Comparison of the salivary microbiotas. A. Hierarchical clustering trees were generated using unweighted UniFrac based on the presence or absence of all 3011 phylotypes (All) defined at 100% identity or subsets including indicated phylum or order Clostridiales. The trees based on 583 phylotypes defined at 97% identity and their derivatives obtained by the removal of hypervariable regions are designated All OTU003, and All OTU003-hv, respectively. Clusters formed by the three time points of the same subject are colour-shaded. PCoA analysis based on unweighted (B) or weighted (including abundance) UniFrac and 100%-ID phylotypes (C). Samples from the same subject are represented by the same colour.
