摘　　要：目的分析粪便标本分离的无活性大肠埃希菌的鉴定及耐药性。方法对该院2013年1月至2015年6月临床送检的粪便标本进行细菌培养、鉴定和药敏试验。结果共检出61株无活性大肠埃希菌,18株能与志贺菌诊断血清发生凝集反应。阿莫西林和替卡西林耐药率为100%,哌拉西林、头孢噻吩和复方磺胺甲噁唑耐药率为78%,头孢西丁和阿米卡星耐药率为33%,哌拉西林/他唑巴坦、亚胺培南和美罗培南耐药率为0%。结论无活性大肠埃希菌能引起腹泻,容易被误诊为志贺菌;耐药性与普通大肠埃希菌无显著不同。Objective To analyze the identification and antibiotic resistance of non active Escherichia coli isolated from feces.Methods Clinical fecal specimens were collected from January 2013 to June 2015 for bacterial culture,identification and antimicrobial susceptibility testing.Results Sixty-one strains of E.coli,inactive were detected,18 strains of which could be agglutinated with diagnostic serum of Shigella.Three stains could produce extented spectrumβ-lactamases（ESBLs）;The rate of antibiotic resistance of amoxicillin and ticarcillin was 100%,The rate of piperacillin,cephalothin and sulfamethoxazole was 78%,the rate of cefoxitin and amikacin was 33%,the rate of piperacillin/tazobactam,imipenem and meropenem was 0%.Conclusion Non active Escherichia coli can induce diarrhea,which is easily misdiagnosed as Shigella,the antimicrobial resistance between Escherichia coli and non active Escherichia coli is not significant difference.
