| Abstract | BACKGROUND Toxoplasma gondii is a apicomplexan parasite of virtually all warm-blooded species. All true cats (Felidae) can
act as definitive hosts for this parasite by shedding resistant oocysts into the environment. However, the patterns of oocysts
shedding are only partially understood in domestic cats and largely unknown in wild felids.
OBJECTIVES We carried out molecular analysis of 82 faecal samples from wild felids collected in the Serra dos Órgãos National
Park (Parnaso), Rio de Janeiro, Brazil.
METHODS We screened samples for T. gondii DNA using a quantitative polymerase chain reaction (qPCR) targeting the 529bp
DNA fragment. Polymerase chain reaction (PCR)-positive samples were genotyped using 15 microsatellite markers.
RESULTS Only one faecal sample from a Puma yagouaroundi was PCR-positive [cycle threshold (Ct) = 26.88]. This sample was
contaminated by a T. gondii strain of BrIII lineage, a common lineage in domestic animals from Brazil.
MAIN CONCLUSIONS This first report of T. gondii in faeces of wild South American felids in their natural environment indicates
infrequent oocyst shedding and suggests a role of acquired immunity in limiting re-excretion as in domestic cats. The presence
of a domestic strain of T. gondii in a faecal sample from a wild felid at very low concentrations (not detected by microscopy) is
consistent with the hypothesis of host-parasite co-adaptations limiting the circulation of T. gondii strains between domestic and
wild environments. | pt_BR |
