随着抗生素及免疫抑制剂的广泛应用 ,老年人呼吸道感染的病原菌分布已有了明显变化 ,耐药菌株不断增加。本文收集了 1996～ 1998年间老年患者呼吸道感染症痰培养病原菌 2 0 4株 ,及其对常用抗生素的耐药性进行了调查 ,并与我院同期临床分离菌株构成比例进行对照 ,对耐药率进行 With the widespread use of antibiotics and immunosuppressive agents, the distribution of pathogenic bacteria in respiratory tract infections in the elderly has changed significantly, and drug-resistant strains have continued to increase. This article collected 204 sputum culture pathogens of respiratory infections among elderly patients from 1996 to 1998 and their resistance to commonly used antibiotics. It was compared with the proportion of clinical isolates in our hospital during the same period. get on
