(PhD Thesis;2017:98, Doctoral thesis, 2017)The livestock sector in Tanzania is huge in animal numbers but the production is disproportionally small. Most of the infections known to cause reproductive disorders are generally regarded endemic in Africa, but more ... -
The cellular prion protein and the inflammatory response
(PhD Thesis;2017:81, Doctoral thesis, 2017)The cellular prion protein (PrPC) is known for its pivotal role in the development of prion diseases, such as Creutzfeldt-Jakob disease in humans and scrapie in small ruminants. In these diseases, PrPC is converted into a ... -
Effects of the rearing period and the production phase on fear-related responses in adult laying hens
(PhD Thesis;2017:48, Doctoral thesis, 2017)In 2013, almost seven billion laying hens (Gallus gallus domesticus) produced eggs for human consumption (CIWF, 2013). Under commercial egg production, specialised rearing farmers keep the birds until they are nearly ... -
Studies on the interbranchial lymphoid tissue in the gills of Atlantic salmon and common carp
(PhD Thesis;2017:17, Doctoral thesis, 2017)As wild-capture fisheries exceed sustainable levels, aquaculture is expected to increase its importance as a source of fish products for a growing world population. Vaccination is a major prophylactic measure in modern ... -
Characterization of salmonid alphavirus subtype 3 : recombination and adaptation
(PhD Thesis;2016:59, Doctoral thesis, 2017-07-04)Pancreas disease (PD) affecting Atlantic salmon (Salmo salar L.) and rainbow trout (Oncorhynchus mykiss) is a major burden in European salmonid aquaculture and causes major economical losses every year. The disease is ... -
Salmonid alphavirus infection in Atlantic salmon : viral properties and host responses to infection
(PhD Thesis;2015:2, Doctoral thesis, 2017-07-04)Pancreas disease (PD) is a contagious viral disease in salmonid aquaculture in Europe and North America. PD is caused by salmon pancreas disease virus also referred to as salmonid alphavirus (SAV), which belongs to the ... -
Investigation of the gut-associated lymphoid tissue in sheep with emphasis on natural killer cells
(PhD Thesis;2015:52, Doctoral thesis, 2017-07-04)The gut-associated lymphoid tissue (GALT) of sheep has been investigated for decades, and several immune cells receding within these structures have been described. The GALT of sheep has specialized compartments described ... -
Symmetrical onychomadesis and hypothyroidism in the Gordon Setter and English Setter
(PhD Thesis;2015:58, Doctoral thesis, 2017-07-04)Symmetrical onychomadesis (SO), also called symmetrical lupoid onychodystrophy, is a severe claw disease frequently seen in the Gordon Setter (GS) and English Setter (ES). Affected dogs will initially show sudden onset of ... -
Genetic studies of canine anxiety
(PhD Thesis;2016:51, Doctoral thesis, 2017-07-04)Canine anxiety is a common behavioral problem in dogs, affecting the dog’s welfare and health, and causing a strain in the relationship between the dog and its owner. Undesirable behaviors, including anxiety disorders, ... -
Studies of mechanisms of virulence of viral hemorrhagic septicemia (VHS) : comparison between different genotypes of the virus
(PhD Thesis;2015:17, Doctoral thesis, 2017-07-04)Viral hemorrhagic septicemia virus (VHSV) has four major genotypes (I, II, III, and IV) with different sub-lineages (Ia-e and IVa-c). VHSV infects a wide-host-range with a preference for low-temperature environments. The ... -
