Fig 2. Maximum clade credibility (MCC) core genome phylogenetic tree with metadata annotated adjacent to the tips.

OspC types are displayed in color and annotated with text. The region of collection and RST type are labeled by colored boxes adjacent to the tips. Dissemination status is denoted with a star (disseminated isolates) or square (localized). WGS group is labeled by colored points on the outer rim of the. The posterior support for all nodes > 0.9 has been labeled in blue text. The tree scale is in nucleotide substitutions per site.
