Results found in both municipalities were 14.8% serum reagents animals. When these results were analyzed by each Municipality, Resende had 15.3% (48 animals of 314) positive animals, and 14.2% (39 animals of 275) was observed at Rio Claro. In the analysis of 58 studied dairy farms was observed that 38 (65.5%) of them having positive cows for anti-T. gondii, being 20 (69.0%) at Resende, and 18 (62.1%) at Rio Claro.
