摘　　要：目的:研究老年人肺部感染的细菌种类及其耐药情况。方法:对276例老年肺部感染患者的痰标本进行细菌培养和菌种鉴定,并作药敏测定。结果:老年肺部感染患者以G-杆菌居多(68.3%),肺炎克雷伯菌为最主要的致病菌;G+球菌其次(16.8%);霉菌占14.8%。药敏试验显示,大多数G-杆菌对广谱抗生素耐药。结论:老年人肺部感染的主要的致病菌是G-杆菌,真菌日渐增多,细菌耐药现象较为严重,临床上应加以重视并合理使用抗生素。Objective： To study the types of bacteria and drug resistance of the pulmonary infection in the elderly. Methods： 276 cases of pulmonary infection in the elderly patients with sputum specimens for bacterial culture and strain identification, and determination of drug susceptibility. Results： The elderly patients with lung infection in most G^- bacilli （68.3%）,Klebsiella pneumoniae as the most important pathogens. G^＋ cocci followed （16.8%）. Streptomyees accounted for 14.8%. Sensitivity test showed that the majority of G^- bacilli to broad-spectrum antibiotic resistance. Conclusion： The elderly lung infections are the major pathogens in G^- bacteria, fungi increasing and bacterial resistance is more serious, the clinical importance should be on the rational use of antibiotics.
