1. Development and maintenance of quality indicators in pheasants
Sammanfattning : Females often base their choice of mates on the expression, size or intensity, of male sexual ornaments. Indicator models of sexual selection assume that females assess male genetic quality through the expression of these secondary sexual characters. LÄS MER
2. Adverse Reactions after Vaccination and Allergen-Specific Immunotherapy: Contact Allergy to Aluminium and Itching Nodules
Sammanfattning : The aim of the work presented in this thesis was to investigate two different types of adverse reactions, persistent itching nodules and contact allergy to aluminium, after immunization with aluminium-containing vaccines and aluminium-containing allergen extracts used for allergen-specific immunotherapy (ASIT). The first paper describes active parental reporting of adverse events (AEFIs) after a booster dose of diphtheria-tetanus vaccine (DT). LÄS MER
3. Arcanobacterium haemolyticum, clinical, diagnostic and therapeutic aspects
Sammanfattning : In an 18-month period all throat cultures in our laboratory were examined for Arcanobacterium haemolyticum and clinical information was obtained. The great majority of the patients suffered from pharyngitis or tonsillitis, accompanied by a rash in 46% of cases. One third of the patients had a history of recurrent tonsillitis. LÄS MER
4. Costs in the ecology and evolution of the vertebrate immune system
Sammanfattning : A central assumption of theories of the ecology and evolution of immunological defence is that defence has not only benefits (in the form of resistance against parasites), but also costs. The aim of my studies was to investigate the nature and magnitude of costs of the vertebrate immune system, and to examine some of the consequences of these costs. LÄS MER
5. Causes and consequences of blood parasite infections in birds
Sammanfattning : Parasites are ubiquitous and can cause significant fitness reductions to their hosts. Therefore, selection for the evolution of host resistance should be strong. However, resistance may be costly and should be traded-off against other fitness related traits. LÄS MER
