From: Defining the healthy "core microbiome" of oral microbial communities
The extent of overlap of oral microbiome between three individuals. The extent of overlap between subjects S1 (pink circle), S2 (light blue circle) and S3 (yellow circle) at the level of A) unique sequences, B) OTUs clustered at 3% difference and C) higher taxa (genus or more inclusive taxon). The data was obtained by combining all samples of the respective individual microbiome. The Venn Diagrams show that 26% of the unique sequences, 47% of the OTUs and 72% of the higher taxa were common (area in grey) to the three individuals.
