本文以间接血凝法对呼吸道反复感染儿(简称易感儿)50名及无呼吸道反复感染史的健康儿童131名进行血清支原体特异抗体的检测,结果发现具有诊断意义的阳性者共30名(总感染率为16.6%)、易感儿中肺炎支原体抗体阳性者19名(38%),对照组11名(8.4%),两组对比差异非常显著(T=22.9347,P<0.01),易感儿中有较高的肺炎支原体感染率。 In this paper, indirect hemagglutination of respiratory tract infection in children (referred to as susceptible children) and no history of respiratory tract infection in 131 healthy children with serum Mycoplasma specific antibodies were detected and found to have a positive diagnosis of a total of 30 The total infection rate was 16.6%). Among the susceptible children, 19 (38%) were positive for Mycoplasma pneumoniae antibody and 11 (8.4%) in the control group.
