Abstract

Diarrheal disease associated with abortions and stillbirths occurred in a group of 42 Macaca fascicularis. The group was composed of wild-caught adults and their colony-born offspring housed in a half-acre cage. Thirteen adult females and 1 infant male were affected. All 14 monkeys had diarrhea and all 9 pregnant females either aborted or had a stillbirth. Yersinia pseudotuberculosis was isolated from 7 animals. In addition, Y enterocolitica was isolated from 1 monkey and Shigella flexneri type IV was isolated from 5 monkeys. One adult female had a mixed infection of both Y pseudotuberculosis and S flexneri. Every pregnant monkey from which Y pseudotuberculosis was isolated aborted or had a stillbirth. Five animals died, and Y pseudotuberculosis was the only pathogen isolated from these 5 monkeys.
