【摘要】 为了摸清内蒙古自治区鸡致病性大肠埃希氏菌的血清型及其它生物学特性而进行了本课题的研究。内蒙古自治区七个盟市的九个具有代表性的养鸡场中从死鸡胚和死雏鸡中分离到203株大肠埃希氏菌。死胚的分离率平均为20％,雏鸡为35％。经血清型鉴定发现所分离的大肠埃希氏菌分别属于O₈、O₇₈、O₁₅、O₁₁₃、O₂₆、O₁₄₉、O₂、O₂₀、O₉₁、O₁₁₁、O₂₉血清型,其中以O₈和O₇₈分布最广,上述血清型中除O₁₄₉无致病性外,均属于鸡致病性大肠埃希氏菌血清型更多还原

【Abstract】 Escherichia coli to chick and its other biological properties in Inner Mongolia was carried out. 203E. coli strains were isolatied from dead embryos and chicks on nine Ghicken farms of seven Leagues and Cities in Inner Mongolia. the average isolation rate was 20% in dead embryos and 35% in dead chickens. Through the serotipe identification it was found that the serotipes, of E. coli isolated belonge to O₈、O₇₈、O₁₅、O₁₁₃、O₂₆、O₁₄₉、O₅₅、O₈₁、O₁₁₁and O₂₉. Among them the O₈ and O₇₈ were widely distributed. Except O₁₄₉, all serotipes isolated belonge to pathogenic E. Coli to chicks.更多还原
