Porcine gut microbiota, short-chain fatty acids, and gut health in response to a high yeast inclusion diet
(PhD Thesis;2021:31, Doctoral thesis, 2021)The results of the PhD project have shown that high inclusion of Cyberlindnera jadinii yeast in pig feed exerts a prebiotic‑like effect. Beneficial intestinal lactic acid‑producing bacteria increase in numbers following ... -
Insect larvae meal as a feed ingredient for Atlantic salmon (Salmo salar) : effects on intestinal function, health, and microbiota
(PhD thesis;2021:75, Doctoral thesis, 2021)Being part of fish’s natural diets, insects have become a realistic, sustainable feed ingredient for aquaculture. While insects’ nutritional values have been extensively studied in numerous fish species, their impact on ... -
Immune responses in Atlantic salmon (Salmo salar) following vaccination and Salmonid alphavirus challenge
(Doctoral thesis, 2021)Norway has perfect conditions for Atlantic salmon (Salmo salar) production and is one of the largest producers of salmon for food consumption worldwide, but rearing fish at high densities also means that infectious disease ... -
Development of a total intravenous anaesthesia regime for use in pigs during live tissue training and biomedical research
(PhD Thesis;2021:55, Doctoral thesis, 2021)Large animal models are commonly used in biomedical research or for medical training purposes where cardiovascular instability is encountered. Pigs are frequently used as their cardiorespiratory anatomy and physiology are ... -
Persistent infection of Piscine orthoreovirus-1 (PRV-1) in Atlantic salmon (Salmo salar)
(PhD thesis;2021:49, Doctoral thesis, 2021)This thesis focuses on infection kinetics, infected cell types, viral shedding, and specific immune responses in persistently Piscine orthoreovirus-1 (PRV-1) infected Atlantic salmon. The aim is to enhance the understanding ... -

Plant-based aquafeeds : carry-over potential of mycotoxins and phytoestrogens from feed to fish and implication for fish health and food safety
(PhD Thesis;2020:62, Doctoral thesis, 2020)The introduction of novel feed ingredients has brought tremendous changes in the field of aquaculture. The shift to non-marine resources was necessary because of rising prices for fish meal and fish oil and their decreasing ... -
Persistent organic pollutants and effects on developmental and functional processes in mice
(PhD Thesis;2020:45, Doctoral thesis, 2020)Initial exposure to persistent organic pollutants (POPs) occurs by placental and lactational transfer during fetal and neonatal life and continues during the adult stage through ingestion, inhalation and dermal absorption. ... -
Detection of antibodies in Atlantic salmon using a bead-based multiplexed immunoassay
(PhD Thesis;2020:01, Doctoral thesis, 2020)Viral diseases are among of the main challenges in aquaculture in Norway today. Heart- and skeletal muscle inflammation, caused by Piscine orthoreovirus (PRV), and pancreas disease (PD), caused by Salmonid alphavirus (SAV), ... -
Quinolone resistant Escherichia coli in Norwegian livestock : a comparative genomics study
(PhD Thesis;2020:16, Doctoral thesis, 2020)The occurrence of antimicrobial resistance in Norwegian livestock is generally low. This is a consequence of good animal health and welfare, which reduces the need for antimicrobial use. Quinolones are important antimicrobial ... -
Piecing together the chain of infection for Streptococcus dysgalactiae in sheep and dairy cows - risk factors, sources, and genomic diversity of bacterial strains
(PhD Thesis;2022:63, Doctoral thesis, 2022)Streptococcus dysgalactiae subspecies dysgalactiae (SDSD) is an important cause of outbreaks of infectious arthritis in lambs and mastitis in dairy cows in Norway. The infections compromise animal welfare, increase ... -
Medaka (Oryzias latipes) gonadotropins : production and developmental profiles, pharmacological characterization of their receptors, and establishment of a novel transgenic line tg(fshb:DsRed2)
(PhD Thesis;2019:6, Doctoral thesis, 2019)The gonadotropins, follicle-stimulating hormone (Fsh) and luteinizing hormone (Lh), produced in gonadotrope cells of the pituitary, possess key roles in the endocrine control of vertebrate puberty and reproduction as part ... -
Exploring physiological functions of the prion protein in a new animal model
(PhD Thesis;2019:35, Doctoral thesis, 2019)The cellular prion protein (PrPC) has been intensively studied for its role in the pathogenesis of transmissible spongiform encephalopathies, such as Creutzfeldt-Jakob disease in human, bovine spongiform encephalopathy in ... -
Investigations on Cryptosporidium and Giardia in Tigray, Ethiopia from a One Health Perspective
(PhD Thesis;2022:54, Doctoral thesis, 2022)Enteric protozoans Cryptosporidium spp. and Giardia duodenalis are among the leading causes of diarrhoea in children. These parasites have particular impact in lowand middle-income countries. In these countries, people ... -
Gill infections, gill pathology and gill-related mortality in farmed Atlantic salmon
(PhD Thesis;2022:69, Doctoral thesis, 2022)Last year (2021) 54 million Atlantic salmon died at Norwegian food producing sea sites. This constitutes a loss of 15,5% of the fish that were transferred to sea. Gill diseases are among the health issues that causes ... -
