Survey of anti-Toxoplasma gondii antibodies in wild mammals captured from Atlantic Forest fragments in Bahia, northeastern Brazil

The objective of this study was to investigate the frequency of antibodies to Toxoplasma gondii present in wild mammals that were trap captured in forest fragments in the State of Bahia, northeastern Brazil. A total of 368 individuals (246 rodents, 104 marsupials and 18 bats) were captured using liv...

description The objective of this study was to investigate the frequency of antibodies to Toxoplasma gondii present in wild mammals that were trap captured in forest fragments in the State of Bahia, northeastern Brazil. A total of 368 individuals (246 rodents, 104 marsupials and 18 bats) were captured using live catch traps. Serum samples were tested using the modified agglutination test, with a cut-off point at 1:25 dilution. The total occurrence of antibodies to T. gondii was 10.6% (39/368), being 16.3% (17/104) in marsupials, 8.5% (21/246) in rodents, and 5.5% (1/18) in bats. Antibody titers varied between 25 and 50 for rodents, between 25 and 400 for marsupials, and were 25 for bats. This is the first report on antibodies to T. gondii in certain rodent species (Thaptomys nigrita, Hylaeamys laticeps, and Cerradomys subflavus), marsupial species (Monodelphis americana, Gracilinanus microtarsus, Gracilinanus agilis and Marmosops incanus), and bats of the genus Rhynchonycteris. The presence of antibodies to T. gondii in wild mammals demonstrates the possibility of these animals as sentinels of toxoplasmosis, especially on regions under high anthropogenic effect.
