colitis in rhesus macaques ().

Abstract

is a-like bacteria associated with watery diarrhea in humans and is infrequently reported in nonhuman primate (NHP) populations. While clinical and microscopic features in humans are indistinguishable fromspp. infection, descriptions of-associated colitis in NHP are lacking. Here, we describe the clinical and pathological features of diarrhea and colitis associated within rhesus macaques using a retrospective approach. Over a 3-year period,was isolated from 10 macaques with diarrhea. Five of the 10 were submitted for necropsy and had features of chronic enterocolitis, consistent with existing literature. However, 40% (2/5) of the cases were characterized by ulcerative colitis, which has not previously been described as a feature ofcolitis.should be considered a differential diagnosis in cases of diarrhea and enterocolitis in captive rhesus macaques.
