Abstract
The aim of this study was to determine if Toxoplasma gondii was present in aborted bovine fetuses in Brazil. Histopathology of 105 cases with suspected infectious abortion, analyzed during the period from 2006 to 2008 at Centro de Pesquisa e Desenvolvimento de Sanidade Animal of Instituto Biológico, São Paulo, showed 75 cases with indications of abortion due to apicomplexan protozoa. These cases were submitted to PCR for verification of the laboratory diagnosis. Fetal DNA was extracted from central nervous system, heart, liver, muscle, and/or placenta samples to obtain a 529 bp DNA fragment. T. gondii DNA was not detected in any of the bovine fetuses analyzed, suggesting that it may not be a frequent cause of bovine abortion.
