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 ... -
Complete genome of Atlantic halibut reovirus (AHRV) associated with mortality in production of Atlantic halibut (Hippoglossus hippoglossus) fry
Skoge, Renate Hvidsten; Nylund, Are; Solheim, Kjetil; Plarre, Heidrun (Peer reviewed; Journal article, 2019)The Aquareovirus (AQRV) member Atlantic halibut reovirus (AHRV) is associated with severe liver pathology and high fry mortality and constitutes a significant problem for Atlantic halibut (Hippoglossus hippoglossus) ... -
Genomic characterization and phylogenetic position of two new species in Rhabdoviridae infecting the parasitic copepod, salmon louse (Lepeophtheirus salmonis)
Økland, Arnfinn Lodden; Nylund, Are; Øvergård, Aina-Cathrine; Blindheim, Steffen H.; Watanabe, Kuninori; Grotmol, Sindre; Arnesen, Carl-Erik; Plarre, Heidrun (Peer reviewed; Journal article, 2014-11-17)Several new viruses have emerged during farming of salmonids in the North Atlantic causing large losses to the industry. Still the blood feeding copepod parasite, Lepeophtheirus salmonis, remains the major challenge for ... -
Infection dynamics and tissue tropism of Parvicapsula pseudobranchicola (Myxozoa: Myxosporea) in farmed Atlantic salmon (Salmo salar)
Nylund, Are; Hansen, Haakon; Brevik, Øyvind Jakobsen; Hustoft, Håvard; Markussen, Turhan; Plarre, Heidrun; Karlsbakk, Egil (Peer reviewed; Journal article, 2018-01-06)Background The myxosporean parasite Parvicapsula pseudobranchicola commonly infects farmed Atlantic salmon in northern Norway. Heavy infections are associated with pseudobranch lesions, runting and mortality in the salmon ... -
Infectious salmon anaemia virus (ISAV): Evolution, genotyping, reservoirs and transmission
Plarre, Heidrun (Doctoral thesis, 2012-06-01)The first officially registered outbreak of infectious salmon anaemia (ISA) started in Norway in November 1984 (Thorud and Djupvik, 1988). It was a chronically proceeding disease among Atlantic salmon (Salmo salar) parr ... -
A new aquareovirus causing high mortality in farmed Atlantic halibut fry in Norway
Blindheim, Steffen H.; Nylund, Are; Watanabe, Kuninori; Plarre, Heidrun; Erstad, Børre; Nylund, Stian (Peer reviewed; Journal article, 2015-01)A new aquareovirus was isolated from cultured Atlantic halibut (Hippoglossus hippoglossus) fry at a facility where massive mortalities had occurred during the start-feeding phase. The same virus was also detected in juveniles ... -
A new intracellular bacterium, Candidatus Similichlamydia labri sp. nov. (Chlamydiaceae) producing epitheliocysts in ballan wrasse, Labrus bergylta (Pisces, Labridae)
Steigen, Andreas L; Karlsbakk, Egil; Plarre, Heidrun; Watanabe, Kuninori; Øvergård, Aina-Cathrine; Brevik, Øyvind Jakobsen; Nylund, Are (Peer reviewed; Journal article, 2015-03)Certain wrasse species (Labridae) are used as cleaner fish in salmon farms on the Norwegian coast, reducing salmon louse intensities. The pathogen repertoire of wrasse in Norway is poorly known, and the objective of the ... -
Prevalence of infectious salmon anaemia virus (ISAV) in wild salmonids in western Norway
Plarre, Heidrun; Devold, M.; Snow, M.; Nylund, Are (Peer reviewed; Journal article, 2005-08-09)Studies of infectious salmon anaemia virus (ISAV), an important pathogen of farmed salmon in Norway, Scotland, the Faeroe Islands, Ireland, Canada, the USA and Chile, suggest that natural reservoirs for this virus can be ... -
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. ...
