Bayesian phylogenetic tree of several members of the family Trichomonadinae based on ITS1-5.8S-rRNA-ITS2 sequences. The values at the nodes are posterior percentage probabilities obtained by using 106 generations. GenBank accession numbers are shown in parentheses. The arrows in the center of the tree indicate the new species, placed as an independent clade. T. tenax from the oral sample and T. vaginalis, used as the positive control, were grouped in their respective species clades.
