ABSTRACT: The puma (Puma concolor Linnaeus, 1771), the most widely distributed felid species in the Americas, can be found in all Brazilian biomes. Nevertheless, few studies have focused on hemoparasites in this species. Cytauxzoon felis, a hemoparasite that can infect domestic cats, has also been described in wild felids in Brazil. To the best of our knowledge, this study is the first to diagnose the natural infection and molecular detection of C. felis in a P. concolor in the state of Goiás. This animal presented non-regenerative anemia and inclusion suggestive of piroplasmids within red blood cells. The amplified 551 bp fragment of partial Piroplasmida 18S rRNA gene sequence was 100% identical to corresponding sequences of C. felis available in GenBank. No specific treatment for cytauxzoonosis was administered, and after rehabilitation, the animal was reintroduced into the wild. This finding provides some evidence that P. concolor may act as a natural host of the parasite. The epidemiology, vector and pathogenicity of this hemoparasite in wild and domestic cats in Brazil deserves further investigation.
