儿童社区获得性肺炎大肠埃希菌耐药性分析

目的:研究本社区获得性肺炎(CAP)患儿感染大肠埃希菌的耐药情况,以指导临床合理使用抗生素,方法:采集我院2009年1月～2010年12月86株大肠埃希菌,纸片扩散法(K-B法)进行抗菌药物敏感实验.结果:86株大肠埃希菌耐药率,氨苄青霉素89.5%、复方SMZ 84.9%、阿莫西林克/拉维酸钾44.2%、哌拉西林/他唑巴坦10.5%、头孢呋辛41.9%、头孢噻肟55.8%、头孢曲松53.5%、头孢哌酮/舒巴坦12.8%、头孢吡肟30.2%、亚胺堵南2.3%、阿米卡星9.3%和左氧氟沙星16.3%.结论:本社区儿童社区获得性肺炎患儿中大肠埃希菌对氨苄青霉素、复方SMZ、阿莫西林,克拉维酸、头孢呋辛、头孢噻肟、头孢曲松、头孢吡肟等常用抗生素耐药率高,可首选哌拉西林/他唑巴坦、头孢哌酮/舒巴坦抗感染.

Analysis on drug resistance of Escherichia coli isolated from children with community acquired pneumonia

Objective:To study the antibiotics resistance of Escherichia coli isolated from children with community acquired pneumonia(CAP) in Manzhu area to instruct the reasonable use of antibiotics in clinic.Methods:A total of 86 strains of Escherichia coli were collected from the patients in our hospital during January 2009 to December 2010.The K-B method was used to determine the susceptibility of antibacterial drugs.Results:Total 86 strains of Escherichia coli were determined for the susceptibilities to antibioti...
