==Introduction==
Trichomonas gallinae is the [[Protozoa | '''protozoal''']] pathogen responsible for [[Trichomonosis – Birds | '''Avian Trichomonosis''']].
The parasite is identifiable microscopically by its four '''anterior flagellae''' and well developed '''undulating membrane''' on one side.
''T. gallinae'' has no posterior flagellum.
Its body is divided by an ''axostyle''.
The '''ellipsoid nucleus''' of the parasite is usually found in the posterior aspect of the organism.
''T. gallinae'' requires sugars, starch and glycogen from host cells to survive and replicate.
==Transmission==
''Trichomonas gallinae'' is present '''worldwide''' in wild birds particularly the '''pigeon''' and other Columbids.
Transmission between pigeons occurs orally during feeding and mating behaviour.
Transmission to domestic chickens and turkeys is achieved through contaminated '''water troughs''' that have been visited by wild birds.
==Disease==
T gallinae causes '''yellow, necrotic lesions''' and plaques in the gastrointestinal tract of birds, particularly in the [[Crop]] and [[Oesophagus | oesophagus]].
'''[[Anaemia]]''' is caused when the parasite binds to [[Erythrocytes | erythrocytes]] and induces phagocytosis, causing '''haemolysis'''.
==Control==
Prevention of disease relies upon prevention of wild birds’ access to domestic birds and their water supplies.
