Characterization and mapping of monoclonal antibodies against the Sleeping disease virus, an aquatic alphavirus.
Sleeping disease virus (SDV) is an emerging pathogen in salmonid aquacultures, the impact of which is underestimated to date due to the lack of efficient diagnostic tools. To better characterize this new aquatic alphavirus and to make molecular tools available, a panel of monoclonal antibodies (mAbs) directed against SDV non-structural and structural proteins has been generated by immunizing mice with SDV-specific recombinant proteins overexpressed in Escherichia coli as antigens. So far, mAbs against nsP1, nsP3, E2 and E1 SDV proteins have been produced and their reactivity has been characterized by Western blot, radioimmunoprecipitation and indirect immunofluorescence assays. In addition, protein domains recognized by each mAb have been determined by immunofluorescence assay on truncated expressed SDV-derived proteins. Finally, one mAb directed against the E1 glycoprotein has been evaluated as a potential tool to be used in immunohistochemistry assay on experimentally infected trout.
