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. Methods One hundred and seventy-two fecal specimens were examined with the methods of saturated salt water floating and potassium dichromate cultivation method. Results The chicken coccidia infection rate was 100% and seven kinds of Eimeria were found in all, namely, Eimeria necatrix, Eimeria acervulina, Eimeria maxima, Eimeria tenella, Eimeriamitis, Eimeria hagani and Eimeria praecox. Conclusion The infection of chicken coccidian existed widely in the investigated area of Anhui province.
