目的 :了解老年呼吸道感染患者病原菌的分布特点及药敏特性。方法 :对 2 88例老年呼吸道感染患者痰样本 (NC CLS法 )进行细菌培养 ,K B纸片法进行药敏测定。结果 :患者痰中共检出病原菌 4 0 0株 ,细菌 2 80株 ,其中G-杆菌 14 7株 ,占 36 .75 % ,G+ 球菌 133株 ,占 33.2 5 %。肺炎克雷伯菌及铜绿假单胞菌最敏感药的是头孢他啶 ,敏感率均为 4 0 %以上 ,肺炎链球菌和金黄色葡萄球菌最敏感药的是万古霉素 ;检出真菌 12 0株 ,占 30 % ,以白色念珠菌为主。结论 :进行病原菌跟踪监测及时的药敏试验 ,对及时控制老年呼吸道感染 ,是不可缺少的重要环节
Objective: To understand the distribution characteristics and drug sensitivity of pathogenic bacteria in elderly patients with respiratory tract infection. Methods: Bacterial culture was performed in 288 cases of elderly patients with respiratory tract infection (NC CLS method). Results: There were 400 pathogens and 280 bacteria in the sputum of sputum patients, of which 147 strains were G-bacteria, accounting for 36.7% and 133 strains were G + cocci, accounting for 33.2%. Klebsiella pneumoniae and Pseudomonas aeruginosa most sensitive drug is ceftazidime, the sensitivity rates were 40%, Streptococcus pneumoniae and Staphylococcus aureus is the most sensitive drug vancomycin; 120 fungi were detected , Accounting for 30%, mainly Candida albicans. Conclusion: It is an indispensable and important link to timely control of respiratory tract infection in elderly
