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.

摘要

对里约热内卢州苏尔弗卢米嫩塞帕拉伊巴河谷微区域的牛进行了弓形虫病调查，从位于雷森德和里奥克拉罗市的29个奶牛场的589头动物身上采集了血清样本。采用间接免疫荧光试验（IFAT）进行血清学检测，将弓形虫抗体滴度≥64视为阳性。在这两个市的检测结果显示，血清反应阳性的动物占14.8%。按各市分别分析结果时，雷森德的阳性动物占15.3%（314头中有48头），里奥克拉罗为14.2%（275头中有39头）。在对58个研究的奶牛场进行分析时发现，其中38个（65.5%）有抗弓形虫阳性奶牛，雷森德有20个（69.0%），里奥克拉罗有18个（62.1%）。关于IFAT检测中发现的血清学样本，79头（13.41%）动物抗体滴度为64呈阳性，6头（1.02%）为256，2头（0.34%）为1024，没有动物抗体滴度≥4096。
