Figure 2: Mean number of OTUs (A) and shannon index (B) in the salivary microbiome of 50 Thai children from 5 geographical groups. The error bar indicate 95% confidence intervals. Two indices of alpha diversity indicate that salivary bacterial communities of the East group are more diverse compared to those of the South and West groups (P <0.05). OTUs: operational taxonomic units.
