Tritrichomonads are small trichomonads (8-22 µm) with three anterior flagella and a recurrent flagellum forming a conspicuous undulating membrane with a posterior free portion. Costa stout or slender sustaining the undulating membrane; axostyle well developed; sausage-shaped parabasal. At the time of writing, there are about 20 species living in the intestinal tract of rodents, birds, reptiles and amphibians one species T. foetus is a parasite of the uro-genital tract of bovines. This image of Tritrichomonas foetus parasitic from uro-genital tract of the cattle (cows). It has three anterior flagella, a recurrent flagellum forming an undulating membrane with a free posterior part, a thick axostyle (immunofluorescence).

Tritrichomonas (try-try-koe-moan-ass), a trichomonas with three anterior flagella and one recurrent flagellum forming an undulating membrane seen on the lower faces of the cell. Also with an axostyle extending beyond the posterior end of the cell. Differential interference contrast.
