儿童急性呼吸道感染肺炎衣原体感染状况的研究

Incidence of chlamydia pneumonia infection in acute respiratory infection in children.

目的 了解急性呼吸道感染儿童肺炎衣原体 (CPn)感染状况及特点。方法 采用敏感性较好的培养方法对 83例各年龄组呼吸道感染住院儿童进行了鼻咽拭子和咽拭子的培养分离。结果 共发现CPn阳性 2 1例 ,总感染率 2 5 3%。其中 49例肺炎中 ,CPn阳性 13例 (2 6 5 % ) ,10例毛细支气管炎中CPn阳性 2例 (2 0 % ) ,6例喘息性支气管炎中CPn阳性 1例 (16 7% ) ,12例上呼吸道感染中有CPn阳性 5例 (4 1 7% ) ,6例支气管炎中未分离到CPn。结论 CPn是我国儿童急性呼吸道感染的重要病原 ,其在儿童急性上呼吸道感染中占有主要地位 ,在毛细支气管炎、喘息性支气管炎中的作用值得重视。

Objective To investigate the prevalence and characteristic of chlamydia pneumonia(CPn)infection in acute respiratory tract diseases.Methods Nasopharyngeal and oropharyngeal swabs were cultured by comparatively sensitive method in 83 inpatients with all kinds of respiratory infection in children.Results In total of 83 respiratory infection inpatients,21(25.3%)were CPn positive.And among the CPn positive cases,13(26.5%)pneumonia,2(20%)brochiolitis,1(16.7%)asthmatic brochitis and 5(47.1%)upper respiratory infection.Conclusion CPn was an important respiratory pathogen in children with acute respiratory tract infection.And CPn played a major role in acute upper respiratory infection and pneumonia.The role that CPn plays in bronchiolitis and asthmatic brochitis deserves to be aware of.
