一例印地安纳沙门菌致小儿败血症的鉴定溯源分析

Identification and infection source analysis of a case of pediatric sepsis caused by Salmonella Indiana

  • 摘要:
    目的对不明原因发热患儿外周血及粪便病原菌分离鉴定,明确感染病因。
    方法2018年9月9日,对浙江省嘉兴市第一医院接诊的1例发热患儿血培养及粪便培养的沙门菌进行血清分型和耐药、毒力基因(hilAssrAmgtCsiiDsopBspvC)检测及脉冲场凝胶电泳(PFGE)分型。
    结果患者外周血及粪便中病原菌为印地安纳沙门菌,携带hilAssrAmgtCsiiDsopB毒力基因,血流和粪便株PFGE聚类相似性为100%。
    结论该病例是印地安纳沙门菌引起的肠源败血症,应加强本地区基于实验室诊断的沙门菌血清型病例的监测能力。

     

    Abstract:
    ObjectiveTo identify and analyze the pathogens isolated from peripheral blood and stool samples of a child with fever of unknown origin in Jiaxing, Zhejiang province, and find out source of the infection.
    MethodsIdentification, serotyping and pulse field gel electrophoresis (PFGE) were performed for the pathogen strains isolated from peripheral blood and stool samples of the sick child. Polymerase chain reaction (PCR) was performed to detect the virulence genes (hilA, ssrA, mgtC, siiD, sopB, spvC).
    ResultsTwo pathogen strains isolated from peripheral blood and stool samples of the sick child were identified as Salmonella Indiana. The two strains carried virulence genes hilA, ssrA, mgtC, siiD and sopB, and the band similarity of two strains was 100% indicated by PFGE cluster analysis.
    ConclusionFever of this child was caused by the intestinal infection of S. Indiana, further resulting in sepsis. It is necessary to strengthen the laboratory based surveillance for S. Indiana in this area.
