==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.
