摘要
目的了解我院两年来呼吸内科下呼吸道致病菌株的分布及耐药情况。方法获得纯培养后,经VITEK-AMS系统鉴定共分离出315株致病菌,药敏试验采用VITEK-AMS系统药敏卡。结果革兰阴性杆菌占68.9%,真菌占18.7%,主要致病菌依次为绿脓假单胞菌23.5%,不动杆菌属10.2%,肺炎克雷伯菌9.5%,大肠埃希菌7.9%。金黄色葡萄球菌6.0%。药敏结果表明:细菌耐药现象严重,对环丙沙星总敏感率最高。结论下呼吸道细菌感染性疾病中仍以革兰阴性杆菌为主,真菌检出率增高,产ESBLs和耐甲氧西林菌株明显增多,今后应提示临床加强病原菌培养及药敏检测,以指导临床科学使用抗生素。
Objective To understand distribution and drug resistance of lower respiratory tract in Department of Respiratory Medicine in our hospital in Iast two years.Methods Afterpure culture was obtained,315 strains of pathogenic bacteria were separated by identification using VITEK-AMS system.VITEK-AMS system drug sensitive card was used for drug sensitive test.Results Gram-negative bacilli auounted for 68.9%,Fungi accounted for 18.7%,Themajor pathogenic bacteria were in order:pseudomonass aeruginosa 23.5%,Acinebacter 10.2%,kiebsiella pneumoniac 9.5%,Escherichia coil 7.9%,staphylococcus aureus 6.0%.the drug Semsitive test showed that bacteria had serious drug resistance and ciprofioxacin had the highest total sensitive rate.Conclusion Among bacterial infections in lower respiratory tract,gram-negative bacilli were major,fungi detectable rate increased.Strain producing ESBLs and resistant to methicillin increased.From now on pathogenic bacteria culture and drug SEnsitive test shluld be enhanced to guide clinical staff on conrrectn use of antibiotics.
