  • a Standard errors are shown in the upper triangle. Values in parentheses are genetic distances based on 82 housekeeping genes extracted from genomes of 15 S. pyogenes strains, four S. dysgalactiae subsp. equisimilis strains (including SK1249 and SK1250 from this study), one S. dysgalactiae subsp. dysgalactiae strain, two S. equi subsp. zooepidemicus strains, and one S. equi subsp. equi strain. The strains are listed in Materials and Methods.
