Identification and characterization of two salmon louse heme peroxidases and their potential as vaccine antigens
Gislefoss, Elisabeth; Gamil, Amr Ahmed Abdelrahim; Øvergård, Aina-Cathrine; Evensen, Øystein (Journal article; Peer reviewed, 2023)Salmon louse, Lepeophtheirus salmonis, represents major challenge for salmon farming. Current treatments impose welfare issues and are costly, whereas prophylactic measures are unavailable. Two salmon louse heme peroxidases ... -
Mining Lepeophtheirus salmonis RNA-Seq data for qPCR reference genes and their application in Caligus elongatus
Borchel, Andreas; Eichner, Christiane; Øvergård, Aina-Cathrine (Journal article; Peer reviewed, 2023)Lepeophtheirus salmonis and Caligus elongatus are two parasitic copepod species posing a significant threat to salmonid aquaculture. Consequently, several gene expression studies are executed each year to gain new knowledge ... -
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 (Journal article; Peer reviewed, 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 E2 synthases in physiology and host–parasite interactions
Dalvin, Sussie; Eichner, Christiane; Dondrup, Michael; Øvergård, Aina-Cathrine (Journal article; Peer reviewed, 2021)Background 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 ... -
Salmon louse labial gland enzymes: implications for host settlement and immune modulation
Midtbø, Helena Marie Doherty; Eichner, Christiane; Hamre, Lars Are; Dondrup, Michael; Flesland, Linn; Tysseland, Kristoffer Helland; Kongshaug, Heidi; Borchel, Andreas; Nilsen, Frank; Øvergård, Aina-Cathrine (Journal article; Peer reviewed, 2024)Salmon louse (Lepeophtheirus salmonis) is a skin- and blood-feeding ectoparasite, infesting salmonids. While feeding, labial gland proteins from the salmon louse may be deposited on the Atlantic salmon (Salmo salar) skin. ... -
Small, charged proteins in salmon louse (Lepeophtheirus salmonis) secretions modulate Atlantic salmon (Salmo salar) immune responses and coagulation
Øvergård, Aina-Cathrine; Midtbø, Helena Marie Doherty; Hamre, Lars Are; Dondrup, Michael; Bjerga, Gro Elin Kjæreng; Larsen, Øivind; chettri, Jiwan Kumar; Buchmann, Kurt; Nilsen, Frank; Grotmol, Sindre (Journal article; Peer reviewed, 2022)Little is known about glandular proteins secreted from the skin- and blood-feeding ectoparasite salmon louse (Lepeophtheirus salmonis). The labial gland has ducts extending into the oral cavity of the lice, and the present ... -
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 (Journal article; Peer reviewed, 2023-05-01)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 (Journal article; Peer reviewed, 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 ...
