Failure of orally administered attenuated goose parvovirus strain B to induce a humoral immune response in adult geese.
Two-month-old geese responded with the production of virus neutralising antibodies against virulent goose parvovirus strain B administered either per os or intramuscularly. They were shedding the virus within a short period after exposure. Humoral immune response in geese of the same age was induced by the attenuated goose parvovirus strain B only by intramuscular injection but not with per os administration.
