Fig. 4. Molecular dating of ST5 and ST8.

Fig. 4

a, b Bayesian maximum clade credibility time-calibrated phylogenies of a ST5 and b ST8 based on non-recombining regions of the core genome alignment. Branches colored in red represent genomes carrying SCCmec elements. The SCCmec types are represented by the colored dots at the tip of the branches. The divergence date (median estimate with 95% highest posterior density dates) is indicated as a horizontal blue line on the tree. For visual clarity, only the relevant divergence dates related to SCCmec acquisition are shown. Colored squares represent the presence of a mutation or genes associated with AMR and superantigens (SAg). c, d Condensed version of panels a and b showing the emergence of AMR classes as a function of the age of nodes when resistance mutations or genes were inferred to have emerged in c ST5 and d ST8.
