目的 :了解下呼吸道感染病原菌近期变化 ,制订防治策略。方法 :对我院近一年多来 40 0例下呼吸道感染病人的病原菌进行回顾性分析。结果 :G-杆菌 182株 ,占 45 .5 % ,其中绿脓杆菌、肺炎克雷伯杆菌、大肠埃希氏杆菌分别占 2 2 %、10 %、5 % ;G+球菌 111株 ,占 2 7.75 % ;霉菌 10 7株 ,占 2 6 .75 %。结论 :下呼吸道感染仍以 G-杆菌为主 ,但要注意 G+ 球菌及霉菌感染。
Objective: To understand the recent changes of pathogenic bacteria in lower respiratory tract and to develop prevention and cure strategies. Methods: The pathogenic bacteria in 40 0 cases of lower respiratory tract infection in our hospital in recent one year were analyzed retrospectively. Results: 182 strains of G-bacilli accounted for 45.5%, of which Pseudomonas aeruginosa, Klebsiella pneumoniae and Escherichia coli accounted for 22%, 10% and 5%, 111 strains of G + %; Mold 107 strains, accounting for 26.7%. Conclusion: Lower respiratory tract infection is still mainly G-bacteria, but pay attention to G + cocci and mold infection.
