288例老年呼吸道感染患者病原菌分布特性及药敏分析

Distributing Characteristic of Pathogens Bacteria and Analysis of Drug Susceptibility in 288 Senile Patients with Respiratory Tract Infection

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 。

Objective: To investigate the distributing characteristic of pathogenic bacteria in senile patient with respiratory tract infection and thd drug susceptibility.. Method: The pathogenic bacteria were dedected in 288 senile patients with respiratory tract infection according to NCCLS and the drug susceptibility was determined by K B paper method. Result: 400 strains of pathogenic bacteria were identified of which, 147( 36.75% )strains were G - bacteria, 133 strains ( 33.25% ) were G + bacteria. More than 40% of Klebsiella pneumoniae and Seudomonas Staphylococcus aureus were sensitive to ceftazidime. The Pneumonitis streptococcus and Staphylococcus aureus were still sensitive to Vancomycinum. 120 strains (30%) of fungus were identified at same time with mainly white candidiasis.Conclusion: It is important to track pathogenic bacteria and conduct the test of drug susceptibility for controlling the respiratory tract infection of senile patients in time.
