Abundance of the BSI-causing species (A) S. aureus, (B) S. agalactiae, (C) E. faecalis, (D) S. marcescens, (E) Klebsiella spp., and (F) E. coli in the gut microbiome before BSI onset shown for those with BSI from that organism versus from all others. Generalized LME models were used with MaAsLin2 and controlled for DOL and participant with Benjamini-Hochberg–corrected false discovery rate q value. ”Yes” indicates bacteremia from that organism, and “No” indicates absence of bacteremia from the listed organism but could include bacteremia from other organisms. Stools after BSI for participants in the “yes” category were not included in this analysis.
