Comparison of the salivary microbiota of the PSC, UC, and HC subjects. Samples from 24 PSC (red), 16 UC (green) and 24 HC (blue) subjects are shown. (A) The observed and the Chao 1-estimated OTU numbers, and the Shannon’s index of salivary microbiota from the three groups. (B) Weighted UniFrac-PCoA and (C) unweighted UniFrac-PCoA of salivary microbiota from the three groups. OTU, operational taxonomic unit; PCoA, principal coordinate analysis.
