Figure 2

Maximum likelihood phylogeny of MRSA CC398 isolates from Denmark (blue label) and from a worldwide collection (black label; Price et al., 2012). The maximum-likelihood phylogeny was inferred from a total of 3,954 single-nucleotide polymorphisms (SNPs), of which 1,098 were parsimony-informative. Color and shape of the branch endpoints indicate sample origin (see Legend). The three widespread Danish pig clones (clades P1–P3) are highlighted in green and the red-shaded area (clade H) highlights the isolates with the horse-specific marker SNP 309-2. The tree is midpoint rooted and numbers in broken branches indicate reduction factor in individual branch length.
