Some organisms in this order include:

Anatomy

Species in this order typically have four to six flagella at the cell's apical pole, one of which is recurrent - that is, it runs along a surface wave, giving the aspect of an undulating membrane. Like other parabasalids, they typically have an axostyle, a pelta, a costa, and parabasal bodies. In Histomonas only one flagellum and a reduced axostyle are found, and in Dientamoeba, both are absent.

Behavior

Most species are either parasites or other endosymbionts of animals.

Trichomonads reproduce by a special form of longitudinal fission, leading to large numbers of trophozoites in a relatively short time. Cysts never form, so transmission from one host to another is always based on direct contact between the sites they occupy.Kamaruddin, Mudyawati; Tokoro, Masaharu; Rahman, Md.

Treatment

The preferred treatment for trichomonad infection is Metronidazole.[1]

gollark: Meanwhile in C you have "error codes" and actually have to pass in output things by reference for stupid reasons and basically have Go-but-worse error handling.
gollark: It's waaaay nicer in Rust because they have the `?` operator.
gollark: Yes, lol no generics lol `if err != nil {return err}`
gollark: `a.out` is only 17KB!
