Evolutionary relationships of the trichomonads. Phylogenetic tree of several members of the family Trichomonadidae based on 18S RNA sequences. The percentages of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) are shown next to the branches. The sequences of the ten positive specimens, shown by the red dots in the figure, were compared with 80 trichomonad sequences available in the National Center for Biotechnology Information database. The GenBank accession numbers are shown in parentheses. T. vaginalis, shown by a pink rhomboid in the figure, was used as a positive control and was grouped in the appropriate species clades
