3岁以下小儿社区获得性肺炎细菌病原学监测分析

目的了解当地3岁以下小儿社区获得性肺炎(CAP)的细菌病原学流行情况。方法对2006年6月至2010年5月间3岁以下CAP住院患儿的细菌病原学监测资料进行回顾性分析。结果细菌总检出率为32.1%,其中金黄色葡萄球菌、大肠埃希菌、肺炎链球菌、肺炎克雷伯菌、阴沟肠杆菌占80.7%。金黄色葡萄球菌、肺炎链球菌、肺炎克雷伯菌和阴沟肠杆菌的检出与患儿年龄有关(P值均<0.05),金黄色葡萄球菌的检出与发病季节有关(P<0.05),金黄色葡萄球菌、肺炎克雷伯菌的检出与患儿来源有关(P值均<0.01)。结论当地3岁以下小儿CAP细菌病原学以金黄色葡萄球菌、大肠埃希菌、肺炎链球菌、肺炎克雷伯菌、阴沟肠杆菌为主,并受患儿年龄、发病季节、患儿来源影响。

The bacterial etiology pattern of community-acquired pneumonia in children under 3 years old in Yiwu area

Objective To investigate the bacterial etiology pattern of community-acquired pneumonia（CAP） in children under 3 years old in Yiwu area.Methods The pathogenic bacteria isolated from hospitalized children under 3 years old with CAP between June 2006 and May 2010 were retrospectively analyzed.Results Bacteria pathogens were determined in 649 of 2019 cases（32.1%）.The isolates of Staphylococcus aureas,Escherichia coli,Streptococcus pneumoniae,Klebsiella pneumoniae,and Eenterabacter cloacae accounted for 80.7%.The detection rates of Staphylococcus aureas,Streptococcus pneumoniae,Klebsiella pneumoniae,and Eenterabacter cloacae were associated with the age of children（P0.01,P0.05）.The detection rate of Staphylolcoccus aureas was associated with the season（P0.05）.The detection rate of Staphylolcoccus aureas,Streptococcus pneumoniae were associated with the source of children（P0.01,P0.05）.Conclusion The main pathegenic bacteria responsible for community-acquired pneumonia in children under 3 years old in Yiwu area includes Staphylolcoccus aureas,Eecherichia coli,Straptococcus pneumonias,Klebsiella pneumonias,and Eenterabacter cloacae and the isolation is related to the age,season,and source of children.
