abstract：:Infectious pancreatic necrosis is an important viral disease of salmonid fish reared in hatchery. Its etiological agent, IPNV, showed a high degree of antigenic heterogeneity. Up to 10 serotypes and 2 serogroups were proposed. Yet, very little is known about genomic variations among viruses of different origin. In ord...
