本文应用聚合酶链反应（ＰＣＲ）技术检测了１５６例喘息性疾病患儿咽拭子标本的肺炎支原体（ＭＰ），阳性率为１２．２％，对照组为同期３８例肺炎患儿的咽拭子标本，ＭＰ阳性率为１７．３％，二组ＭＰ感染率无显著性差异（ｘ２＝１．７７，Ｐ＞０．０５）。提示：ＭＰ不仅是肺炎也是喘息性疾病患儿常见的致病微生物。因此，对喘息性疾病患儿应常规用ＰＣＲ技术检测ＭＰ，以提高诊断和治疗水平
Mycoplasma pneumoniae (MP) was detected in throat swabs of 156 children with wheezing diseases by polymerase chain reaction (PCR), the positive rate was 12.2%. The control group was 38 The positive rate of MP in sub-specimens was 17.3%. There was no significant difference in MP infection rate between two groups (x2 = 1.77, P> 0.05). Tip: MP is not only a common pathogenic microorganism in children with pneumonia but also wheezing diseases. Therefore, children with wheezing should be routinely detected by PCR PCR technology to improve the diagnosis and treatment
