Deskripsi
ABSTRACT: This study aimed to evaluate exposure of wild small mammals to spotted fever group (SFG) rickettsiae in Mato Grosso do Sul State, central-western Brazil. Serum samples of 68 small mammals were analyzed by indirect immunofluorescence assay (IFA) against six Rickettsia species from Brazil. Overall, 37.5% (9/24) marsupials and 6.8% (3/44) small rodents were seroreactive to at least one of the Rickettsia species, with end point titres ranging from 64 to 512. These results suggested that wild small mammals were infected by SFG rickettsiae, and could participate in the ecology of rickettsiae in Mato Grosso do Sul, Brazil.
