+==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.
