FIG 4.

Map of major transmission events. Countries where isolates were obtained from are shaded in light gray. Transmissions are indicated with arrows and colored according to the three major phylogenetic groups that were identified. Acquisition of agr and cap type is highlighted. The dating of transmission (95% HPD interval) as calculated by BEAST is given. Major lineages circulating to date are marked with blue, circular arrows, and the respective labels.
