摘要
采用群体采样法分别从安徽省六安、寿县、霍邱三地调查点采集新鲜鸡粪,检查粪样。阳性粪样采用饱和食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。调查结果:检查50份鸡的新鲜粪样,得出鸡球虫感染率为100%;共检出6种球虫,经鉴定均隶属于艾美耳属,分别为毒害艾美耳球虫(Eimerianecatrix)、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.tenel-la)、缓艾美耳球虫(E.mitis)和早熟艾美耳球虫(E.praecox)。调查结果说明:鸡球虫在皖西地区普遍存在,且有的调查点感染强度很高,养殖户的科学防治意识不强。
The fresh chicken feces were collected from invesgation points of 3 locations of Liuan, Shouxian and Huoqiu by population sampling method for feces detection. The oocysts were isolated from positive feces samples by saturation salt solution float method and centrifugal sedimentation method. The oocysts were obserVed under microscope for species identification and the infection rate and intensity of chicken coccidia of all the investigation points were calculated. The results indicated that in the 50 checked fresh chicken feces samples, the infection rate of chicken coccidia was 100 %, 6 species of coccidia were detected and they were E. necatrix, E. acervulina, E. maxima, E. tenella, E. mitis and E. praecox of the genus Eimeria resp. It was illustrated that chicken coccidia was universial in west Anhui region and in some investigation points, its infection intensity was very high and the scientific control awareness of raising households was not strong.
