  1. 1Index of association based on one strain per ST: IA: calculated using classical Maynard Smith approach, IA S: standardized according to Haubold
  2. 2SBSEC: includes also 3 S. gallolyticus subsp. pasteurianus and 1 S. alactolyticus strains not listed separately
  3. 3 A allele
  4. 4 Pms polymorphic sites
  5. 5SID (95 % CI): Simpson’s index of diversity with 95 % confidence interval (CI) calculated from SID+/− 2*Standard deviation
  6. 6no dN/dS calculation due to limited allele numbers and differences
  7. Values were calculated for the entire SBSEC and individual (sub)species, including all 10 target genes and Simpson’s index of diversity (SID) as an indication for the differentiation power among strains
