Natural Infection of the Wild Canid Lycalopex gymnocercus by the Protozoan Rangelia vitalii, the Agent of Canine Rangeliosis.

Rangelia vitalii is a piroplasmid that causes canine rangeliosis, a severe hemorrhagic disease of domestic dogs in South America. We report about R. vitalii infecting a pampas fox (Lycalopex gymnocercus). The fox, which developed a fatal illness, was also infected by Hepatozoon canis and Capillaria hepatica.
