Deoxynivalenol in pigs : effects, toxicokinetics, vertical transmission and microbial detoxification
(PhD Thesis;2018:99, Doctoral thesis, 2019)Mycotoxins are secondary metabolites of fungi that can have a variety of adverse effects on animals and humans. One of the most common mycotoxins produced by Fusarium fungi is the trichothecene deoxynivalenol (DON), and ... -
Detection and quantification of the food-related bacterial toxins cereulide, lichenysin and botulinum neurotoxin/CD with liquid chromatography – tandem mass spectrometry
(PhD Thesis;2015:103, Doctoral thesis, 2017-07-13)Food‐ and waterborne illness has a tremendous impact on the society, both economically and through the vast number of diseased people. Increased focus on food safety both at the consumer level and in the food producing ... -
Detection and viability assessment of foodborne parasites of public health importance on berries
(PhD Thesis;2021:11, Doctoral thesis, 2021)Foodborne parasites (FBP) are public health concern throughout the world causing significant effects on the health and wellbeing of people. Despite the tremendous impact of FBP, the relative attention paid to avert their ... -
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), ... -
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 ... -
Development, optimization and field testing of a filtration method for detection of salmonid alphavirus in seawater
(PhD thesis;2021:38, Doctoral thesis, 2021)The commercial aquaculture is continuously growing with the demand for fish and seafood products. In Norway, Atlantic salmon (Salmo salar L.) constitute 94 % of the total aquaculture production, making it the most important ... -
Early environmental effects on laying hen development
(PhD Thesis;2016:57, Doctoral thesis, 2018-05-04)Chickens are widely used by humans in both farm production and in scientific research as model organisms. In the farming industry, they total 27 billion individuals worldwide (FAO, 2013). Over 6 billion of these are laying ... -
The effect of food chain stressors on Listeria monocytogenes
(PhD Thesis;2021:12, Doctoral thesis, 2021)Listeria monocytogenes is the causative agent of food-borne listeriosis, a disease often transmitted by contaminated Ready-To-Eat (RTE) food. Immunosuppressed individuals, fetuses, and the elderly are at higher risk of ... -
Effects of a controlled immune activation on social behaviour, neurophysiology and the acute phase response in pigs
(PhD Thesis;2021:69, Doctoral thesis, 2021)Damaging behaviours, such as tail and ear biting, are important animal welfare challenges in commercial pig production. Poor health is a risk factor for damaging behaviours but the mechanisms behind this link remain unknown. ... -
Effects of environmental complexity during rearing and laying on fearfulness, spatial cognition and neural plasticity in laying hens
(PhD Thesis;2023:56, Doctoral thesis, 2023)Due to an increased demand from citizens, the egg industry in the European Union is moving towards more welfare friendly housing systems. However, these environments are often more complex, and hens are still exposed to ... -
Effects of gonadotropin-releasing hormone agonist on brain development and aging : results from two animal models
(PhD Thesis;2014:32, Doctoral thesis, 2014)Normal brain maturation is the result of many structural and molecular changes that can be modulated by endocrine variables and is associated with brain plasticity and sex- and age specific differences in cognitive ... -
Effects of meat and meat components on intestinal carcinogenesis in the A/J Min/+ mouse model
(PhD Thesis;2017:06, Doctoral thesis, 2017)Colorectal cancer (CRC) represents a major public health burden worldwide, and particularly in the developed countries. Sporadic CRC has been associated with a number of lifestyle factors, including smoking, alcohol ... -
Effects of persistent organic pollutants (POPs) on the steroidogenesis of primary neonatal porcine Leydig cells
(PhD thesis;2019:7, Doctoral thesis, 2019)After World War II the production of manmade chemicals has increased immensely. They are made to give desired practical properties and functions. Some are added to consumer products to provide conductivity, increase flame ... -

(PhD thesis;2020:40, Doctoral thesis, 2020)Zebrafish (Danio rerio) are increasingly popular model animals in scientific fields ranging from behavioural ecology to neurobiology. It is therefore of increasing concern that half of all zebrafish research facilities are ... -
Effects of the hatchery environment on neurobiology and behaviour in Atlantic salmon : implications for stocking
(PhD Thesis;2018:80, Doctoral thesis, 2018)The Atlantic salmon (Salmo salar) is an iconic fish species with a widespread historic abundance, but recent decades have witnessed a dramatic decline in wild stocks due to a variety of anthropogenic factors, especially ... -
Effects of the rearing period and the production phase on fear-related responses in adult laying hens
