ABSTRACT
BACKGROUND: Enteric diseases are among the most common causes of morbidity and mortality in gorillas, and it is often caused by bacteria. METHODS: A thirteen-year-old captive female western lowland gorilla (Gorilla gorilla gorilla) developed hemorrhagic diarrhea. Despite the treatment, the animal died 7 days after the onset of clinical signs. The animal was submitted to a thorough pathological and microbiological evaluation. RESULTS: Pathologic examination revealed a severe acute hemorrhagic colitis, neutrophilic splenitis, glomerulitis, and interstitial pneumonia. Salmonella enterica serotype Infantis was isolated from a mesenteric lymph node. CONCLUSION: A diagnosis of hemorrhagic colitis associated with Salmonella enterica serotype Infantis was established.

An 8-yr-old female paca (Agouti paca) was admitted at the Veterinary Hospital of the Belo Horizonte Zoo (Brazil) with an ulcerated cutaneous nodule of approximately 1.5 cm in diameter in the left ear. One week later, other cutaneous nodules were detected in various body locations. The animal died during a surgical procedure to remove the tumors. All cutaneous nodules were histologically similar with features of squamous cell carcinoma. Considering the predominant in situ nature of the lesion as well as its multicentric localization, the disease reported here closely resembles Bowen's disease, which has been described in humans and which has been identified as a rare neoplastic disease of cats, with one single report in a dog. This is the first report of a neoplastic disease in Agouti
