Trichomonas gallinae is a cosmopolitan parasite of birds including finches, pigeons, doves, turkeys, chickens, parrots, and raptors (hawks, golden eagle, etc.). The condition in birds of prey is called frounce.[1] It is believed to be an ancient pathogen causing frounce-like symptoms in theropod dinosaurs.[2] The same condition in pigeons is commonly called canker.
The protozoa are small (5 to 20 μm size) oval or spherical flagellates with four free flagella found on the anterior aspect of the parasite. They also have an axostyle found on the posterior end as well as an undulating membrane on one side.[3] An important diagnostic feature is the lack of a free posterior flagellum.
