Identification and Description of the Key Molecular Components of the Egg Strings of the Salmon Louse (Lepeophtheirus salmonis)
(Peer reviewed; Journal article, 2019-12-03)The salmon louse Lepeophtheirus salmonis is a parasite of Atlantic salmon and other salmonids. Every year, it causes high costs for the Norwegian aquaculture industry. While the morphology of the female genital tract has ... -
Identification and genetic characterization of Saprolegnia parasitica, isolated from farmed and wild fish in Finland
(Journal article; Peer reviewed, 2023)Oomycete infections in farmed fish are one of the most significant disease issues in salmonid aquaculture worldwide. In the present study, Saprolegnia spp. in different farmed fish species in Finland were identified, and ... -
Identification and molecular characterization of two acetylcholinesterases from the salmon louse, Lepeophtheirus salmonis
(Peer reviewed; Journal article, 2015-05-04)Acetylcholinesterase (AChE) is an important enzyme in cholinergic synapses. Most arthropods have two genes (ace1 and ace2), but only one encodes the predominant synaptic AChE, the main target for organophosphates. Resistance ... -
Identification of critical enzymes in the salmon louse chitin synthesis pathway as revealed by RNA interference-mediated abrogation of infectivity
(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 ... -
Identification of Epigenetic Modifications Following Treatment with Olanzapine
(Master thesis, 2018-12-19)No chronic disease burdens the world more than psychiatric disorders (Collins et al., 2011), with an estimated 40% of the population in 30 European countries affected in any given year (Insel et al., 2012). Current medical ... -
Identification of housekeeping genes of Candidatus Branchiomonas cysticola associated with epitheliocystis in Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2022)Candidatus Branchiomonas cysticola is an intracellular, gram-negative Betaproteobacteria causing epitheliocystis in Atlantic Salmon (Salmo salar L.). The bacterium has not been genetically characterized at the intraspecific ... -
Identification of immunogenic surface proteins of Pasteurella atlantica genomovar salmonicida
(Master thesis, 2023-06-02) -
Identification of in vivo induced antigens of the malacosporean parasite Tetracapsuloides bryosalmonae (Cnidaria) using in vivo induced antigen technology
(Journal article; Peer reviewed, 2022)Tetracapsuloides bryosalmonae is a malacosporean endoparasite that causes proliferative kidney disease (PKD) in wild and farmed salmonids in Europe and North America. The life cycle of T. bryosalmonae completes between ... -
Identification of key components in the energy metabolism of Archaeoglobus fulgidus by transcriptome analyses
(Peer reviewed; Journal article, 2014-03-11)Energy conservation via the pathway of dissimilatory sulfate reduction is present in a diverse group of prokaryotes, but is most comprehensively studied in Deltaproteobacteria. In this study, whole-genome microarray analyses ... -
Identification, production and characterization of novel marine enzymes.
(Master thesis, 2024-06-03)Global drivers are causing a shift in the discovery of novelty, for a more sustainable, greener future. Chemical catalysts have been widely used in various industries. However, microbial enzymes of high tolerance to harsh ... -
Identifying the driving factors behind observed elevational range shifts on European mountains
(Peer reviewed; Journal article, 2014-04-13)Aim In recent decades species ranges have shifted upwards in elevation and northwards in latitude. These shifts are commonly interpreted as a response to recent climate warming. However, several alternative hypotheses have ... -
IgE sensitization to the fish parasite Anisakis simplex in Norway
(Doctoral thesis, 2015-05-11)Anisakis simplex is a fish parasite which infects many commercially important fish species worldwide. When ingested in contaminated raw or poorly prepared seafood, this parasite may lead to infection and/or allergic reaction ... -
Immunoglobulin Isotypes in Atlantic Salmon, Salmo Salar
(Peer reviewed; Journal article, 2015-02)There are three major immunoglobulin (Ig) isotypes in salmonid fish: IgM, IgD and IgT, defined by the heavy chains , and , respectively. As a result of whole genome duplication in the ancestor of the salmonid fish family, ... -
Immunrespons mot Pasteurella spp. hjå rognkjeks (Cyclopterus lumpus L.) og Atlantisk laks (Salmo salar L.)
