摘　　要：从 40例卵黄性腹膜炎病例分离到 36株大肠杆菌 ,分离率为 90 %。通过血清型鉴定 ,共有 9个血清型 ,即O5(2 0 8%) ,O8(16 7%) ,O78(12 7%) ,O14 1(12 5 %) ,O14 7(12 5 %) ,O18(12 3%) ,O19(5 6 %) ,O14 (4 9%)和O15(2 0 %)。在豫西地区蛋鸡群中 ,致病性大肠杆菌的优势菌株应依次为O5,O8,O78,O14 1,O14 7,O18,其中O5,O8,O14 1,O14 7优势菌株的存在 ,足以说明豫西地区鸡大肠杆菌病的不同性和复杂性。药敏试验结果表明 ,所分离的大肠杆菌菌株对链霉素、烟酸氟哌酸抑菌作用最强 ,高敏菌株达 6 1 1%;次敏药物为蒽诺沙星、氯霉素、卡那霉素、畅乐、杆净 ;低敏和无抑菌作用的药物有痢特灵、土霉素和磺胺嘧啶。strains of Escherichia coli are isolated from 40 cases with yolk peritonitis,the rate of isolation is 90%.The results of serotyping identification shows that there are 9 serotypes in the isolated Escherichia coli,including O 5,O 8,O 78,O 141,O 147,O 18,O 19,O 14 and O 15 Among the serotypes,O 5,O 8,O 141 and O 147 are predominant and special.It suggests that Avian Colibacillosis in the west region of Henan province is very complicated.The results of antibiotics sensitivity test show that most of the isolated strains have high sensitivity to streptomycin and Fluoroquinolones,the sensitive strains are 61.1%.
