Characteristics of the intestine microbiome in BSI and non-BSI patients. a Analysis of non-metric multidimensional scaling (NMDS) of samples from BSI and non-BSI groups at family level. b Shannon diversity at the phylum, family, genus, and species levels c Stacked column charts of the relative abundance of the top 10 phyla, families and genera. The red and blue boxes represented a significant increase and decrease in relative abundance in the BSI group, respectively, compared with the non-BSI group d Boxplot of relative abundance at species level. The student’s t-test was used for data with a homogeneous variance; otherwise, the Mann–Whitney test was used. Multiple groups were compared using one-way ANOVA
