泌尿系感染细菌的分布及耐药性比较

目的：探讨尿路感染患者病原菌的耐药性及其分布情况,为临床合理用药提供依据。方法：回顾性分析2008年2月～2010年2月我院410例确诊为尿路感染患者的尿液标本,对其病原菌的耐药性及分布情况进行统计分析。结果：革兰阴性杆菌占54.63%,其中以大肠埃希菌为主,占39.76%;革兰阳性菌占35.85%;真菌占9.51%。药敏结果：大肠埃希菌对氨苄青霉素的耐药率最高为96.20%,而对亚胺培南敏感率最高为100.00%;革兰阳性菌对多数抗生素有不同程度耐药。结论：大肠埃希菌仍然是尿路感染的主要致病菌,但革兰阳性菌、真菌等有增多趋势。致病菌对临床多数抗菌药物耐药率较高,临床应根据药敏结果合理用药。

Pathogenic bacteria distribution and drug resistance of urinary infection

Objective: To determine the distribution of pathogens and their resistance characteristic in urinary infection in order to provide the basis for the clinician to select antibiotics correctly.Methods: Total 410 clinical isolates of cases of urinary tract infection were collected from patients cured in our hospital from Feb.2008 to Feb.2010.The kinds of isolated bacteria and their sensitive rates were analyzed.Results: Among 410 strains Gram-negative bacilli accounted for 54.63%(the most was Escherichia coli ...
