FIG. 4.

Bayesian likelihood inference phylogeny based on wsp sequences of the 36 strains analyzed by MLST (without the T. deion strain). ST complexes and strains with identical STs identified by MLST are highlighted. Arrows and asterisks indicate two examples of strain pairs whose predicted relationships are highly discordant with the MLST phylogeny (Fig. 4). The supergroup placement of the A. sparsa and S. invicta strains based on MLST phylogeny (in parentheses) (Fig. 3) is not supported by the wsp-based phylogeny. Posterior probability (left) and parsimony bootstrap (right) values are shown at major nodes if they were supported by both clustering algorithms.
