Abstract
Methods for growing and neutralizing or removing circoviruses, in particular porcine circoviruses, which are obtained from an infected cell culture after one or more passages in cultures of porcine, bovine or human cells are described. When the porcine circoviruses grow, a cytopathogenic effect occurs in the cell culture. The circoviruses can be neutralized by treatment with an antibody-containing substrate such as porcine serum or human immunoglobulin or be removed by a pasteurization method. Also described are a vaccine and a diagnostic aid containing inactivated or avirulent circoviruses.
