江油地区儿童社区获得性肺炎病原学分析

Analysis on the etiology of acquired pneumonia of children community in Jiangyou ared

目的了解江油地区社区获得性肺炎病原体分布情况,为经验治疗提供依据。方法对1 995例大于或等于2岁的社区获得性肺炎患儿留取呼吸道分泌物进行细菌培养,同时采用聚合酶链反应检测非典型病原体。结果 1 995例患儿病原学检测阳性426例(21.35%),其中常见细菌阳性324例(16.24%),病原菌中以肺炎链球菌为主,其次为阴沟肠杆菌、肺炎克雷伯菌及肺炎克雷伯菌。非典型病原体102例(5.11%),包括肺炎支原体、细菌合并肺炎支原体感染及肺炎衣原体等。结论肺炎链球菌是江油地区社区获得性肺炎的主要致病菌。

Objective To understand community-acquired pneumonia pathogens distribution,and to provide basis for the experience treatment in Jiangyou area.Methods Bacterial culturing of respiratory secretions was performed in 1 995 cases（≥2 years） of community-acquired pneumona,meanwhile,polymerase chain reaction（PCR） was used to detect the atypical pathogens.Results 426 out of 1 995 cases were pathogen positive（21.35%）,including 324 cases of common bacteria positive（16.24%）.Pathogenic bacteria was mainly Streptococcus pneumonia,followed by Enterobacter cloacae,Klebsiella pneumoniae and Klebsiella pneumoniae.There were 102 cases of atypical pathogens（5.11%）,including Mycoplasma pneumoniae,Mycoplasma pneumoniae infection and combined bacteria Chlamydia pneumoniae.Conclusion Streptococcus pneumoniae is the main pathogenic bacteria of community-acquired pneumonia in Jiangyou area.
