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。

Abstract: | 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 antimicro-bial 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 spectrum β-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 . |
