The gut microbiome is perturbed following occult colonization with K. pneumoniae. a Bray-Curtis principal coordinates analysis (PCoA) of microbiota at day 0 and day 7 post-gavage. N=28. b, c Volcano plots showing adjusted p value versus fold change of relative abundances of taxa at the b family and c species level between the 2 timepoints. d Relative abundance of Erysipelotrichaceae. Bars indicate mean abundance. Mock gavage with PBS served as the control. N=8. p values were calculated using a PERMANOVA or b–d paired Wilcoxon signed-rank tests with Benjamini-Hochberg correction. ***p value < 0.001
