FROM AUTHOR]

Feline morbillivirus (FeMV) was isolated for the first time in 2012 with an association with chronic kidney disease (CKD) suggested. This study aimed at investigating in cats from southern Italy FeMV prevalence and risk factors for exposure to FeMV, including the relationship with CKD; sequencing amplicons and analyzing phylogeny of PCR positive samples. Blood serum, K3EDTA blood and urine samples from 223 cats were investigated. Ten carcasses were also evaluated. FeMV RNA was detected in 2.4% (5/211) blood and 16.1% (36/223) urine samples. One carcass tested positive by qPCRFeMV from kidney, urinary bladder, and submandibular lymph nodes. Antibodies against FeMV were detected in 14.5% (28/193) cats. We followed up 27 cats (13 FeMV positive cats) and documented in some cases urine shedding after up to 360 days. Older and foundling cats and cats living in rescue catteries, were more frequently infected with FeMV. A significant correlation between FeMV and higher serum creatinine values or low urine specific gravity was found. FeMV positivity was significantly associated with retroviral infection, and the presence of some clinical signs apart from CKD clinicopathological markers. Our study highlights the possibility of a link between FeMV exposure and CKD and a general impairment of feline health. [ABSTRACT FROM AUTHOR]

Abstract: Infection by the cat lungworm Aelurostrongylus abstrusus is considered uncommon. Here, the authors report the clinical, diagnostic and therapeutic features of five infections recently observed in Italy. All cats were under 12 months of age. All except one cat had symptomatic infections, with cough, dyspnea, and weight loss with radiographic signs of broncopneumonia. All cats were eosinophilic. Larvae were present in fresh fecal smears and on flotation exam in all cats. Baermann larval recovery permitted definitive identification and, in one case, larvae per gram of feces (lpg) counts. One dose of ivermectin (400μg/kg) was not effective in one cat, while one dose of selamectin (6mg/kg) was effective in one of three cases and fenbendazole at 50mg/kg given daily for 15 days was effective in four of four cases.

In order to investigate the genotypes of Giardia duodenalis from domestic and farm animals in Italy, 21 Giardia isolates, 17 from dogs, 1 from cat and 3 from dairy calves, were genetically characterised by SSU-rRNA gene sequencing. Among dogs, 76.5% of isolates showed the dog-specific genotypes (Assemblages C, D and C/D mixed Assemblage) and 23.5% exhibit potential zoonotic genotypes (Assemblage A and A/C mixed Assemblages). The cat isolate belonged to assemblage A, whereas the sequences among the isolates from calves were found to correspond to hoofed-livestock genotype, namely Assemblage E. These findings suggest that infection of humans by zoonotic genotypes from domestic animals could be of low epidemiological significance, although possible. The present study represents the first contribute to the knowledge of G. duodenalis genotypes in domestic and farm animals from Italy. [Copyright &y& Elsevier]

Simple Summary: Pearsonema spp. nematodes live in the urinary bladder and sometimes in the ureters and renal pelvis of domestic and wild carnivores, in which they may be responsible for urinary capillariosis. While the red fox is considered a reservoir of Pearsonema plica, the occurrence of Pearsonema spp. infection in domestic carnivores is still poorly known. This study aimed to assess the occurrence of Pearsonema spp. infection in privately owned cats and dogs from central (Tuscany) and northern Italy (Piedmont and Lombardy) alongside its occurrence in a red fox population from central Italy (Tuscany). Among the examined animals, 2/26 cats (7.7%), 1/83 dogs (1.2%), and 38/42 foxes (90.5%) were found positive. Recurrent cystitis, pollakiuria, and hematuria were the main clinical signs in symptomatic dogs and cats. This is the first study on Pearsonema spp. infection of domestic carnivores examining a large number of privately owned pet animals. Obtained results confirm the role of the red fox as a reservoir for P. plica in Europe and suggest a possible high occurrence of Pearsonema spp. infection in domestic cats of central Italy. Pearsonema spp. nematodes infect the urinary bladder of domestic and wild carnivores. The red fox is considered a reservoir of Pearsonema plica, while the prevalence of Pearsonema spp. in domestic carnivores is still poorly known. This study aimed to assess the occurrence of Pearsonema spp. infection in privately owned cats (26) and dogs (83) from central and northern Italy alongside occurrence in red foxes (42) from central Italy. In positive dogs and cats, associated clinical signs were also evaluated. Urine samples were first examined under a stereomicroscope; then, they were centrifuged and microscopically examined after a flotation test. As for foxes, the urinary bladders were opened and urine was collected and processed as above, while collected nematodes were identified at the species level. Among examined animals, 2/26 cats (7.7%), 1/83 dogs (1.2%), and 38/42 foxes (90.5%) scored positive. Recurrent cystitis, pollakiuria, and hematuria were the main clinical signs in symptomatic dogs and cats. This is the first study on Pearsonema spp. infection in domestic carnivores examining a large number of privately owned pet animals. Obtained results confirm the role of the red fox as a reservoir for P. plica and suggest a possible high occurrence of Pearsonema spp. infection in domestic cats of central Italy.

Abstract: One hundred and eighty one cats living in central Italy were tested for the presence of Giardia and Cryptosporidium infection by IFAT test and specific PCRs. Overall eight (4.4%) samples were IFAT-positive for Giardia. All the IFAT-positive samples for Giardia scored positive for the PCRs, and three more samples IFAT-negative generated PCR products leading to a total 6.1% molecular positivity rate for Giardia. All the examined samples were negative for Cryptosporidium. Sequencing of samples molecularly positive to Giardia indicated that three cats harbored the zoonotic Giardia duodenalis Assemblage A, whereas all other positive animals were infected with the feline-specific G. duodenalis Assemblage F. Phylogenetic analysis carried out on the sequences obtained supported the clustering of the isolates within Assemblages A and F. The results here presented provide data on the occurrence of Giardia genotypes in cats living in close contact with humans highlighting the potential importance of this protozoan disease for the public health.

Abstract: The occurrence of the infection by the lungworm Eucoleus aerophilus (syn. Capillaria aerophila) in dogs and cats from Italy has been evaluated with conventional diagnostic procedures. Individual faecal samples from 569 dogs and 200 cats were undertaken to faecal flotation with sugar and zinc sulphate solution. Sixteen dogs (2.8%) and 11 cats (5.5%) scored positive for eggs of E. aerophilus when samples were processed with either of the two flotation solutions. Overall 14 of 16 dogs and eight of 11 cats infected by E. aerophilus showed respiratory symptoms and the most common were general respiratory distress, dry cough, wheezing and sneezing. These results indicate that E. aerophilus is not uncommon and that canine and feline capillariosis is of clinical importance. Given the impact that E. aerophilus infections may have upon animal health and its zoonotic potential, it is strongly advisable to routinely include this disease in the differential diagnosis of (cardio)-respiratory diseases of dogs and cats.

Aelurostrongylus abstrusus (Nematoda, Strongylida) lives in the terminal respiratory bronchioles and alveolar ducts of cats. The infection may present with respiratory signs of varying severity and can be life threatening. Despite the importance of A. abstrusus in feline medicine and recent reports of clinical cases of aelurostrongylosis in Italy, epidemiological data are sparse and molecular information available on the parasite are lacking. The present work reports recent insights into the epidemiology of feline lungworm infection in Italy and contributes to the molecular knowledge of A. abstrusus. Individual stool samples were collected from 100 animals and examined with flotation and Baermann methods. The risk factors were analyzed by binary logistic multiple-regression models. All positive fecal samples ( n= 16) were subjected to the PCR-coupled sequencing of the rDNA internal trancribed spacer 2 (ITS2). The detected infection rate differs significantly from data reported in the literature, and stray and free-ranging cats and the presence of respiratory symptoms were risk factors for the infection. The molecular characterization showed that the ITS2 sequence is a promising genetic target for a holistic approach to the study of cat lungworm infection. Epidemiological and molecular insights and avenues are discussed. [ABSTRACT FROM AUTHOR]

• Feline zoonotic Vector-Borne Diseases (VBDs) are endemic in Italy. • Privately owned indoor cats of Italy are exposed to zoonotic Vector-Borne Pathogens. • Chemoprevention against ectoparasite is advisable also in indoor cats. • Seropositive cats can either be asymptomatic or show non-specific clinical signs. • VBDs should be investigated in cats with unexplained increased liver enzymes. Zoonotic Vector-Borne Diseases (VBDs) represent a relevant health issue for pets and humans. Italy is a major epidemiological hub for feline VBDs, because of suitable conditions for vector biology and disease transmission patterns. The present study investigated the exposure to major zoonotic arthropod-borne pathogens of cats in Italy, along with the evaluation of clinic-pathological features and a risk factor analysis. Out of 167 examined cats, 52 (31.1%) were seropositive for at least one vector-borne pathogen, being positivity for Bartonella henselae the most recorded (18%). Also, various cats seroreacted for Rickettsia felis (10.8%) and Rickettisa typhi (4.2%), Leishmania infantum (3%), Anaplasma phagocytophilum (2.4%) and Ehrlichia canis (2.4%). Forty-six cats were tested also for antibodies against D. immitis and two (4.3%) scored positive. The statistical analysis showed a positive association between flea infestation and seropositivity to B. henselae , other than an association between the administration of monthly ectoparasiticide treatments and seronegativity for Rickettsia spp.; seropositive cats were older than negative animals and the lifestyle (i.e. indoor vs outdoor) was not correlated with exposure to vector-borne pathogens. The majority of seropositive cats appeared clinically healthy or showed aspecific clinical signs. Around 80% of seropositive cats had one or more biochemical and/or complete blood count abnormalities. The present data confirm the endemicity of zoonotic feline VBDs in Italy and indicate that awareness on arthropod infections and transmitted pathogens should be kept high and possible implemented, towards the protection of animal and human health with adequate surveillance plans.

• Methicillin-resistant S. pseudintermedius (MRSP) has emerged worldwide as a concern in small animal clinics. • Internationally established and novel MRSP clones are present in Italy. • MRSP isolates show a phenotypic and genotypic multidrug resistance, without diversity among different clonal lineage. • The MDR traits in the MRSP population highlights the importance of rational usage of antimicrobials in the dog population. • The zoonotic potential of MRSP of animal origin should not be underestimated. The aim of this study was to assess the prevalence, the genotypic diversity, the antimicrobial resistance traits of canine and feline clinical methicillin-resistant Staphylococcus pseudintermedius (MRSP) isolates in a diagnostic laboratory in Italy during 2015-2016. All isolates were characterized by multilocus sequence typing (MLST), staphylococcal cassette chromosome (SCC)- mec typing and staphylococcal protein A (spa)-typing. The resistance profiles were assessed by antimicrobial susceptibility testing and confirmed genotypically by the detection of mecA gene and by microarray analyses. The prevalence of MRSP isolates was high (31.6%). All the strains were multidrug resistant and the most frequent clone was ST71-SCC mec type II-III. These results confirm a high prevalence of MRSP amongst clinical samples from pets in Italy. These isolates show multidrug resistance features that are of concern both in veterinary and human medicine for clinical and epidemiological reasons. [ABSTRACT FROM AUTHOR]

Background: The query “are there animals at home?” is usually administered for collecting information on anamnesis. This modality to consider exposure to pet allergens constitutes a potential bias in epidemiological studies and in clinical practice. The aim of our study was to evaluate/quantify different modalities of exposure to cat/dog in inducing allergic sensitization. Methods: Thirty Italian Allergy units participated in this study. Each centre was required to collect the data of at least 20 consecutive outpatients sensitized to cat/dog allergens. A standardized form reported all demographic data and a particular attention was paid in relieving possible modalities of exposure to cat/dog. Results: A total 723 patients sensitized to cat/dog were recorded, 359 (49.65%) reported direct pet contact, 213 patients (29.46%) were pet owners, and 146 subjects (20.19%) were exposed to pets in other settings. Other patients were sensitized by previous pet ownership (150–20.75%) or indirect contact (103–14.25%), in 111 subjects (15.35%) any contact was reported. Conclusions: Only 213 patients (29.46%) would be classified as “exposed to animals” and 510 (70.54%) as “not exposed” according to usual query. Our classification has shown that many “not-exposed” subjects (399–55.19%) were “really exposed”. The magnitude of exposure to pet allergens at home is not related exclusively to pet ownership. These considerations should be taken into account during the planning of epidemiological studies and in clinical practice for the management of pet allergic individuals. [ABSTRACT FROM AUTHOR]
