Sera of 204 cows in Jaboticabal, S.P., Brazil were examined by indirect immunofluorescent test for detecting anti-Toxoplasma antibody. Assuming titers from 1:64 as indicative of toxoplasmic infection it was observed 32.3% of positive reactions. The antibody titers even to 1:256 represented 7.8% of the reacting animals. The serological titers varied from 1:64 to 1:256. No clinical story could be correlated with the reacting animals and no isolation was performed.
对巴西圣保罗州雅博蒂卡巴尔市204头奶牛的血清进行了间接免疫荧光试验，以检测抗弓形虫抗体。假设滴度从1:64起表明存在弓形虫感染，观察到阳性反应率为32.3%。抗体滴度甚至达到1:256的反应动物占7.8%。血清学滴度在1:64至1:256之间变化。未发现与反应动物相关的临床病例，也未进行分离培养。
