Caligus rogercresseyi acetylcholinesterase types and variants: a potential marker for organophosphate resistance
Agusti-Ridaura, Celia; Dondrup, Michael; Horsberg, Tor Einar; Leong, Jong S; Koop, Ben F; Bravo, Sandra; Mendoza, Julio; Kaur, Kiranpreet (Peer reviewed; Journal article, 2018-10-30)Background Control of the sea louse Caligus rogercresseyi in the Chilean salmonid industry is reliant on chemical treatments. Azamethiphos was introduced in 2013, although other organophosphates were previously used. In ... -
Finding a Needle in the Virus Metagenome Haystack - Micro-Metagenome Analysis Captures a Snapshot of the Diversity of a Bacteriophage Armoire
Ray, Jessica; Dondrup, Michael; Modha, Sejal; Steen, Ida Helene; Sandaa, Ruth-Anne; Clokie, Martha (Peer reviewed; Journal article, 2012-04-11)Viruses are ubiquitous in the oceans and critical components of marine microbial communities, regulating nutrient transfer to higher trophic levels or to the dissolved organic pool through lysis of host cells. Hydrothermal ... -
Host gill attachment causes blood-feeding by the salmon louse (Lepeophtheirus salmonis) chalimus larvae and alters parasite development and transcriptome
Heggland, Erna Irene; Dondrup, Michael; Nilsen, Frank; Eichner, Christiane (Journal article; Peer reviewed, 2020-05-06)Background: Blood-feeding is a common strategy among parasitizing arthropods, including the ectoparasitic salmon louse (Lepeophtheirus salmonis), feeding off its salmon host’s skin and blood. Blood is rich in nutrients, ... -
Identification of critical enzymes in the salmon louse chitin synthesis pathway as revealed by RNA interference-mediated abrogation of infectivity
Braden, Laura; Michaud, Dylan; Igboeli, Okechukwu O.; Dondrup, Michael; Hamre, Lars Are; Dalvin, Sussie; Purcell, Sara; Kongshaug, Heidi; Eichner, Christiane; Nilsen, Frank; Fast, Mark D. (Journal article; Peer reviewed, 2020)Treatment of infestation by the ectoparasite Lepeophtheirus salmonis relies on a small number of chemotherapeutant treatments that currently meet with limited success. Drugs targeting chitin synthesis have been largely ... -
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 ... -
The salmon louse genome: Copepod features and parasitic adaptations
Skern-Mauritzen, Rasmus; Malde, Ketil; Eichner, Christiane; Dondrup, Michael; Furmanek, Tomasz; Besnier, Francois; Komisarczuk, Anna Zofia; Nuhn, Michael; Dalvin, Sussie; Edvardsen, Rolf Brudvik; Klages, Sven; Huettel, Bruno; Stueber, Kurt; Grotmol, Sindre; Karlsbakk, Egil Erlingsson; Kersey, Paul; Leong, Jong S; Glover, Kevin Alan; Reinhardt, Richard; Lien, Sigbjørn; Jonassen, Inge; Koop, Ben F; Nilsen, Frank (Journal article; Peer reviewed, 2021)Copepods encompass numerous ecological roles including parasites, detrivores and phytoplankton grazers. Nonetheless, copepod genome assemblies remain scarce. Lepeophtheirus salmonis is an economically and ecologically ... -
A scavenger receptor B (CD36)-like protein is a potential mediator of intestinal heme absorption in the hematophagous ectoparasite Lepeophtheirus salmonis
Eichner, Christiane; Støve, Svein Isungset; Martinez, Aurora; Nilsen, Frank; Dondrup, Michael (Peer reviewed; Journal article, 2019-03-12)Intestinal absorption of heme has remained enigmatic for years, even though heme provides the most bioavailable form of iron. The salmon louse, Lepeophtheirus salmonis, is a heme auxotrophic ectoparasite feeding on large ...
