A captive juvenile little bustard (Tetrax tetrax) was presented for acute onset of right head tilt and right circling. The bird failed to respond to supportive care and systemic antibiotic therapy. A bilateral granulomatous and fibrinoheterophilic otitis interna due to Pseudomonas aeruginosa was diagnosed postmortem by histopathologic examination and bacterial culture. In bustards, Pseudomonas species have been documented in the normal bacterial flora of the oropharynx and are frequently reported in upper respiratory tract infections. This is the first report of a peripheral vestibular syndrome due to P aeruginosa otitis interna in a bustard species. Pseudomonas aeruginosa should be included as a possible cause of otitis and peripheral vestibular syndrome in bustards. © 2015 by the Association of Avian Veterinarians.

Hemangiosarcoma, hemangioma, transitional cell carcinoma, and chronic cystitis were diagnosed in the urinary bladder of six captive fallow deer (Dama dama). Hematuria and thin body condition were observed in the advanced cases. These findings were compatible with chronic enzootic hematuria and were suspected to have been induced by chronic ingestion of bracken fern (Pteridium aquilinum) present on the premises. These lesions were similar to those described in bovine enzootic hematuria in cattle. Hemangiosarcoma metastases, hydronephrosis, and renal carcinoma were also associated in some cases. This is the first report of hemangioma, hemangiosarcoma, transitional cell carcinoma, and renal carcinoma of the urinary bladder in fallow deer and the first indication of bracken fern intoxication in deer. © 2014 by American Association of Zoo Veterinarians.

A captive 3-yr-old male dhole (Cuon alpinus) was presented for poor body condition. Pancytopenia concurrent with bone marrow aspiration that revealed severe medullary infiltration by a population of initially small lymphocytes was diagnostic of an aleukemic chronic lymphocytic leukemia. Chemotherapy was initiated, but euthanasia was elected after the animal's rapid deteriorating condition and sudden lymphoid organs hypertrophy several days after initial presentation. Histology revealed lymphoid organs and bone marrow infiltration by highly proliferating immature lymphocytes compatible with a blast crisis. On immunohistochemistry, neoplastic cells appeared CD3 positive, confirming a T lymphoid origin. This is the first report of a lymphocytic leukemia in a wild canid species.

A clinically healthy 16-yr-old female leopard (Panthera pardus orientalis) was diagnosed with a patent ductus arteriosus on echocardiography and later confirmed on necropsy. A murmur was heard on auscultation during a routine examination, and the congenital defect was an incidental finding. The animal had been asymptomatic its entire life. This deformity is rarely observed in nondomestic felids and may be asymptomatic, as has been described in domestic cats. Copyright 2013 by American Association of Zoo Veterinarians.

A fatal case of encephalomyocarditis virus (EMCV) involving an African elephant (Loxodonta africana) occurred in November 2013 at the Réserve Africaine de Sigean, France. An adult female was found dead without any preliminary symptoms. Gross pathologic changes consisted of petechiae and hemorrhages on mucosae and internal organs, abundant transudate in the abdominal and pericardial cavities, and myocarditis. Histopathologic examination showed extensive degeneration and necrosis of ventricular cardiomyocytes with concurrent lymphoplasmocytic and eosinophilic infiltrate. An EMCV was isolated from several organs and considered the causative agent of the myocarditis. The same strain of virus was also isolated in rodents captured on zoo premises and considered to be the reservoir of the virus. To the authors' knowledge, this is the first EMCV case in a captive African elephant in Europe. © 2015 American Association of Zoo Veterinarians.
