Figure 3: Dated phylogeny of BAPS groups 2 and 6 of S. suis.

The phylogenetic tree generated using the core genome of 45 isolates belonging to BAPS groups 2 and 6. BAPS grouping is overlaid over the branches where blue indicates BAPS group 2 and yellow BAPS group 6. Node labels indicate the posterior and the node bars indicate the 95% highest posterior density. The dates in years are shown on the x-axis. Major divergence events, coinciding with capsule switches, can be seen around 1875 and 1891.
