Trichomoniasis (Trichomonas gallinae)

Overview

Trichomoniasis, caused by the parasite Trichomonas gallinae, is a common disease in birds, particularly affecting pigeons and doves. The disease can also affect other avian species, including raptors and poultry. It primarily causes lesions in the oral cavity, throat, and crop, leading to difficulty in eating and drinking.

Causes

Trichomoniasis is caused by the protozoan parasite Trichomonas gallinae. The infection is typically spread through contaminated water, food, or direct contact with an infected bird.
