Generation and characterization of a PRRSV-2 DIVA marker virus by deletion of a novel epitope in the nucleocapsid protein
The feasibility of developing a PRRSV DIVA vaccine through targeted modification of an N protein epitope is demonstrated, providing a potential strategy to facilitate PRRS control and suggests that combining the recombinant virus with cELISA diagnostic tests allows accurate differentiation between vaccinated and wild-t...
