Fig. 6: Relative abundance of Sanguinis and Anginosus clade species in tooth-adherent oral microbiome samples.

Color scale is log10 of the percent relative abundance. A Ancient dental calculus. Sample order is identical to Fig. 2. B Modern dental calculus and modern dental plaque. Sample order is identical to Fig. 5. C Difference in the breadth of coverage (minimum 1X depth) of S. sanguinis and S. sinensis genomes in ancient dental calculus and modern non-industrial dental plaque. Shapes indicate the Streptococcus species that was most abundant in each sample based on profiling with Kraken2 using the GTDB r202 database.
