Abstract
In order to study the presence of antimicrobial resistance to Escherichia coli in chicken ,duck and goose in Jinzhou ,Liaoning province .A total of 302 E .coli strains ,isolated from chicken ,duck and goose (healthy and diseased animals ) ,were tested for resistance to 12 antimicrobials by micro-dilution method . The results showed that besides sensitive to amikacin and polymyxin B ,all the 302 isolates were differently resistant to the other antimicrobials ,and multi-drug resistance was serious .Except ampicillin ,streptomy-cin and ciprofloxacin ,E .coli isolates from chicken had a higher resistance rate to the other antimicrobials . Except ampicillin ,isolates from diseased poultries were markedly more resistant than those from normal poultries for the other 11 antimicrobial agents assessed .Despite some differences among species ,the w hole antimicrobial resistance to these three poultry E .coli was severe ,it’s necessary to strengthen the surveil-lance of antimicrobial resistance and give some directions to clinical medication .关键词
