Trichomonads
Trichomonads are flagellated protozoan parasites belonging to the phylum Parabasalia. They are characterized by their pear-shaped bodies, multiple flagella, and an undulating membrane that aids in their motility. Trichomonads typically inhabit the digestive tracts of animals, including humans, where they can cause infections such as trichomoniasis. These organisms reproduce by binary fission and are known for their ability to adapt to a wide range of environmental conditions.
