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

    Graphical Abstract
    • 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.
