The effect of combined and separate infection by Alcaligenes faecalis and paramyxovirus (Yucaipa) on the surface morphology of the trachea in turkey poults.
Sixty-seven 1-day-old turkey poults were inoculated in the infra orbital sinus with 3 x 10(8) Alcaligenes faecalis bacteria and/or by 10(5.8)EID 50/ ml of Yucaipa virus. Twenty-five similar birds served as controls. Identification of the agents inoculated was made during the development of disease by means of isolation and serological tests. During the development of the disease, the surface morphology of the trachea in the affected animals revealed cellular oedema associated with a mucus coating of the cilia.
