Sera collected from 447 dairy cattle on 14 dairy farms were tested for Neospora caninum antibodies by use of an immunofluorescent antibody technique. Positive reactions with titres > or =1:200 were found in 63 (14.09%) of animals. Neospora positive sera were also tested for Toxoplasma gondii antibodies by using a commercial latex agglutination test. Antibodies to T. gondii were detected in 3 (4.76%) of 63 N. caninum positive sera. These results indicate that N. caninum infection is widespread among dairy cattle in Bahia state.
运用免疫荧光抗体技术，对来自14个奶牛场的447头奶牛采集的血清进行了犬新孢子虫抗体检测。在63头（14.09%）动物中发现了滴度≥1:200的阳性反应。还通过商业乳胶凝集试验对犬新孢子虫阳性血清进行了弓形虫抗体检测。在63份犬新孢子虫阳性血清中的3份（4.76%）检测到了弓形虫抗体。这些结果表明犬新孢子虫感染在巴伊亚州的奶牛中广泛存在。
