To evaluate sputum culture and serology for detection of chlamydia pneumoniae (C. pneumoniae) in adult patients with acute respiratory tract infection and normal subjects.
Microimmunoflorescence (micro-IF) test for IgG and IgM antibodies to C. pneumoniae specific antigen was performed in every subject. Thirty-seven patients also had sputum HEP-2 cell culture tested for C. pneumoniae.
Twenty-six patients (29.7%) with micro-IF IgG titres equal to or greater than 1:512 or/and IgM titres equal to or greater than 1:32 indicated recent infection. Eight patients (21.3%) with positive sputum culture of C. pnuemoniae were identified. No similar titer was shown in control normal subjects.
Acute infection of C. pneumoniae was common in symptomatic patients with acute respiratory tract infection and attention should be drawn to this special illness.
评估痰培养和血清学检测在急性呼吸道感染成年患者及正常受试者中检测肺炎衣原体（C. pneumoniae）的情况。
对每位受试者进行针对肺炎衣原体特异性抗原的IgG和IgM抗体的微量免疫荧光（micro-IF）检测。37例患者还进行了痰HEP-2细胞培养以检测肺炎衣原体。
26例患者（29.7%）的微量免疫荧光IgG滴度等于或大于1:512和/或IgM滴度等于或大于1:32表明近期感染。8例患者（21.3%）痰培养肺炎衣原体呈阳性。对照正常受试者未显示类似滴度。
肺炎衣原体急性感染在有症状的急性呼吸道感染患者中很常见，应关注这种特殊疾病。
