Zusammenfassung: | This paper reports eleven cases of ulcerative and granulomatous enteritis associated with Molineus torulosus parasitism in different species of neotropical primates of the Sapajus genus. All of the affected monkeys had been apprehended by the environmental police and were being treated in a rehabilitation center for wild animals. The clinical history was weight loss and debility. During the necropsy, several nodules were found on the duodenum and proximal jejunum wall, with ulcers on the adjacent intestinal mucosa, including the nodules in the pancreas of four monkeys. Histologically, eosinophilic granulomas were observed in the small intestine, associated with fibrosis, eggs and adult models of Trichostrongylidae, etiology consistent with Molineus torulosus. This study describes the first cases of parasitism in Sapajus flavius, a species previously considered extinct, but recently rediscovered, and presents the occurrence of M. torulosus in two other species, Sapajus libidinosus and Sapajus apella.
RESUMO: São relatados 11 casos de enterite ulcerativa e granulomatosa associada ao parasitismo por Molineus torulosus em diferentes espécies de primatas neotropicais do gênero Sapajus. Todos os macacos afetados haviam sido apreendidos pela polícia ambiental e estavam sendo tratados em um centro de reabilitação de animais silvestres. O histórico clínico era de emagrecimento e debilidade. Durante a necropsia, foram constatados diversos nódulos na parede do duodeno e jejuno proximal, com úlceras na mucosa intestinal adjacente, além de nódulos no pâncreas de quatro macacos. Histologicamente, observou-se no intestino delgado, granulomas eosinofílicos associados à fibrose, ovos e exemplares adultos de tricostrongilídeos, etiologia consistente com Molineus torulosus. O presente trabalho descreve os primeiros casos de parasitismo em Sapajus flavius, uma espécie antes considerada extinta e recentemente redescoberta, e relata a ocorrência de M. torulosus em outras duas espécies, Sapajus libidinosus e Sapajus apella. |
