Comparison of polyclonal and monoclonal antibodies for serotyping infectious pancreatic necrosis virus (IPNV) strains isolated in eastern Canada.

This article focuses on the comparison of polyclonal and monoclonal antibodies for serotyping infectious pancreatic necrosis virus (IPNV) strains isolated in eastern Canada. IPNV, the aetiological agent of an important disease of salmonids, is a member of the Birnaviridae. Using polyclonal antibodies, three main serotypes have been distinguished according to their kinetics of neutralization in the presence of excess antibody by cross neutralization tests. All American strains are related to serotype I, while European isolates have been classified in serotypes II or III. Asian strains could belong to any of these three serotypes.
