Venn diagram showing the taxonomic classifications of some of the core OTUs present within ≥95% of the samples in the indicated subsets of oral sites. For example, Bulleidia moorei was found in ≥95% of tongue plaque and saliva samples, but <95% of supragingival plaque samples, while Rothia dentocariosa was found in ≥95% of the samples from all three sites.
