【摘要】 目的 探讨老年患者肺部感染病原菌的分布及耐药现状。 方法 对236例老年肺部感染患者进行细菌学培养和药物敏感试验。 结果 老年社区获得性肺炎患者的病原菌以G + 球菌为主，占65.38%。以肺炎链球菌(23.08%)和流感嗜血杆菌(15.38%)为主;老年医院获得性肺炎患者的病原菌以G - 杆菌为主，占77.78%。以铜绿假单胞菌(27.78%)、大肠杆菌(14.81%)和肺炎克雷伯菌(11.11%)为主。两组病原菌对多种抗生素耐药性较高，医院获得性组的耐药率明显高于社区获得性组。 结论 老年患者社区获得性肺炎和医院获得性肺炎分别以革兰阳性球菌为主和革兰阴性杆菌为主，医院获得性肺炎细菌耐药性明显增高，应合理选用抗生素。
