Characterization of a VHS virus genotype III isolated from rainbow trout (Oncorhychus mykiss) at a marine site on the west coast of Norway
Duesund, Henrik; Nylund, Stian; Watanabe, Kuninori; Ottem, Karl Fredrik; Nylund, Are (Peer reviewed; Journal article, 2010-01-26)Background Norwegian production of rainbow trout (Oncorhynchus mykiss) has been without any outbreaks of VHS for many years until the disease emerged in a farm in western Norway in November 2007. The fish were, in addition ... -
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 ... -
Concurrent jellyfish blooms and tenacibaculosis outbreaks in Northern Norwegian Atlantic salmon (Salmo salar) farms
Småge, Sverre Bang; Brevik, Øyvind Jakobsen; Frisch, Kathleen Marie; Watanabe, Kuninori; Duesund, Henrik; Nylund, Are (Peer reviewed; Journal article, 2017-11-02)Tenacibaculosis is an increasing problem in the Norwegian Atlantic salmon aquaculture industry causing significant economic losses. In September 2015, two separate outbreaks of suspected tenacibaculosis occurred at two ... -
First isolation, identification and characterisation of Tenacibaculum maritimum in Norway, isolated from diseased farmed sea lice cleaner fish Cyclopterus lumpus L
Småge, Sverre Bang; Frisch, Kathleen; Brevik, Øyvind Jakobsen; Watanabe, Kuninori; Nylund, Are (Peer reviewed; Journal article, 2016-06-23)The use of cleaner fish as biological controls of salmon lice (Lepeophtheirus salmonis) has increased exponentially in the last decade in Norwegian Atlantic salmon (Salmo salar) production. This alternative to chemical ... -
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 ... -
Induction of tenacibaculosis in Atlantic salmon smolts using Tenacibaculum finnmarkense and the evaluation of a whole cell inactivated vaccine
Småge, Sverre Bang; Frisch, Kathleen Marie; Vold, Vidar; Duesund, Henrik; Brevik, Øyvind Jakobsen; Olsen, Rolf Hetlelid; Sjaatil, Stine; Klevan, Are; Brudeseth, Bjørn; Watanabe, Kuninori; Nylund, Are (Peer reviewed; Journal article, 2018-10)Tenacibaculosis, an ulcerative disease characterised by skin lesions, mouth erosion, frayed fins and tail rot, is a significant fish welfare issue in marine aquaculture worldwide. The disease is a concern to the Atlantic ... -
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 ... -
