Genetic studies of health challenges and behaviour in the Havanese dog breed
(PhD Thesis;2023:30, Doctoral thesis, 2023)Havanese is the most registered companion dog breed in Norway, and is generally a healthy and long-lived breed. However, published studies, as well as health surveys conducted by the breed club, indicate a predisposition ... -
Genetic variation in Norwegian cervids : relevance to the occurrence of Chronic Wasting Disease (CWD)
(PhD Thesis;2021:51, Doctoral thesis, 2020)The etiological agents’ nature has a pivotal role in the pathogenesis of infectious diseases. Prion diseases are unique in having a misfolded protein (PrPSc) as the sole transmissible agent. The host cellular protein (PrPC) ... -
Genetics of chronic subclinical mastitis in Norwegian Red cows
(PhD Thesis;2020:19, Doctoral thesis, 2020)Chronic subclinical mastitis is an udder inflammation widely defined as milk somatic cell count (SCC) above 200 000 cells/ml for a prolonged period of time, often caused by bacterial infection. Several authors have studied ... -
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 ... -
Gut health and microbiota during the life cycle of Atlantic salmon (Salmo salar) produced under commercial Arctic conditions : modulation by functional feed ingredients investigated in vivo and in vitro
(PhD Thesis;2021:17, Doctoral thesis, 2021)The goal of this thesis was to fill some of the knowledge gaps regarding gut health and microbiota of Atlantic salmon in the life period from late freshwater to seawater in the Arctic region for which two strategies were ... -

(PhD Thesis;2015:28, Doctoral thesis, 2018-05-03)The Norwegian Goat Health Services (NGHS) initiated the Healthier goats disease eradication programme – Healthier Goats (HG) in 2002. The objectives of HG was to eradicate and control the three contagious diseases caseous ... -
Housing of laboratory mice in a natural habitat : influence on immune system, gut microbiota, and colorectal cancer development
(PhD thesis;2022:26, Doctoral thesis, 2022)The natural habitat for the house mouse is on the ground, typically close to humans and their livestock and hence surrounded by a rich microbial diversity that throughout evolutionary history has driven the adaptation of ... -
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 ... -
