Virus replication in the digestive tract of ducks exposed by aerosol to type-A influenza.
Enteric infection and cloacal shedding of influenza virus was demonstrated in ducks exposed experimentally to an aerosol of an avirulent type-A influenza virus. The fluorescent-antibldy technique was used to identify sites of virus replication in the epithelial cells of the digestive tract and the bursa.
