[摘要] 目的 探讨老年住院患者社区获得性肺炎病原菌分布与耐药性。方法 方便选取该院103例老年社区获得性肺炎患者为研究对象，将其合格痰标本进行药敏试验及痰培养，对病原菌分布及耐药性进行分析。 结果 103例老年社区获得性肺炎患者共分离出致病菌130株，革兰阴性菌73株，占56.15%，前3位分别为铜绿假单胞菌、大肠埃希菌与肺炎克雷伯菌；革兰阳性菌57株，占43.85%，前3位分别为金黄色葡萄球菌、肺炎链球菌与溶血性链球菌。药敏实验结果显示，革兰阴性菌对头孢吡肟、左旋氧氟沙星、哌拉西林/他唑巴坦、多粘霉素、阿米卡星、亚胺培南的耐药性较低；革兰阳性菌对万古霉素、呋喃妥因、替考拉宁、甲氧苄氨嘧啶、复方磺胺等耐药性较低。结论 该院老年社区获得性肺炎患者以革兰阴性菌为主，且大多耐药程度高，通过病原菌耐药性监测，可提高临床用药合理性。
