Various grains and liquid as potential vehicles of transmission for Trichomonas gallinae.

Abstract

Although the main route of transmission of Tricliomnonas ga//mae is from infected adults to their young, it has been suggested (Stabler, 1954, Exptl. Parasitol. III: 368-402) that domestic poultry and uninfected adult columbids may become infected via water and feed contaminated by infected feral pigeons. The occurrence of tnichomonads in the upper digestive tract makes it possible for them to be expelled onto grain or into water during feeding or drinking.
