文档介绍：小儿肺炎细菌病原学分析
[摘要] 目的探讨小儿肺炎的细菌病原学分布特点,以期更好地指导临床用药。方法对2009年10月~2011年10月于我院住院的126例小儿肺炎患儿常规深部痰培养,并进行细菌学检测。结果 126例患儿检出细菌68株,%(68/126)。其中革兰阴性(g—)菌55株(%,55/68),肺炎克雷伯肺炎亚种及大肠埃希菌居前,%(18/68)%(14/68);检出革兰阳性(g+)菌13株(%,13/68),%(6/68)。结论小儿肺炎致病菌中以g—菌为主,肺炎克雷伯肺炎亚种、大肠埃希菌及金葡菌是该地区小儿肺炎的主要细菌病原菌。

[abstract] objective to summarize the distribution of children bacterial pneumonia, and provide a clinical basis for the therapy, diagnosis of bacterial pneumonia. methods between october 2009 and october 2010, 126 patients with pneumonia were enrolled. respiratory tract secretion for micro biological investigation was obtained by vacuum suction. results the total positive rate was % (68 of 126 strains), gram—negative bacteria (55 strains, %) and gram—positive bacteria (13 strains, %) mainly including us aureus. conclusion the main species of pathogens causing pneumonia are gram—negative bacteria, mainly including pneumonia cray, subspecies and escherichia coli, and us aureus.
