Prevalence of IgG antibodies specific to Toxoplasma gondii among college stu dent blood donors in Shijiazhuang City

目的了解石家庄市大学生献血者弓形虫感染情况。方法 2012年3-10月采集石家庄市4所大学大学生献血者和健康体检成人血清标本,采用酶联免疫吸附试验(ELISA)检测弓形虫感染情况。结果共检测石家庄市4所大学864例大学生献血者和95例健康成人,弓形虫IgG阳性率分别为5.1%和7.4%,差异有统计学意义(P<0.05)。男性和女性大学生献血者弓形虫IgG阳性率分别为5.0%和5.2%,差异无统计学意义(P>0.05);不同大学的大学生献血者弓形虫IgG阳性率差异无统计学意义(P>0.05)。结论大学生献血人群中部分感染弓形虫,有必要加强弓形虫病防控工作。
