摘要
目的:探讨我院外科常见细菌感染的菌株特点和细菌耐药情况。方法:按常规方法对2004—2006年送检标本进行细菌培养、分离、鉴定和药敏试验,进行统计学分析。结果:外科送检标本G+/G-细菌比例约为1∶3,G-中大肠埃希菌、铜绿假单胞菌、肺炎克雷伯菌占据所分离细菌前3位,G+细菌中金黄色葡萄球菌、屎肠球菌有较高的分离率,2006年外科屎肠球菌分离率显著高于全院水平。MRS、ESBLs、VRE的检出率分别为58.37%、32.67%和0,细菌对大多数抗菌药物的耐药性有逐年增高趋势。结论:G-细菌感染在外科细菌感染中仍占主要地位,屎肠球菌在外科送检标本中的比例提高应予以足够的重视。
Objective:To investigate the characteristics of bacterial distribution and drug resistance of surgical infection in recent two years.Methods:The samples of bacteria were cultured,isolated and identified.The drug sensitivity tests were proceeded by routine standards.Data were analyzed by statistics.Results:The ratio of germ positive bacteria and germ negative bacteria(G^+/G^-)was 1:3 approximately in surgical samples.Among the isolated bacteria from surgical specimen,escherichia coli,pseudomonas aeruginosa and Klebsiella pneumonia were the most common strains and marked as the 3 highest proportions in the study.There were higher proportions of staphylococcus aureus and enterococcus faecium in germ positive bacteria,especially in the year 2006,the identified rate of enterococcus faecium was significantly higher in surgical samples than that of whole hospital.The strains of MRS,ESBLs and VRE were detected 58.37%,32.67% and 0 respectively.The rates of drug resistant increased year after year.Conclusion:In surgical infection,the germ negative bacteria were the major pathogen.It should be paid attention that the more enterococcus faecium was found in surgical samples.
