Infection and Death in the Pigeon Resulting from the Oral Implantation of Single Individuals of Trichomonas gallinae

Abstract

Single specimens of a highly virulent strain of T. gallinae produced fatal infections in Trichomonas -free pigeons. Five birds so infected died in an average of 11.8 days. Five which did not become positive after receiving orally 1 T. gallinae each, died in an average of 7.6 days following oral administration of 5000-10,000 virulent T. gallinae per bird.
