小儿肺炎细菌病原学分析

The distribution of children bacterial pneumonia

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．检出率53．97％（68／126）。其中革兰阴性（G-）菌55株（80．88％，55／68），肺炎克雷伯肺炎亚种及大肠埃希菌居前，分别占26．47％（18／68）及20．59％（14／68）；检出革兰阳性（G＋）菌13株（19．12％，13／68），检出率较高的为金葡菌8．82％（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,＇bJL肺炎的主要细菌病原菌。

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 pneumo- nia were enrolled. Respiratory tract secretion for micro biological investigation was obtained by vacuum suction. Results The total positive rate was 53.97% （68 of 126 strains）, Gram-negative bacteria （55 strains, 80.88%） and Gram-positive bacteria （13 strains, 19.12%） mainly including Staphylococcus aureus. Conclusion The main species of pathogens causing pneu- monia are Gram-negative bacteria, mainly including Pneumonia Cray, subspecies and Escherichia coli, and Staphylococcus aureus.
