泌尿系细菌L型感染病原菌分布及耐药性分析

目的探讨泌尿系细菌L型感染病原菌分布及耐药性，为临床合理选用抗菌药物提供依据。方法对188例次泌尿系细菌L型感染患者进行尿标本细菌培养及药敏试验，采用K—B法进行药物敏感试验。结果泌尿系细菌L型感染以革兰阴性杆菌为主，其次为革兰阳性球菌、真菌。其中大肠埃希菌居第1位，占37．77％，占革兰阴性杆菌的63．39％；其次，肠球菌属占16．49％，葡萄球菌属占9．57％，念珠菌属占8．51％。药敏试验显示，泌尿系细菌L型感染病原菌对多种抗菌药物产生了不同程度的耐药性，但革兰阳性球菌对万古霉素、大部分革兰阴性杆菌对亚胺培南敏感率为100．0％，鲍曼不动杆菌、克雷伯杆菌对亚胺培南呈不同程度耐药；产超广谱β-内酰胺酶（ESBLs）大肠埃希菌检出率是28．17％。结论泌尿系细菌L型感染病原菌以条件致病菌为主，且耐药性较为严重，应采取有效措施控制耐药菌的流行趋势。

The Distribution and Drug Resistance of Pathogenic Bacteria L in Urinary Infection

Objective To investigate the distribution and drug resistance of pathogenic bacteria L in urinary infection,and to provide the basis for clinical rational choose of antimicrobial agents.Methods Bacteria culture and drug susceptibility test with K-B method were performed among 188 samples from urinary tract bacteria L infection patients.Results Urinary tract infection with bacteria L was primarily negative bacillus,followed by Gram positive coccus,fungi.Among them,Escherichia coli accounted 37.77%,accounting...
