摘要 目的了解下呼吸道感染病原菌分布和耐药性。方法收集2016年在杭州市富阳区第二人民医院门诊和住院治疗,咳痰伴发热或C-反应蛋白等细菌感染指标升高患者的痰标本,进行细菌培养、鉴定和药敏试验。结果共收集合格痰标本832份,经培养分离共得到457株菌株,其中革兰阴性菌401株,占87.7%,主要为铜绿假单胞菌和鲍曼不动杆菌;革兰阳性菌56株,占12.3%,主要为金黄色葡萄球菌。铜绿假单胞菌对四环素、阿莫西林/克拉维酸、头孢唑啉、头孢噻肟、氯霉素、氨苄西林和氨苄西林/舒巴坦等100%耐药,对多黏菌素的敏感性最高(98.4%)。鲍曼不动杆菌对大多数抗生素均有较高的耐药性。金黄色葡萄球菌对氨苄西林和青霉素100%耐药,未发现耐万古霉素和甲氧苄氨嘧啶的金黄色葡萄球菌。结论下呼吸道感染检出的病原菌种类以革兰阴性杆菌为主,对多数常用抗生素耐药。
