ABSTRACT
Objective@#To investigate the interaction between the gut microbiota and the sepsis in children by comparing the difference of gut microbiota between septic children and healthy children.@*Methods@#Genome was extracted from excrements of 18 cases of sepsis and 6 cases of healthy children.After genomic extraction, the hypervariable region of 16S rDNA gene were amplified and a small fragment library was constructed, and high-throughput sequencing was carried out, then the data of the lower machine was effectively sequenced by biological information processing.We could seek for the species that had changed significantly due to sepsis by comparing the diversity and the differences in the composition of intestinal flora between the two groups.@*Results@#The gut microbiome of the sepsis group was distinct from that of the health group.The operational taxonomic units in the sepsis group were significantly reduced compared with healthy group(P=0.001). The gut microbiome of children with sepsis had significantly lower diversity and richness compared with healthy group(P<0.05). A total of 7 species were shown to be differentially abundant between septic patients and healthy controls.The genus Pseudomonadales, Carnobacteriaceae and Granulicatella_elegans were significantly more abundant in the sepsis group; meanwhile the genus Pasteurellaceae, Ruminococcus, Lactobacillus_rogosae and Anaerostipes_butyratucus were less abundant in the sepsis group.In addition, the Granulicatella_elegans was characteristically present in the intestine of children with sepsis(P<0.001).@*Conclusion@#The microbial diversity and structure of the gut microbiome in children with sepsis are significantly different from those of healthy children.Our data suggest biomarkers identified in this study might participate in the pathogenesis or development process of sepsis.
