Like domestic cats, wild felids are involved in the complete infective cycle of because they can host in their gastrointestinal tract sexually mature parasites and shed infective oocysts in their feces. We report, to our knowledge, the first isolation and molecular characterization of a strain from the heart tissue of a free-living jaguar () in French Guiana. Sequencing at six polymorphic markers indicated that the jaguar isolate had an atypical genotype, including an allele at previously found only in isolates from South America, and an allele at , which was previously reported only in Californian sea otter isolates. These findings are consistent with the recent description of atypical strains involved in severe toxoplasmoses in immunocompetent patients in French Guiana that seemed to be linked to a neotropical forest-based cycle involving wild cats and their prey.
