title: [Prevalence of anti-Toxoplasma gondii antibodies in dairy cattle from Sul Fluminense Paraíba Valley, State of Rio de Janeiro].
abstract: A survey of toxoplasmosis in cattle from Sul Fluminense Paraiba Valley micro region in the State of Rio de Janeiro was realized, where serum samples were collected from 589 animals of 29 dairy farms located at municipalities of Resende and Rio Claro. Serology was performed by using indirect immune fluorescent test (IFAT), and considering as positive to Toxoplasma gondii titles > or = 64. 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. With regard to serologic samples found in the IFAT, 79 (13.41%) animals were positives with titles of 64, six (1.02%) with 256, two (0.34%) with 1024, and none of animals had titles > or = 4096.
