Effects of the brain-infecting parasite Pseudoloma neurophilia in laboratory zebrafish (Danio rerio)
(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 ... -
Clinical and clinicopathological characteristics in canine Vipera berus envenomation
(PhD Thesis;2021:71, Doctoral thesis, 2021)Envenomation of dogs by the European adder (Vipera berus (V. berus)) is a common emergency in veterinary practice in Europe. Despite its common nature, little research exists regarding the clinical effects of this type of ... -
Choline is an essential nutrient for post-smolt Atlantic salmon (Salmo salar L)
(PhD Thesis;2020:27, Doctoral thesis, 2020)The aquaculture feed industry continuously works to decrease the share of marine ingredients in the diets by searching for alternative feed ingredients. The increased use of such ingredients, on one hand expose the fish ... -
Neurodevelopmental toxicity of a human relevant mixture of persistent organic pollutants (POPs) and perfluorooctane sulfonic acid (PFOS)
(PhD Thesis;2021:63, Doctoral thesis, 2021)Persistent organic pollutants (POPs) are ubiquitous in the environment. Humans are continuously exposed to chemical mixtures through food and the environment. Exposure to POPs have been associated with several adverse ... -
Pathogenesis studies of cardiomyopathy syndrome (CMS) in Atlantic salmon, Salmo salar L.
(PhD Thesis;2021:78, Doctoral thesis, 2021)Cardiomyopathy syndrome (CMS) in farmed Atlantic salmon, Salmo salar L., is an infectious viral disease causing severe inflammation in the cardiac spongiosum of atrium and ventricle of the salmonid heart. The disease was ... -
Melanised focal changes in Atlantic salmon : interactions between infection and immunity
(PhD Thesis;2021:82, Doctoral thesis, 2022)Atlantic salmon (Salmo salar) farming has increased rapidly in Norway over the last 50 years. However, the large-scale farming of salmon battles serious health problems. There are currently many adverse conditions threatening ... -
Prevalence of anticoagulant rodenticides in dogs and red foxes
(PhD Thesis;2020:61, Doctoral thesis, 2021)Anticoagulant rodenticides (AR) are used worldwide in urban and agricultural rodent pest control. Ingestion of ARs is a major cause of poisoning in dogs and secondary exposure (ingestion of poisoned prey) in wildlife is a ... -
Epidemiology of orthopaedic conditions in companion animals with emphasis on cranial cruciate ligament disease
(PhD Thesis;2019:78, Doctoral thesis, 2019)Lameness caused by orthopaedic disease is an important reason for owners to take their dog or cat to the veterinarian. Many diagnoses, such as cranial cruciate ligament disease (CCLD), considered the most common cause 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. ... -
Tilapia Lake Virus (TiLV) : development of PCR-based diagnostic assays and insights into infection mechanisms
(PhD Thesis;Thesis 2021:30, Doctoral thesis, 2021)Tilapia lake virus (TiLV) is an emerging virus of wild and farmed tilapiines responsible for causing mortalities and significant economic losses to the aquaculture industry. Since its first report in Israel, the virus has ... -
Impact of feed composition on rearing of broiler chickens without in-feed antimicrobials
(PhD Thesis;2021:41, Doctoral thesis, 2021)In-feed antimicrobials with antibiotic properties have been used for disease-preventive and performance-promoting purposes in rearing of broiler chickens since the mid-twentieth century. The use of antibiotic agents in ... -
Cocktails of persistent organic pollutants lead to behavioural and reproductive toxicity
(PhD thesis;2017:30, Doctoral thesis, 2017)Persistent organic pollutants (POPs) are chemicals that widely distributed in the environment and biota that could cause neurobehavioural and reproductive toxicity. As humans and animals are exposed to a complex mixture ... -
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 ... -
Bacterial impact on growth, health and disease of farmed Atlantic salmon and lumpfish
