The protozoan parasite Toxoplasma gondii can infect virtually all warm-blooded animals worldwide but little is known of its infection in the endangered giant anteaters (Myrmecophaga tridactyla). The present study found antibodies to T. gondii in 13 of 23 free-living M. tridactyla from the northwest region of São Paulo state, Brazil, by the Modified Agglutination Test (MAT, cut-off titer 1:25). Unfrozen tissues of seven M. tridactyla were bioassayed in mice and viable T. gondii (strain designated TgMytrBrSP1) isolated from one seropositive giant anteater. To our knowledge, this is a new host record for T. gondii. Genotyping using PCR-RFLP revealed the Brazilian clonal Type BrIII genotype, and a unique non-archetypal genotype was revealed by microsatellite analysis.
