Localized, myocardial toxoplasmosis contributed to the death of a female ring-tailed lemur (Lemur catta) 1 week after the delivery of 4 stillborn offspring with disseminated toxoplasmosis; the diagnosis was obtained by histopathology and immunohistochemistry in all 5 lemurs. Varying degrees of placentitis and placental edema with intralesional Toxoplasma gondii immunolabeling were observed in the 3 available placentas. The dam had severe myocarditis, and T. gondii antigen was only detected in the myocardial lesions. Disseminated toxoplasmosis with mild encephalitis was noted in all 4 fetuses, and 2 of the fetuses had mild acute multifocal hepatic necrosis. Fetal death was attributed to placental insufficiency with subsequent hypoxia and amniotic fluid aspiration. © 2011 American Association of Veterinary Laboratory Diagnosticians.
