Fatal infection with human pinworm, Enterobius vermicularis, in a captive chimpanzee

A fatal infection with human pinworms, Enterobius vermicularis, was found in a 26‐year‐old chimpanzee kept in a zoo. Grossly, the animal was highly emaciated, and had severe enteritis with cecal multifocal nodules and severe cholelithiasis. Histopathologically, a large number of human pinworms were observed in the nodular lesions in the cecum and intestinal wall. These migrating worms were surrounded by an inflammatory cell infiltration which lacked eosinophils. There were areas of multifocal hyperemia and/or hemorrhages in various organs including the entire gastrointestinal tract. Pinworms were also observed in the portal venule and parenchyma of the liver. A light infection with Strongyloides cf. stercoralis was also observed.

Lingual squamous cell carcinoma in an ocelot (Felix pardalis).

ALTHOUGH squamous cell carcinoma (scc) is relatively common in the oral cavities of cats (Head 1990, Baker and others 1993), there have been few reports of oral scc in captive, wild felidae maintained in zoos (Effron and others 1977, Griner 1983, Hubbard and others 1983). Only one case of gingival scc has been reported in a Canadian lynx (Lynx canadensis) (Gunson and others 1978). This short communication describes the postmortem examination of an ocelot (Felispardalis) which had scc of the tongue. A 19-year-old female ocelot was admitted for treatment because of severe anorexia and depression. On admission, the animal was markedly thin and had varying degrees of alopecia. The animal died while in a coma six weeks after admission. The animal had been sent to the Kobe City Oji Municipal Zoo as a young adult from Woodland Park Zoo in Seattle, USA, and was kept there for 15 years for display and breeding purposes. It had given birth several times. Necropsy was performed immediately after death by veterinary staff from the

Advanced gastric carcinoma in a de Brazza's guenon (Cercopithecus neglectus).

Abstract: A necropsy case of advanced gastric carcinoma in a 20‐year‐old female de Brazzas guenon (Cercopithecus neglectus) was studied. Grossly, an excavated carcinoma mass, 60 × 55 × 35 mm in size, was located in the cardiac region of the stomach. Multiple disseminated nodules had implanted on the diaphragm and omentum. The tumor consisted of intestinal‐type adenocarcinoma cells and showed infiltrative growth beyond the serosa. The morphologic features of this tumor closely resembled those of advanced gastric carcinomas in human patients.
