两种检测急性呼吸道感染患儿肺炎支原体方法的比较

Analysis of the two methods of detection of infection Mycoplasma pneumoniae children

目的分别以咽拭子培养肺炎支原体与血清肺炎支原体抗体(MP-IgG、MP-IgG)检测急性呼吸道感染,为早期诊断小儿感染肺炎支原体提供参考。方法记录咽拭子液体培养肺炎支原体、MP-IgG、MP-IgG结果并加以统计分析。结果肺炎支原体液体培养阳性率63.6%,MP-IgM阳性率为32.8%,MP-IgG阳性率为22.1%。结果显示咽拭子液体培养法阳性率与血清特异性抗体MP-IgM、MP-IgG的阳性率比较,差异均有统计学意义(P<0.05)。结论咽拭子液体培养法可早期和有效检测肺炎支原体感染。

Objective To detect the infection of Mycoplasma pneumoniae by the throat culture of Mycoplasma pneumoniae and serum Mycoplasma pneumoniae antibodies（MP-IgG and IgM） for finding a method to diagnose the MP infection in early stage in children. Methods Throat cultures of Mycoplasma pneumoniae and serum antibodies of Mycoplasma pneumoniae（MP-IgG,IgM） were detected and statistical analysed in Infection Mycoplasma pneumoniae children. Results The positive rates of Mycoplasma pneumoniae culture,MP-IgM and MP-IgG were 63.6% ,32.8% and 22.1%, respectively. There were significant differences between them. Conclusion Throat swab liquid culture can be the early and sensitive detection of Mycoplasma pneumoniae infection.
