摘　　要：目的了解安徽省五个县(区)鸡球虫种类及感染情况。方法采用群体采样法分别从个调查点采集新鲜鸡粪,检查粪样。阳性粪样采用饱和盐水漂浮和离心沉淀法进行卵囊分离。显微镜下观察卵囊进行虫种鉴定,并统计各调查点的鸡球虫感染率和感染强度等。结果检查172份鸡的新鲜粪样,得出鸡球虫感染率为100%;共检出7种球虫,经鉴定均隶属于艾美耳属,分别为毒害艾美耳球虫(Eimeria necatrix),堆型艾美耳球虫(E.acervulina),巨型艾美耳球虫(E.maxima),柔嫩艾美耳球虫(E.tenella),和缓艾美耳球虫(E.mitis),哈氏艾美耳球虫(E.hagani)和早熟艾美耳球虫(E.praecox)。结论鸡球虫在安徽省的这5个县(区)普遍存在,且有的调查点感染强度很高。Objective In order to investigate infection and species of chicken coccidian in Anhui province.
