FIG 2.

Only patients with Escherichia coli infections showed differences in relative abundance between their stool and oral samples. Wilcoxon testing was performed on infectious agents of interest to determine if patients showed differing levels of abundance of their etiological agent between their stool and oral microbiomes. This was done by grouping patients by each infectious agent and plotting the relative abundance of the infectious agent in stool samples versus the relative abundance of the infectious agent in oral samples. The only set of patients that showed a statistically significant difference between samples were patients with E. coli infections.
