The protozoa resides on the surface and in the lumen of the female reproductive tract and in the crypt of penile epithelial cells. Transmission is achieved from infected individuals during mating and direct contact.

''T. foetus'' has no known cyst stage, although carrier cows occur very rarely and the pathogenesis of the carrier state is unknown. Therefore, trophozoites replicate simply by binary fission. It is thought that ''T. foetus'' feeds from host lipids and fatty acids <ref>Beach DH, Holz GGJr, Singh BN, Lindmark DG, 1991.

''T. foetus'' is sometimes isolated from foetal gut and lung but this is unlikely to be due to invasion and more likely due to swallowing or inhalation of amniotic fluid in utero.

''T. foetus'' mainly causes [[Diarrhoea|diarrhoea]] by colonisation of the large intestine. Recovery is slow but longterm prognosis is good. Reports of resistance and success are available for most anthelmintic and antibiotic therapies.

==Other ''Tritrichomonas'' spp.==

==Other trichomonad spp.==

Others such as ''Trichomonas suis'' and ''Trichomonas vaginalis'' reside as commensals, usually in the gastrointestinal tract of other species such as pigs and guinea pigs respectively. ''[[Trichomonas gallinae]]'' occurs in birds.

Many other trichomonads reside as commensals in the gastrointestinal tract of other species. Two of the most well studied trichomonads are ''[[Trichomonas gallinae]]'', which occurs in birds, and ''Trichomonas vaginalis'', which is a common sexually transmitted infection of humans.
