摘要
采用单种卵囊分离技术建立了鹅艾美耳球虫(Eimeria anseris)克隆株,并对其基本生物学特性进行了研究。卵囊呈梨形,一端截平,另一端钝圆。卵囊壁单层,光滑无色或淡黄色,狭窄截平端有卵膜孔。无极粒,外残余体似一块不规则的塞状物,位于卵膜孔的正下方。测量100个卵囊,平均大小为19.37μm×16.06μm,形状指数为1.20。孢子囊卵圆形,斯氏体明显,有内残余体。测量100个孢子囊,平均大小为9.09μm×6.83μm。潜在期为168~173h,显露期为107~118h,最短孢子发育时间为55h。用不同剂量感染时,Eanseris的繁殖力差异显著(P〈0.05)。
A clone strain of Eimeria anseris was developed. The oocysts were shaped like a sphere surmounted by a truncate cone with a smooth, colorless, I-layered wall, a residuum and a micropyle ; without a polar granule. Oocysts were measured in 19. 37 μm×16.06μm, and the shape index was 1.20. The sporocysts were ovoid with a stieda body, and measured in 9. 09 μm×6.83μm. The minimum sporulatic time was 55 h; the prepatent period was 168 - 173 h; the patent period was 107 - 118 h. The reproductivity was affected by doses of oocysts significantly ( P 〈 0. 05 ).
