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%). These strains had the drug resistance to streptomycin,amoxicillin,sulfadimidine,ciprofloxacin,and ofloxacin. They could resist more than 5 kinds of drugs at the same time. These new strains were susceptible to the drugs such as cefo taxime, azithromycin, amikacin and cextrosulfenidol.关键词
