Figure 4. Heatmap of ANI between CRC211 and 29 closely related S. oralis strains. The ANI value of 92.29% between CRC211 and S. oralis GCA_016028255.1 (arrow) confirms classification within the species while suggesting potential genomic divergence. Warmer colors represent higher sequence similarity. ANI: Average nucleotide identity; S. oralis: Streptococcus oralis.
