Pathogenic bacteria of human periodontitis are enriched in the ligature silk in the mouse model. Bacterial community of ligature silks from Sham, LIP, and LIP + SP group mice were analyzed using 16S rRNA gene sequencing. (A) α-diversity of bacteria on ligature silks assessed by Chao1 and Shannon indices. (B) β-diversity of bacteria on ligature silk assessed by principal coordinate analysis (PCoA) based on Bray–Curtis distance of bacteria at species level. (C) The heat map of the relative abundance of the top 20 most abundant species of bacteria on ligature silks. (D) Taxonomic cladogram of bacteria on ligature silk using LEfSe (LDA = 3.59). The values represent means ± SEM (n = 3:5:5). **P < 0.01.
