Trichomonas gallinae is the [[Protozoa | '''protozoal''']] pathogen responsible for [[Trichomonosis - Birds | '''Avian Trichomonosis''']].  

''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.  

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''.

 

''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.

==Disease==

T gallinae causes '''yellow, necrotic lesions''' and plaques in the gastrointestinal tract of birds, particularly in the [[Crop - Anatomy and Physiology | crop]] and [[Oesophagus | oesophagus]].

''T. gallinae'' causes '''yellow, necrotic lesions''' and plaques in the gastrointestinal tract of birds, particularly in the [[Crop - Anatomy and Physiology | crop]] and [[Oesophagus | oesophagus]].

 

'''[[Anaemia]]''' is caused when the parasite binds to [[Erythrocytes | erythrocytes]] and induces phagocytosis, causing '''haemolysis'''. For more information see [[Trichomoniasis - Birds|avian trichomoniasis]].
