Abstract

Abstract: In order to grasp the resistance of E. coli to common antibiotics in Wuhan district, the suspected diseased chicken samples were collected for E. coli isolation and identification, and the drug isolates were analyzed for drug sensitivity.The results showed that 55 strains of E. coli were isolated from 115 samples from 11 farms in Wuhan, and their resistance rates to penicillin （P） and ampicillin （AMP） reached 100%; for cefradine （CED） and streptomycin （STR）, chloramphenicol （C）, florfenicol （FFC）, tetracycline （TET） resistance rate of more than 80%; for cefepime （FEP）, gentamicin （GEN）, levofloxacin （LEV）. The most sensitive, the resistance rate is less than 10%. There were 12 drug resistance profiles in 55 strains of E. coli, and the multi-drug resistance rate was as high as 94.55%, among which 3 resistant strains accounted for 50.91%.

Key words: avian, Escherichia coli, isolation and identification, drug resistance pattern
