A 3‐year‐old female neutered ferret presented with progressive weight loss was diagnosed with portosystemic shunting based on increased fasting bile acids, rectal ammonia tolerance testing and advanced imaging. Ammonia reference values were determined in 16 healthy ferrets. A congenital extrahepatic spleno‐caval shunt was visualised with ultrasonography and CT angiography of the abdomen. Complete surgical shunt closure by suture ligation was performed, without clinical improvement after surgery. Euthanasia was elected 4 months postoperatively because the clinical condition deteriorated. This is a case report of advanced diagnostics and surgical treatment of a congenital extrahepatic portosystemic shunt in a ferret, demonstrating rectal ammonia tolerance testing and imaging as feasible techniques for the diagnosis.

Active thermal devices are used to prevent hypothermia during anaesthetic procedures. Two thermal devices, one conductive and one convective, were compared for their effect on maintenance of core body temperature (CBT) during 1 h of general anaesthesia in pigeons (Columba livia domestica). In a randomised crossover trial, CBT decreased significantly less with the conductive device than when the convective device was used (2.5 ± 0.7 °C and 3.8 ± 0.9 °C, respectively; P < 0.01). Moreover, CBT was maintained above a clinically acceptable level of 38.3 °C in 82% of pigeons when the conductive device was selected, compared to 14% of pigeons with the convective device. The use of the conductive device is therefore recommended in preference to the convective device when performing anaesthetic procedures in birds. [ABSTRACT FROM AUTHOR]

The article discusses the findings of the amputation of carpal myxosarcoma and forelimb in a ferret. The study involves a three-year-old neutered male ferret presented as a referral to the University of Georgia College of Veterinary Medicine's Veterinary Teaching Hospital with a history of growing mass on the left carpus. Information on the clinical trial and its findings regarding the amputation are further discussed.

The article reflects on study conducted on seborrheic rabbits with differential diagnoses, including malnutrition, ectoparasites, and yeast dermatitis. It states that thymic lymphoma in rabbits is associated with exfoliative dermatitis. It further states that the oncological treatment and symptomatic protocols for canine sebaceous adenitis shows clinical signs.

Recognition and accurate assessment of the severity of pain can be challenging in ferrets as they are unable to verbally communicate, and often hide their pain. Pain assessment relies on the assessment of behavioral, physiologic, and other clinical parameters that serve as indirect indicators of pain. Assessment of physiologic and clinical parameters requires handling, which results in changes in these parameters. Behavioral parameters can be assessed less invasively by observing the patient. Due to their nonspecificity, correct interpretation may be challenging. Just as in other species, a grimace scale seems to be the most helpful tool in recognizing pain in ferrets., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2022 Elsevier Inc.

Chlamydia (C.) caviae is a known pathogen in guinea pigs, causing conjunctivitis, respiratory infections and abortions. Recently, a C. caviae -induced zoonotic link was identified as the etiology of severe community-acquired pneumonia in humans. Here, 784 conjunctival and rectal swabs originating from 260 guinea pigs and 110 rabbits from 64 husbandries in Switzerland, as well as 200 composite conjunctival swabs originating from 878 guinea pigs from 37 husbandries in The Netherlands were examined by real-time PCR followed by conventional PCR and sequencing. Chlamydiaceae were detected in 2.3% (18/784) and 12.5% (25/200) of all Swiss and Dutch samples, respectively. An overall C. caviae occurrence was detected in 2.7% (7/260) and 8.9% (78/878) of all Swiss and Dutch guinea pigs, respectively. OmpA genotyping of 64 C. caviae -positive samples resulted in 33 sequences sharing 100% nucleotide identity with the strains isolated from the zoonotic transmission cases in The Netherlands. However, all ompA sequences of this study were distinct from the C. caviae GPIC reference strain. C. caviae was not detected in rabbits but C. psittaci genotype A was identified in guinea pigs and rabbits, raising concerns about the importance of these animal species as novel zoonotic sources for C. psittaci .

The use of behavior modifying drugs may be considered in birds with behavior problems, especially those refractory to behavior modification therapy and environmental management. To accomplish behavior change, a variety of drugs can be used, including psychoactive drugs, hormones, antihistamines, analgesics, and anticonvulsants. Because their prescription to birds is off-label, these drugs are considered appropriate only when a sound rationale can be provided for their use. This requires a (correct) behavioral diagnosis to be established. In addition, regular monitoring and follow-up are warranted to determine the efficacy of the treatment and evaluate the occurrence of potential adverse side effects., (Copyright © 2017 Elsevier Inc.

Neoplasia has long been reported as a rare finding in rabbits, but over the past decades the number of reports on neoplastic disease in rabbits has risen considerably. Similar to other animals, neoplastic changes may occur in any organ system, but the rate in which the organ systems are affected differs considerably. In rabbits, tumors have predominantly been found in the urogenital, hemolymphatic, and integumentary systems. This article discusses current insights on the etiopathogenesis, clinical signs, diagnosis, and treatment of the commonest neoplastic diseases in rabbits and offer guidelines for the correct diagnosis and treatment of the rabbit oncologic patient., (Copyright © 2016 Elsevier Inc.

A 6-year-old, castrated male ferret (Mustela putorius furo) was presented with progressive neurological signs consisting of a right-sided head tilt and ataxia. Neurological examination revealed hemiparesis and absence of proprioception on the right side, consistent with central vestibular syndrome. Measurement of blood glucose excluded hypoglycemia due to insulinoma. Contrast-enhanced computed tomography revealed the presence of an intracranial mass, consistent with either granuloma or neoplasia. Palliative treatment with prednisolone yielded no improvement. At postmortem examination, a final diagnosis of a choroid plexus papilloma originating from the fourth ventricle was made. This is the first report of such a tumor in a ferret.

A 4-year-old rabbit was presented with a chronic exfoliative dermatitis and patchy alopecia. General physical examination revealed no abnormalities. Skin scrapings and fungal culture were negative. A blood sample was obtained for a complete blood cell count and biochemical profile, and yielded results that were within normal limits. Radiographic examination of the thorax excluded the presence of a thymoma. Histopathology of the skin showed orthokeratotic hyperkeratosis, absence of sebaceous glands and mural lymphocytic folliculitis, consistent with sebaceous adenitis. Oral treatment was started with ciclosporin dissolved in a medium-chain triglyceride solution (Miglyol 812), combined with essential fatty acids and topical propylene glycol sprays. Within 2 months of treatment, complete regression of skin lesions and regrowth of hair was observed. Serum chemistry values including kidney and liver function tests remained within reference range during the course of treatment. Histopathological examination of control biopsies of the skin showed presence of normal sebaceous glands and active hair follicles. Treatment was changed to a different pharmaceutical formulation of ciclosporin without Miglyol and deterioration of clinical signs was noticed. Using pure Miglyol 812, however, resulted in a gradual improvement of 60%. A nearly complete response was again observed after re-administration of the combination ciclosporin/Miglyol. It is hypothesized that sebaceous adenitis in the rabbit is most likely due to an autoimmune reaction directed at the sebaceous glands and a defect in lipid metabolism. The outcome indicates that a combination of ciclosporin and Miglyol 812 is a promising new treatment for sebaceous adenitis in rabbits.

Three mixed-bred raptors (Falco rusticolus x Falco cherrug) from a German falcon breeder were presented with a history of respiratory distress. In one bird a laryngeal stridor was noted, and oral examination revealed an epiglottal swelling. In the other two birds, nasal discharge and sneezing were the main clinical symptoms. Nasal flushing samples and biopsies were collected for pathologic, bacteriologic, and parasitologic examination. Results confirmed a cryptosporidial infection. Polymerase chain reaction (PCR) and DNA analysis identified the causative agent to be Cryptosporidium baileyi. No cryptosporidia were detected in fecal samples, indicating the infection was confined to the respiratory system. Analysis of prey animals (pigeons, quail) failed to identify the source of infection. Treatment was initiated with paromomycin in all three birds, whereas in two birds an additional therapy with azithromycin was given. However, no clinical improvement was seen after several weeks of treatment, and the birds either died or were euthanatized. To the authors' knowledge, these are the first confirmed cases of disease caused by cryptosporidia in the order of Falconiformes.
