Acute disseminated toxoplasmosis in a captive three-toed sloth (Bradypus tridactylus).

Fatal toxoplasmosis was diagnosed in a captive three-toed sloth (Bradypus tridactylus), an arboreal species of the tropical rainforests of South and Central America. In view of its specialized lifestyle and ecosystem and its low metabolic rate, B. tridactylus would seem to warrant further investigation in respect of its susceptibility to Toxoplasma gondii.
