Maximum likelihood single-nucleotide polymorphism (SNP) tree for 60 Staphylococcus aureus isolates, representing relationships between clonal complexes (CCs) in the Complicated Infection Group (CIG) and previously sequenced S aureus genomes. Single nucleotide polymorphisms were identified in pairwise genome comparisons between the predicted genes in all genomes. Single nucleotide polymorphisms for each genome were concatenated to form SNP pseudosequences and used to generate a phylogenetic tree using the HKY93 algorithm [28] with 500 bootstrap replicates.
