Abstract
Two independent non-overlapping epitopes could be demonstrated on the structural protein VP3 of infectious bursal disease virus by non-neutralizing monoclonal antibodies produced against serotypes I and II. Both serotypes have one epitope in common, whereas the second epitope is distinct for serotype I and serotype II.
