Definition: A genus of parasitic protozoan flagellates (subfamily Trichomonidinae, family Trichomonadidae) causing trichomoniasis in humans, other primates, and birds. Specificity is more marked for its precise microhabitat than for host species. The genus has been divided into several genera: Trichomonas, Pentatrichomonas, Tetratrichomonas, and Tritrichomonas.
