In order to determine the prevalence of anti-Toxoplasma gondii antibodies, 2000 serum samples from female dairy cattle belonging to 50 farms in the southwest of Mato Grosso state were analyzed by the indirect fluorescent antibody test (IFAT>=64). Serum samples from 61 dogs (IFAT>=40) and 116 humans (IFAT=40), all from the same farm, were also tested. Among these samples, 1420 (71.0%) cattle, 54 (88.5%) dogs, and 113 (97.4%) humans were seropositive for the infection. No significant differences (P >=0.05) were observed for risk factors associated with the occurrence of toxoplasmosis in humans due to contaminated sources such as fresh milk, cheese/sausage, and contact with felines or other animals. The presence of felines can indicate the likelihood of a contaminated environment, posing a risk to the human population and other animals. The work presented herein is the first report to evaluate the seroprevalence of T. gondii in bovines from the Southwest region of the Mato Grosso state, Brazil.
