母婴垂直传播的新生儿肺炎的病原菌分析

Analysis of pathogenic bacteria of neonatal pneumonia caused by vertical transmission of maternal and infant children

目的了解并分析由母婴垂直传播引起的新生儿肺炎的病原菌的情况。方法以2016年1-12月入住我院新生儿科的肺炎患儿为研究对象,取咽拭子进行解脲支原体(UU)和B群链球菌(GBS)培养,对结果进行分析并与母亲的检测结果比较。结果共检出78(11.3%)例阳性,其中解脲支原体18例(23.1%),人型支原体2例(2.6%),解脲支原体和人型支原体混合感染5例(6.4%),GBS感染53例(67.9%)。患儿咽拭子分离的病原菌及病原菌的药敏谱同母亲生殖道分离的基本一致。结论应重视孕产妇妊娠期间UU和GBS的筛查,且对于曾有UU或(和)GBS感染的孕妇应在分娩后对新生儿的咽喉部分泌物进行UU和GBS检测,以降低母婴垂直传播病原体引起的新生儿肺炎的发生率并根据药敏结果及早进行防治,利于优生优育工作的开展。

Objective To analyze the pathogenic bacteria of neonatal pneumonia caused by vertical transmission of maternal.Methods Pharyngeal swabs from the newborn with pneumonia hospitalized in neonatal department of our hospital from January 2016 to December 2016 were used for the culturing and detection of urea mycoplasma(UU)and group B treptococcus(GBS).The results of the culture and drug susceptibility were analyzed and then compared with the mother′s test results.Results A total of 78 cases(11.3%)were detected positive,18(23.1%)positive with urea mycoplasma,5(6.4%)with urea mycoplasma and mycoplasma hominis,53(67.9%)with GBS.The pathogens and the drug susceptibility spectrum of pathogenic bacteria from pharyngeal swabs were the same as the mother′s genital tract.Conclusions Screening of UU and GBS in maternal pregnant women should be paid much attention.In order to reduce maternal and infant vertical transmission of pathogens causing the incidence of neonatal pneumonia and provide early prevention according to the result of drug susceptibility,pharyngeal swabs from newborns delivered by the pregnant women infected with UU&or(and)GBS should be collected for UU and GBS detection,which is conducive to the development of the prenatal and postnatal care.
