儿童急性呼吸道感染肺炎衣原体感染状况的研究

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21例,总感染率25.3%.其中49例肺炎中,CPn阳性13例(26.5%),10例毛细支气管炎中CPn阳性2例(20%),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(41.7%),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.

Incidence of chlamydia pneumonia infection in acute respiratory infection in children

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.
