Triple plaque purified strains of duck hepatitis virus and their potential as vaccines.
Individual triple plaque purified strains of attenuated duck hepatitis virus can protect ducklings against virulent challenge with the virus but they are as genetically unstable as their parent vaccine strains and are transmissible by direct contact. The use of rapid passage is advocated as a method to improve these parameters.
