Dyscoria was noted in a female owl monkey and 2 of her offspring. The third offspring was found dead with necrohemorrhagic encephalitis. Two male monkeys paired with the female died, 1 of which showed oral ulcers at necropsy. Histologic examination of the oral ulcers revealed syncytia and eosinophilic intranuclear inclusion bodies in epithelial cells. Ocular examination revealed posterior synechia associated with the dyscoria in all 3 animals. Serum samples from the female and her offspring were positive for Herpesvirus simplex antibodies by ELISA. The clinical history, gross and microscopic lesions, and serology results suggests a herpesviral etiology, possibly H. simplex or H. saimiri 1. This report underscores the risks associated with introducing into breeding or research colonies animals that previously were kept as pets or those from unknown origin that could carry asymptomatic pathogenic Herpesvirus infections. In addition, herpesviral infection should be considered among the differential diagnoses if dyscoria is noted in nonhuman primates.
