Introduction
Tritirchomonas foetus are protozoal pathogens causing disease primarily in cattle and felids. They are identifiable by theiir pear-like shape, three anterior flagellae (recurrent flagellum) and an undulating membrane on one side.
Lifecycle and Transmission
Cattle
Tritrichomonas foetus is a venereal disease in cattle causing early embryonic death and abortion.
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 th carrier state is unknown. Therefore, trophozoites replicate simply by binary fission. It is thought that T. foetus feeds from host lipids and fatty acids [1]
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.
Cats
Tritrichomonas foetus is transmitted via the faecal: oral route in cats. Behaviours such as grooming may aid transmission by direct contact. The venereal route is unproven in cats.
Other Tritrichomonas 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.
