呼吸道感染病原菌分布及耐药性分析

目的 了解呼吸道感染患者的病原菌分布及其耐药性,指导临床合理用药.方法 回顾性分析2005年1月～2007年6月住院呼吸道感染患者痰培养结果.结果 2 100株病原菌G-菌占75%、G 菌占15%、真菌占10%.以铜绿假单胞菌、鲍曼不动杆菌、大肠埃希氏菌、金黄色葡萄球菌和肺炎克雷伯氏菌为主要细菌,革兰氏阳性球菌对万古霉素、米诺环素和利福平较为敏感,而革兰氏阴性杆菌对美洛培南、亚胺培南和阿米卡星的敏感性较高.常见G 、G- 菌的耐药性有上升趋势,且具有多重耐药性.结论 在治疗感染性疾病时应进行病原学检查,依据药敏试验结果合理使用抗生素,以减少耐药菌株产生.

Investigation and Analysis on Pathogens in Respiratory Tract Infection in Inpatients

Objective To investigate the pathogenic change in respiratory tract infection(RTI) in inpatients and to provide reference for clinical treatment. Methods Retrospective analysis was conducted on sputum cultivation results of RTI patients who were hospitalized from January 2005 to June 2007.Results 2 100 strains were isolated from 6 800 samples,positive rate was about 31%.Gram-positive microorganisms accounted for 15%(315) of the positive culture results,Gram-negative microorganisms accounted for 75%(1 475),a...
