  • Trichomonas vaginalis, an organism generally living inside the human urinogenital tract.
  • Trichomonas gallinae, which infects birds. Lesions found in the fossil jaws of tyrannosaurid dinosaurs such as Tyrannosaurus rex were likely caused by a parasite similar to Trichomonas gallinae.[1]

  • Trichomonas termopsidis, found in termite guts[2]
