Characterization of untranslated regions of the salmonid alphavirus 3 (SAV3) genome and construction of a SAV3 based replicon
Karlsen, Marius; Villoing, Stephane; Rimstad, Espen; Nylund, Are (Peer reviewed; Journal article, 2009-10-27)Salmonid alphavirus (SAV) causes disease in farmed salmonid fish and is divided into different genetic subtypes (SAV1-6). Here we report the cloning and characterization of the 5'- and 3'- untranslated regions (UTR) of a ... -
Characterization of ‘Candidatus Syngnamydia salmonis’ (Chlamydiales, Simkaniaceae), a bacterium associated with epitheliocystis in Atlantic salmon (Salmo salar L.)
Nylund, Stian; Steigen, Andreas; Karlsbakk, Egil; Plarre, Heidrun; Andersen, Linda; Karlsen, Marius; Watanabe, Kuninori; Nylund, Are (Peer reviewed; Journal article, 2015-01)Two Chlamydiales have previously been found to infect Atlantic salmon (Salmo salar L.), Candidatus Piscichlamydia salmonis and Candidatus Clavichlamydia salmonicola. Both develop intracellularly in cyst-like inclusions in ... -
Development of infectious cDNA clones of Salmonid alphavirus subtype 3
Karlsen, Marius; Villoing, Stephane; Ottem, Karl Fredrik; Rimstad, Espen; Nylund, Are (Peer reviewed; Journal article, 2010-09-21)Background: Salmonid alphavirus (SAV) is a widespread pathogen in European aquaculture of salmonid fish. Distinct viral subtypes have been suggested based on sequence comparisons and some of these have different geographical ... -
Wild and farmed salmon (Salmo salar) as reservoirs for infectious salmon anaemia virus, and the importance of horizontal- and vertical transmission
Nylund, Are; Brattespe, Jarle; Plarre, Heidrun; Kambestad, Martha Amalie; Karlsen, Marius (Peer reviewed; Journal article, 2019-04-16)The infectious salmon anaemia virus (ISAV) is an important pathogen on farmed salmon in Europe. The virus occurs as low- and high virulent variants where the former seem to be a continuous source of new high virulent ISAV. ...
