Figure 4.

S. epidermidis taxon is made up of two groups. Maximum likelihood phylogenetic tree of S. epidermidis based on four-fold degenerate positions of genes in the core genome. The table shows the sequence type (ST) from multi-locus sequence typing. New sequence types and sequence types with a new allele are indicated by single and double asterisks, respectively. The RP62A and ATCC12228 strains are reference strains (NC_002976, NC_004461). Isolates SK135, BCM-HMP0060 and W23144 were sequenced as part of the Human Microbiome Project Reference Genome catalog. Nosocomial and commensal isolate names are colored red and green, respectively. Bootstrap values are shown on each branch. Outgroup (S. aureus) not shown.
