| 摘 要： | 为掌握开封地区鸡大肠杆菌的耐药性情况,对来自开封地区疑似鸡大肠杆菌病的12份病料进行病原菌的分离鉴定、形态学观察、生化试验,并对分离株进行了动物接种试验和耐药性分析,结果鉴定出6株鸡大肠杆菌.动物攻毒试验结果显示,6株细菌对雏鸡的发病率均为100％,致死率各不相同.其中KF株对雏鸡的致死率最低,为50％(10/20) ...

| Abstract: | In order to investigate the drug tolerance of chicken Escherichia coli(E.coli) in Kaifeng area,identification,morphology observation,biochemical test,animal experiments and the drug tolerance analysis of the isolates from 12 suspected chicken colibacillosis specimens were performed.Finally,a total of 6 isolates were characterized as E.coli and all showed 100% morbi-dity but different fatality to chicken,among which KF strain showed the lowest fatality(50%) while LK strain showed the highest fatality(90%).Th... |
