为了解我国牛羊弓形虫病流行情况，应用间接血凝试验（IHA）对河南、山东、山西、内蒙古、云南、贵州6省区151份牛血清、50份奶样、490份羊血清进行了弓形虫病血清流行病学调查。结果显示：151份被检牛血清和50份牛奶样品，弓形虫抗体均为阴性。490份羊血清弓形虫抗体总阳性率5.71％，其中母羊、公羊血清阳性率分别为4.03％和9.79％；山羊、绵羊、杂交羊血清阳性率分别为6.58％、4.81％和5.13％；阳性率最高的为公山羊（13.2％），最低的为母绵羊（2.96％）。28份阳性羊血清中，75％的抗体滴度为1：64，25％的抗体滴度为1：256。1岁后的羊，随年龄增长，血清阳性率升高。

The objectives of this study were to determine the seroprevalence of Toxoplasma gondii in cattle,sheep and goat.151 serum samples from cattle,50 milk samples from cows,490 serum samples from sheep and goats were collected from Henan, Shandong,Shanxi,Neimenggu,Yunnan,Guizhou provinces. These samples’anti-T.gondii antibodies were examined using a com-mercial indirect hemagglutination assay kits. The result showed that specific IgG against T. Gondii of 151 samples from cattle were all negative;while in 490 samples from sheep and goats,the overall seroprevalence rate was 5.71%, the female and the male had different seroprevalences surprisingly(4.03%and 9.79%respectively);the goats,sheep,mixed-breed had comparable seropreva-lences(6.58%,4.81%and 5.13%,respectively),the male goats had the highest seroprevalence of T. gondii(13.2%)and the fe-male sheep had the lowest one(2.96%).In 28 positive samples,75%serum antibody titer was 1:64 and the 25%was 1:256. Sero-prevalence of T. gondii infection increased significantly with the age of the assessed sheep or goats after 1-year-old.
