Two-cluster population structure of T. vaginalis. Assignment of STs into two populations by STRUCTURE (A) and BAPS (B) was performed. The order of STs is the same in both graphs, and they are sorted by the percent ancestry into clade B (red) based on STRUCTURE analysis. The green cluster (n = 26 STs) and red cluster (n = 34 STs) are identical to the clades identified in the neighbor-joining tree. Asterisks indicate STs unassigned to populations (in panel A) and STs with significant admixture (in panel B).
