ABSTRACT

Like domestic cats, wild felids are involved in the complete infective cycle of Toxoplasma gondii 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 T. gondii strain from the heart tissue of a free-living jaguar (Panthera onca) in French Guiana. Sequencing at six polymorphic markers indicated that the jaguar isolate had an atypical genotype, including an allele at TgM-A previously found only in isolates from South America, and an allele at GRA6, which was previously reported only in Californian sea otter isolates. These findings are consistent with the recent description of atypical T. gondii 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.
