From a total of 224 Didelphis marsupialis examined, in 15 were found cysts of Besnoitia in muscles and viscera. It's the first time that this protozoan is isolated from naturally infected animals in Brazil. The experimental transmission to laboratory animals was done by the inoculum of tissue and cysts triturated.
