Fig. 5: Distribution of Streptococcus clades in modern oral samples of calculus, dental plaque, buccal mucosa, and saliva.

A Percent of Streptococcus reads that were assigned to each clade out of all reads assigned to Streptococcus, ordered by decreasing abundance of Sanguinis clade and increasing abundance of Mitis clade. B Percent of reads assigned to species in the genus Streptococcus and to all other genera. C Percent of reads assigned to species in the Sanguinis, Mitis, and Anginosus clades out of all species-level read assignments.
