RESUMO

Five tamarins (four Saguinus mystax and one S. labiatus) died with wasting syndrome characterized by chronic diarrhea at the Center for Reproduction and Conservation of Non-Human Primates in Iquitos, Peru. At necropsy, the terminal ileum of all affected tamarins was found to be markedly thickened. Histologically, the terminal ileal mucosa was completely ulcerated, and effaced by debris and mononuclear inflammatory cells. The submucosa and serosa were thickened by fibroplasia, mononuclear cell infiltrates and variable edema. No infectious agent was observed. The lesions were similar to those described previously for Crohn disease. This is to our knowledge the first report of terminal ileitis resembling Crohn disease in non-human primates.

RESUMO

Of the 232 tamarins (133 Saguinus mystax and 99 Saguinus labiatus) that died at the Center for Reproduction and Conservation of Nonhuman Primates in Iquitos, Peru from January 1987 to December 1990, 23 monkeys (9.9%) were diagnosed as having chronic colitis. Typically, the cecal and colonic mucosa was greyish and small yellowish cysts, measuring 1-4 mm, were found randomly distributed bulging the mucosa. Microscopically, colitis cystica profunda was diagnosed additionally in six more animals, giving a total of 29 cases (12.5%). This is the first report to our knowledge that describes colitis cystica profunda in a nonhuman primate.

RESUMO

A wild-caught adult female Saguinus mystax died after 54 months in captivity. At necropsy, a small reddish zone in the renal cortex of one kidney was shown histologically to be a hemangiosarcoma.

RESUMO

A wild-caught male Aotus vociferans died spontaneously during quarantine. Histologic examination of the heart showed several small myocardial arteries replaced with fibrinoid necrosis and adjacent inflammation that included lymphocytes and large histiocytic cells. Less often, similar inflammatory foci were observed in the myocardium interstitium. The lesions observed in the heart of the owl monkey resembled Aschoff bodies.

RESUMO

Clinical and pathologic data were reviewed for 72 owl monkeys that died between January 1987 and May 1990 at the Center for Reproduction and Conservation of Nonhuman Primates in Iquitos, Peru. Tissue samples from 39 animals were examined. Hypertrophic cardiac disease (51% of animals examined), dilative cardiomyopathy (26%), and nephropathy (87%) were the most common diagnoses. The incidence of all three diseases appeared to increase with time in captivity. Nephropathy was less severe in colony-born animals.
