目的 了解呼吸道感染患者肺炎衣原体感染状况,为临床诊断和治疗提供依据.方法 用ELISA方法对呼吸道感染患者血清进行肺炎衣原体血清抗体IgG和IgM的检测,结果采用SPSS 10.0软件包进行数据统计分析,计数资料比较用x2检验.结果 91例呼吸道感染患者肺炎衣原体抗体IgG阳性者为58例,阳性率为63.7％；IgM阳性者为9例,阳性率为9.9％.男性和女性IgG和IgM阳性率均无统计学差异.＜40岁组和≥40岁IgG阳性率分别为52.5％和86.7％,两者具有统计学差异；IgM阳性率分别为4.8％和14.3％,无统计学差异.结论 在有呼吸道症状的病例中,肺炎衣原体感染率较高,应对肺炎衣原体感染加以重视.%Objective To investigate Chlamydia pneumoniae infection in patients with respiratory tract infection and provide information for clinical diagnosis and treatment. Methods ELISA was used to detect Chlamydia pneumoniae antibodies in sera of patients with respiratory tract infection. SPSS software and X2 test were used to analyze the results. Results Totally 91 sera from patients with respiratory tract infection were collected. 58 were positive for IgG and the positive rate for IgG was 63.7% . 9 patients were positive for IgM and the positive rate for IgM was 9. 9% . No significant difference was observed in IgG and IgM positive rate between men and women. The positive rate of IgG in more than 40 - year - old group and less than 40 - year - old group was 52. 5% and 86. 7% respectively. The difference in positive rate of IgG was significant between two groups. The positive rate of IgM in more than 40 - year - old group and less than 40 - year - old group was 4. 8% and 14. 3% respectively. The difference in positive rate of IgM had no significance between two groups. Conclusion There are higher Chlamydia pneumoniae infection rate in patients with respiratory tract infection. Chlamydia pneumoniae infection should be taken seriously.
