Serological response and virus shedding of chickens inoculated with reovirus via different routes.

A comparison of the serological responses to a reovirus administered by the eye-drop, intramuscular, oral and subcutaneous routes was made in three-week-old chickens. Their patterns of virus shedding were also compared. All four routes resulted in an antibody response and no virus excretion in faeces more than two to three weeks after administration. The oral route represented the most favourable route for live reovirus vaccine administration.
