Fecal microbiome during episodes of bacteremia. (a) Relative abundance of bacterial species in pre-antibiotic fecal samples obtained prior to clinical evaluation resulting in the diagnosis of bacteremia. (b) Time course of relative abundance for the bacterial species matching those obtained from blood culture in each episode. Dashed lines indicate the days that antibiotics started and ended during each episode. Episodes E5 and E8 did not have post-antibiotic samples. The final sample in episode E7 was obtained prior to completion of therapy, as the infant was transferred to a different facility.
