Sheep are highly susceptible to infections with Toxoplasma gondii and play a major role in the transmission of toxoplasmosis to humans. In the present study, 779 serum samples from sheep were collected from Henan province, central China from March 2015 to May 2016, and antibodies to T. gondii were detected by modified agglutination test (MAT). The overall seroprevalence of T. gondii in sheep was 12.71% (99/779). The risk factors significantly associated with T. gondii seroprevalence were the geographical origin, age, presence of cats, and the rearing system. This is the first report of T. gondii infection in sheep in Henan province, central China, and of an association of seropositivity to T. gondii with risk factors.
绵羊对刚地弓形虫感染高度易感，在弓形虫病传播给人类的过程中起主要作用。在本研究中，于2015年3月至2016年5月从中国中部河南省采集了779份绵羊血清样本，采用改良凝集试验（MAT）检测抗刚地弓形虫抗体。绵羊中刚地弓形虫的总体血清阳性率为12.71%（99/779）。与刚地弓形虫血清阳性率显著相关的危险因素是地理来源、年龄、猫的存在以及饲养系统。这是中国中部河南省绵羊刚地弓形虫感染的首次报告，也是刚地弓形虫血清阳性与危险因素之间关联的首次报告。
