Figure 2.
A, Maximum likelihood tree of all sequenced samples. Heat map depicts clonal complexes (CCs), whether the samples are from a bloodstream infection (BSI), and accessory gene regulator (agr) group. B, CC8 cluster only. C, CC5 cluster only; branch tips indicate clusters <15 single-nucleotide polymorphisms. Clusters with only BSI strains are represented with circles; clusters with only skin and soft-tissue infection (SSTI) strains, with squares; and clusters including both BSI and SSTI strains, with triangles. Abbreviations: ID, identification; NA, not applicable; ST, sequence type. Branch lengths are proportional to the number of nucleotide substitutions per site (scale bars of 2x10−5 are provided for reference).
