The Atlantic Salmon Gill Transcriptome Response in a Natural Outbreak of Salmon Gill Pox Virus Infection Reveals New Biomarkers of Gill Pathology and Suppression of Mucosal Defense
Gjessing, Mona Cecilie; Krasnov, Aleksei; Timmerhaus, Gerrit; Brun, Svante; Afanasyev, Sergey; Dale, Ole Bendik; Dahle, Maria (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-04)The salmon gill poxvirus (SGPV) is a large DNA virus that infects gill epithelial cells in Atlantic salmon and is associated with acute high mortality disease outbreaks in aquaculture. The pathological effects of SGPV infection include gill epithelial apoptosis in the acute phase of the disease and hyperplasia of gill epithelial cells in surviving fish, causing damage to the gill respiratory surface. ... -

Development of Atlantic Salmon (Salmo salar L.) Under Hypoxic Conditions Induced Sustained Changes in Expression of Immune Genes and Reduced Resistance to Moritella viscosa
Krasnov, Aleksei; Burgerhout, Erik; Johnsen, Hanne; Tveiten, Helge; Bakke, Anne Flore; Lund, Hege; Afanasyev, Sergey; Rebl, Alexander; Johansen, Lill-Heidi (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-02)Atlantic salmon is characterized with high sensitivity to low dissolved oxygen (DO) levels. Hypoxia can affect diverse biological processes with consequences that can be manifested immediately or with delay. Effects of hypoxia on the immune system and the resistance to a bacterial pathogen were investigated. Two groups were reared at, respectively, normal (NO, 80–100%) and low (LO, 60%) levels of ... -
Morphology, Transcriptomics and In Vitro Model of Skin from Polar Cod (Boreogadus Saida) and Atlantic Cod (Gadus Morhua)
Ytteborg, Elisabeth; Hansen, Øyvind Johannes; Høst, Vibeke; Afanasyev, Sergey; Vieweg, Ireen; Nahrgang, Jasmine; Krasnov, Aleksei (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-04)Fish skin is a multifunctional barrier tissue with high regeneration capacity that interacts with the surrounding environment and provides protection. Functional importance, high complexity and activity make skin an attractive tissue for studying the effects of environmental challenges and chemical stressors in fish. The aim of this work was to characterize skin from polar cod (<i>Boreogadus saida</i>) ...
