A Tribute to Nick Short
It is with extreme sadness that we share the news that one of WikiVet’s founders, Nick Short, has passed away.
Nick was the driving force behind WikiVet and all that it stood for, and it is thanks to his vision, innovative approach and tireless enthusiasm and belief, that WikiVet is available as a free resource to veterinary professionals around the world today. Nick’s dedication and passion for veterinary education were truly inspirational and his very many friends, colleagues and students across the world have lost a true gem. He was an exceptional human being: gentle, good-natured, charming, generous and kind: he has left many legacies which will ensure that he will be remembered for many years.
Our thoughts are with his friends and family at this heartbreaking time. A book of remembrance has been set up for anyone that would like to leave a message of condolence for Nick and his family have asked that anyone who wishes to do so make a donation to BipolarUK, a charity that was close to Nick’s heart.

|Species||T. foetus and more|
Also known as: Trichomonas foetus — Trichomonas fetus
Tritrichomonas foetus is a protozoal pathogen causing disease primarily in cattle and felids. It is identifiable by its pear-like shape, three anterior flagellae (recurrent flagellum) and an undulating membrane on one side.
Lifecycle and Transmission
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 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 
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.
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.
Proteinases secreted by T. foetus degrade substrates such as fibrinogen, albumin and immunoglobulins, thus altering the biological environment and resulting in embryonic death. Pyometra is occasionally observed in females but males show no clinical signs. For more information see Trichomonosis - Cattle.
T. foetus mainly causes 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 trichomonad spp.
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.
