Pathogenicity of viral hemorrhagic septicemia virus IVb in walleye (Sander vitreus)Grice, Jessica 04 May 2012 (has links)
Recently, viral hemorrhagic septicemia virus (VHSV IVb) was associated with several walleye (Sander vitreus) mortality events in the Great Lakes. To examine the effects of route, strain-variation and temperature, walleye were experimentally infected with VHSV IVb using intraperitoneal (i.p.)-injection (102-108 pfu/fish) and immersion (w.; 1.4 x 107 virions mL-1). Walleye were relatively resistant to experimental infection with VHSV IVb, regardless of route or water temperature. High cumulative mortality (64-100%) and severe gross lesions associated with VHSV-IVb infection were only evident in fish i.p.-injected with 108 pfu at 12°C, which had mild to moderate, multifocal necrosis of several tissues including the gill and heart. There were significant differences in mortality between four walleye strains following i.p.-infection. Viral antigen was found in both i.p. and w.-exposed walleye using immunohistochemistry, mostly within the gill and skin epithelium of w.-exposed fish. VHSV IVb was detected in walleye tissues from 6-21 d post-infection using RT-qPCR. / Great Lakes Fisheries Commission and NSERC
