A new intracellular bacterium, Candidatus Similichlamydia labri sp. nov. (Chlamydiaceae) producing epitheliocysts in ballan wrasse, Labrus bergylta (Pisces, Labridae)
Steigen, Andreas; Karlsbakk, Egil; Plarre, Heidrun; Watanabe, Kuninori; Øvergård, Aina-Cathrine; Brevik, Øyvind; Nylund, Are (Journal article; Peer reviewed, 2014-11-22)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 ... -
Characterisation and expression analysis of the Atlantic halibut (Hippoglossus hippoglosssus L.) cytokines: IL-1β, IL-6, IL-11, IL-12β and IFNγ
Øvergård, Aina-Cathrine; Nepstad, Ina; Nerland, Audun H.; Patel, Sonal (Journal article; Peer reviewed, 2012)Genes encoding the five Atlantic halibut (Hippoglossus hippoglossus L.) cytokines; interleukin (IL)-1β, IL-6, IL-11b, IL-12βc, and interferon (IFN) γ, were cloned and characterised at a molecular level. The genomic ... -

Characterization of three salmon louse (Lepeophtheirus salmonis) genes with fibronectin II domains expressed by tegumental type 1 glands
Harasimczuk, Ewa; Øvergård, Aina-Cathrine; Grotmol, Sindre; Nilsen, Frank; Dalvin, Sussie (Peer reviewed; Journal article, 2017) -
Cloning, characterization, and expression pattern of Atlantic halibut (Hippoglossus hippoglossus L.) CD4-2, Lck, and ZAP-70
Øvergård, Aina-Cathrine; Nerland, Audun H.; Patel, Sonal (Journal article; Peer reviewed, 2010-12)As known from mammalia, the co-receptors CD4 or CD8 associate with a lymphocyte cell-specific kinase (Lck) upon T-cell activation. Lck phosphorylates tyrosine residues within the CD3 chains, providing docking sites for a ... -
Evaluation of potential reference genes for real time RT-PCR studies in Atlantic halibut (Hippoglossus Hippoglossus L.); during development, in tissues of healthy and NNV-injected fish, and in anterior kidney leucocytes
Øvergård, Aina-Cathrine; Nerland, Audun H.; Patel, Sonal (Journal article; Peer reviewed, 2010-05-11)Background Real time RT-PCR has become an important tool for analyzing gene expression in fish. Although several housekeeping genes have been evaluated in Atlantic halibut (Hippoglossus Hippoglossus L.), appropriate ... -
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 (Journal article; Peer reviewed, 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 ... -
Rainbow trout Oncorhynchus mykiss skin responses to salmon louse Lepeophtheirus salmonis: From copepodid to adult stage
Dalvin, Sussie; VG Jørgensen, Louise; Kania, Per W.; Grotmol, Sindre; Buchmann, Kurt; Øvergård, Aina-Cathrine (Peer reviewed; Journal article, 2020)The marine crustacean Lepeophtheirus salmonis (salmon louse) is a common ectoparasite of wild and farmed salmonids. The parasite has a complex ontogeny comprising eight instars. The planktonic copepodid stage settles on ... -
Roles of three putative salmon louse (Lepeophtheirus salmonis) prostaglandin E2synthases in physiology and host–parasite interactions
Dalvin, Sussie; Eichner, Christiane; Dondrup, Michael; Øvergård, Aina-Cathrine (Peer reviewed; Journal article, 2021)The salmon louse (Lepeophtheirus salmonis) is a parasite of salmonid fish. Atlantic salmon (Salmo salar) exhibit only a limited and ineffective immune response when infested with this parasite. Prostaglandins (PGs) have ... -
The thymus and T-cell ontogeny in ballan wrasse (Labrus bergylta) is nutritionally modelled
Etayo, Angela; Lie, Kai Kristoffer; Bjelland, Reidun Marie; Hordvik, Ivar; Øvergård, Aina-Cathrine; Sæle, Øystein (Peer reviewed; Journal article, 2023)Marine fish larvae often experience high mortality unrelated to predation during early life stages, and farmed ballan wrasse (Labrus bergylta) is no exception. Knowing when the adaptive immune system is developed and fully ... -
Transcriptomic and targeted immune transcript analyses confirm localized skin immune responses in Atlantic salmon towards the salmon louse
Øvergård, Aina-Cathrine; Eichner, Christiane; Nuñez-Ortiz, Noelia; Kongshaug, Heidi; Borchel, Andreas; Dalvin, Sussie Trine (Peer reviewed; Journal article, 2023)Atlantic salmon (Salmo salar) are highly susceptible to infestations with the ectoparasite Lepeophtheirus salmonis, the salmon louse. Infestations elicit an immune response in the fish, but the response does not lead to ...
