    摘要:

    目的分析一对母婴同时携带的金黄色葡萄球菌的同源性,了解金黄色葡萄球菌在母婴之间传播的可能性。方法对分离的3株金黄色葡萄球菌(其中1株分离自受母乳喂养,患有脐炎的新生儿脐分泌物;另2株分别分离自该新生儿健康母亲左右两侧乳房分泌的乳汁)进行药敏试验表型分型和脉冲场凝胶电泳(PFGE)基因分型,分析其同源性。结果此对母婴携带的3株金黄色葡萄球菌对常用抗菌药物的药敏试验结果完全相同,PFGE图谱具有100%的相似度,PFGE结果聚类图处于同一分支。结论此对母婴携带的金黄色葡萄球菌是相同型别菌株,推测金黄色葡萄球菌在母婴之间传播的可能性大。

    Abstract:

    ObjectiveTo study the homology of Staphylococcus aureus (S.aureus) isolated from  a mother and her newborn,and to explore the possibility of transmission of S.aureus infection between mother and newborn.MethodsThree S.aureus isolates  from the umbilical secretion of a newborn with omphalitis and from the breast milk of the newborn’s healthy mother were performed  antimicrobial susceptibility testing,homology of S. aureus was analyzed through antimicrobial susceptibility testing phenotyping and  pulsedfield gel electrophoresis (PFGE) genotyping.ResultsThree S.aureus isolates from the mother and newborn had the same antimicrobial susceptibility pattern and PFGE type.ConclusionS.aureus isolated from the mother and newborn were identical strains,suggesting a possibility of S.aureus transmission between mother and newborn.
