Comparison of the gut microbiota between <i>P</i>. <i>gingivalis</i>-administered and sham-administered mice by 16S rRNA sequencing analysis (N = 6 in the experimental group, N = 7 in the control group).

<p>(A) Relative abundances of each bacterial group at the phylum level at 24 hrs and 48 hrs after <i>P</i>. <i>gingivalis</i> administration are indicated by box plots. (*<i>p</i> < 0.05, **<i>p</i> < 0.01, Mann-Whitney U-test). (B) Relative abundance of each bacterial group at the genus level were significantly increased or decreased are shown. Each assigned taxonomy obtained from 16S rRNA deep sequencing was compared to Silva database using UCLUST. (*<i>p</i> < 0.05, **<i>p</i> < 0.01, Mann-Whitney U-test).
