临床常规分离细菌2016株耐药情况分析

目的:研究分析我院微生物实验室2004年1月~2005年10月分离细菌分布及耐药情况。方法:收集我院2004年~2005年临床分离菌共2016株,并对其进行抗菌药物敏感试验,并用WHONET-4软件进行耐药性分析。结果:革兰氏阳性菌645株(占32.0%),分离率占前四位的分别是凝固酶阴性葡萄球菌占15.6%,金黄色葡萄球菌占6.3%,粪肠球菌占4.2%,屎肠球菌占1.5%。革兰氏阴性菌1371株(68.00%),分离率占前五位的分别是大肠埃希氏菌占16.8%,铜绿假单胞菌占13.6%,阴沟肠杆菌占5.2%,鲍曼氏不动杆菌占4.9%,肺炎克雷伯菌占4.6%。革兰氏阳性菌总体上对万古霉素耐药性最低0.8%,对青霉素耐药性最高82.0%。革兰氏阴性菌对亚胺培南的耐药性最低6.2%,其他的依次为头孢哌酮-舒巴坦8.14%,头孢他啶23.3%,阿米卡星27.8%。革兰氏阳性菌中耐甲氧西林凝固酶阴性的葡萄球菌百分率较高占68.6%。结论:我院临床标本中分离的细菌的耐药问题比较严重,微生物实验室需加强细菌耐药性监测,以帮助临床医生合理使用抗菌药物及有效控制细菌感染和耐药性的播散。

Analysis of Resistance in 2106 Bacterial Strains

Objective To identify bacteria from the Central,Hospital of Shaoyang Hunan and its resistance to antibioties.Methods We collected 2016 strains and tested bacterial resistance to antibioties with WHONET-4 software.Results There were 645 strains gram positive cocci(32.0%)and 1371 strains gram negative bacilli(68.0%).Gram positive cocci resistance to vancomycin was lowest in all antibioties.Conclusion There is little serious situation of bacteria resistance to antibioties in our hospital. Microbiological laboratories must detect the resistant bacteria rapidly,so as to control the dissemination of bacterial infection and its resistance.
