Figure 2.
Phylogeny of EMRSA-15 and distribution of antibiotic resistance genes. The maximum likelihood tree of ST22-A isolates was based on core SNPs identified by mapping to the reference ST22 genome HO 5095 0412. The total number of SNP sites present in the core genome alignment in this lineage was 20,488 SNPs. Branches are labeled with colors of the referral networks as indicated by the legend. Represented is the year of isolation, as well as the acquisition of fusB or fusC, fusA mutations, acquisition of dfrA, and dfrA mutations, and ermC acquisition as indicated by the legend.
