尿路感染大肠埃希菌耐药分析

目的:探讨尿路感染大肠埃希菌的耐药性变迁,为临床合理用药提供试验依据.方法:对2008～2010年度尿标本检出的234株大肠埃希菌进行超广谱β-内酰胺酶(ESBLs)检测和药敏试验,并对药敏结果进行分析.结果:大肠埃希菌的产酶率呈增高趋势;药敏结果显示大肠埃希菌除对亚胺培南耐药率为0外,对其他常用抗菌药物均出现了不同程...

The analysis of drug resistance of Escherichia coli in urinary tract infections

Objective：To explore the resistance changes of Escherichia coli（E.coli） in urinary tract infection,and provide proofs about the reasonable use of drugs in clinic.Methods：Two hundred and thirty-four strains of E.coli in 2008 to 2010 annual urine specimen with extended-spectrum β-lactamase（ESBLs） detection and drug susceptibility test were detected,and the drug susceptibility results were analyzed.Results：The rate of enzyme production of E.coli showed a rising trend;the drug sensitivity test showed that the resistance existed in normal antibiotics was in different degrees except for Imipenem,and the rate of medical resisitance in ESBLs（＋） bacteria was higher than in ESBLs（-）.Conclusions：The resistance of urinary tract infection which caused by E.coli especially in ESBLs（＋） strains is so serious.It should be strengthen in the detections of the medical resistance,which provide the references for the clinic rational drug use.
