Fig. 2

Sample types corresponding to oral (oral swab and dental plaque) and gut (feces) represented as body sites. a Bray–Curtis distances principal coordinate analysis for rodent samples. Each point corresponds to a sample colored by body site. Circle shapes show 95% confidence of the group. b Alpha diversity as richness showed statistical differences between sample types (P < 0.001, Wilcoxon test). c Beta-diversity using Bray–Curtis distances for the Human Microbiome Project samples showed differences between body sites. d Rat and human body site differences using pairwise PERMANOVA test for Bray–Curtis distances.
