肺部感染病原菌及耐药性分析

目的了解我院肺部感染病原菌及耐药现状,为临床治疗应用抗生素提供依据。方法对我院185例肺部感染患者的痰标本进行细菌培养和菌种鉴定,并作药敏测定。结果 185例患者痰培养分离出病原菌共128株,其中G-杆菌占总菌株的82.1%,前四位菌种分别为大肠埃希菌、铜绿假单胞菌、鲍曼不动杆菌、肺炎克雷伯菌;药敏结果显示G-菌对抗生素的耐药率呈上升趋势。结论院内肺部感染的主要致病菌是G-杆菌,细菌耐药现象较为严重,临床上应加以重视并合理使用抗生素。

Analysis of lung infection pathogens and drug resistance

Objective To know the distribution and currence of drug resistance of lung infection pathogen in my hospital and to provide a basis of using antibiotics for clinical treatment.Methods 185 cases of pulmonary infection with sputum specimens for bacterial culture and strain identification,and determination of drug susceptibility.Results 128 strains were isolated and sputum cultured during 185 patients.G-bacteria accounted for 82.1%.The top four streins were Escherichia coli and pseudomonas,Acinetobacter bauman...
