【摘要】 目的 :通过对 2 0 0例老年 ( >6 0岁 )呼吸道感染患者病原菌的动态监测及药敏试验 ,为临床合理选择抗菌药物提供参考。方法 :收集患者晨痰 ,分离鉴定病原菌 ,K B法进行药敏试验 ,按NCCLS标准判断结果。结果 :老年呼吸道感染细菌以G- 杆菌为主 ,占 81.2 % ( 12 5株 )。G+ 球菌感染率较低 ,仅占 18.8% ( 2 9株 ) ,真菌感染率较高 ,占总菌珠的 4 8.8% ( 14 7珠 ) ,细菌变迁较大。结论 :病原菌动态监测及药敏对临床治疗起关键作用。更多还原

【Abstract】 Objective: To offer reference for selecting effective antibacterial drugs in the clinic treatment through dynamic monitoring the pathogenic bacterium of 200 aged patients with respiratory tract infection(about sixty years or older) and drug susceptibility test.Methods: The sputum from patients was collected and monitored .The pathogenic bacteria in the sputum separated and identified.The drug susceptibility test was used by K B method and the results were judged according to NCCLS.Results: The major pathogenic bacteria in old respiratory tract infection were gram negative bacteria,the infection rate was about 81.2%(125strains).The infection rate of gram-positive bacteria was about 18.8%(29 strains).The fungus infection rate was higher about 48.8%(147 strains).The bacteria variance is very quick.Conclusion:A dynamic monitoring and drug susceptibility to pathogenic bacterium play an important role in the clinic treatment.更多还原
