肺炎衣原体与急性呼吸道感染关系的探讨

Studying about the relationship between Chlamydia pneumonia and acute respiratory tract infection.

目的 探讨急性呼吸道感染与肺炎衣原体 (Cpn)感染的关系。方法 采用微免疫荧光方法对 10 9例急性呼吸道感染住院患者及 6 0例正常体检者分别进行Cpn血清学抗体检测。结果 10 9例呼吸道感染患者中检出Cpn阳性 41例 (38% ) ,血清学滴度IgG≥ 1:5 12或IgM≥ 1∶16判断为阳性 ,提示Cpn引起急性呼吸道感染。 6 0例正常对照IgG血清学滴度均小于 1∶5 12。

Objective To analyze the relation between Chlamydia pneumonia (Cpn)and acute respiratory tract infection. Methods All samples was tested for antibodies to Cpn specific antigen by Microimmunofluorescence (micro-IF). Results In 109 serum samples from acute respiratory tract infection patients, 41(38%)serum samples with micro-IF IgG titers equal to or greater than 1:512/and IgM titers equal to or greater than 1∶16 indicated recent infection .All serum titers of controls were smaller than 1∶512. Conclusion Infection of Cpn was one of the important pathogens for acute respiratory tract infection.
