title: [Studies on hepatitis vaccines in geese (author's transl)].
abstract: Three passages of goose hepatitis virus of muscoy duck embryo cell cultures were used as a vaccine in geese. The offspring of birds inoculated with the thirty-second of fifty-fifth passage were found to be immune to experimental infection with virulent goose hepatitis virus. The fifty-fifth passage, inoculated intramuscularly, did not result in transmission of the virus, neither through the hatching egg nor by direct contact. The eight-seventh passage was non-pathogenic for susceptible day-old goslings and produced active and adequate immunity in these young birds.
