急诊病房下呼吸道感染病原菌及耐药性分析

目的 探讨急诊病房下呼吸道感染的病原菌分布及病原菌耐药性特征.方法 对2004年1月-2007年3月收治的267例下呼吸道感染患者痰培养的183株病原菌和药敏结果进行分析.结果 在检出的183株病原菌中革兰阴性菌占77.1%(以肺炎克雷伯菌为首位),革兰阳性球菌占22.9%(以屎肠球菌和金黄色葡萄球菌为首位);革兰阴性菌对庆大霉素、头孢唑林、复方新诺明、哌拉西林、环丙沙星、氨曲南总的耐药率高达60.5%～70.0%;对美罗培南、头孢吡肟、阿米卡星、亚胺培南、头孢哌酮/舒巴坦耐药率较低,为32.5%～38.6%;革兰阳性球菌表现出普遍较高的多药耐药性,对青霉素和红霉素100.0%耐药,但对万古霉素未发现耐药.结论 下呼吸道感染病原菌以革兰阴性杆菌为主,其中以肺炎克雷伯菌、屎肠球菌和金黄色葡萄球菌分别居革兰阴性菌和革兰阳性球菌的首位,表现出较高的多药耐药性.

Etiology and Drug Resistance of Lower Respiratory Tract Infection in Emergency Ward

OBJECTIVE To analyze the pathogens distribution and the antibiotic resistant characters.METHODS Sputum culture was performed in 267 cases who suffered from lower respiratory tract infection in emergency ward from Jan 2004 to Jun 2007.The results of 183 pathogens and drug sensitivity were analyzed.RESULTS The detected 183 strains of pathogens showed that Gram-negative bacilli accounted for 77.1%(Klebsiella pneumoniae was in the first place) and Gram-positive cocci were for 22.9%(Enterococcus faecium and Stap...
