What causes trichomoniasis in birds
Trichomoniasis is an infectious disease of birds caused by the single-celled protozoan Trichomonas gallinae. There are several different strains of this protozoan, some of which cause clinical disease, while some of which do not. This disease is also known as canker in pigeons and doves, and frounce in raptors.
