摘　　要：用纯种斯氏艾美耳球虫孢子化卵囊人工感染25只断奶幼兔,进行致病性和病理学研究。试验兔分为1个不感染对照组和4个感染组,各感染组每只幼兔分别口服感染2.0×103、1.0×104、5.0×104、2.5×105个孢子化卵囊。与对照组相比,接种2.0×103个和1.0×104个孢子化卵囊的两个感染组的平均病变记分、肝重指数、血清转氨酶活性有显著差异(P<0.05);接种5.0×104个和2.5×105个孢子化卵囊的两个感染组上述指标有极显著差异(P<0.01)。表明斯氏艾美耳球虫对幼兔具有很强的致病性,能导致严重的肝球虫病。In order to study the pathogenicity and pathology of Eimeria stiedai, 25 young rabbits were infected artificially by purified sporulated oocysts of Eimeria Stiedai （E.stiedai）. These rabbits were divided into 5 groups, one control group and four experimental groups. The sporulated oocysts were inoculated orally to four experiment groups with the dose of 2.0 × 10^3, 1.0 × 10^4, 5.0 × 10^4 and 2.5 × 10^5, respectively. The results showed that there were significantly differences in mean pathogenic scores, liver index, transaminase and pathologic histology between control and experimental groups （P〈0.05 or P〈0.01）, indicating that E.stiedai may have a strong pathogenic effect in severe liver coccidiosos in young rabbits.
