   Sammanfattning : Black grouse Tetrao tetrix is a bird species composed of large, continuous as well as severely reduced and fragmented populations, making it an optimal species to investigate how genetic diversity is affected by habitat fragmentation. I have focused on genetic diversity in the Major Histocompatibility Complex (MHC) to measure the ability of the black grouse to respond to environmental changes. LÄS MER

   Sammanfattning : Influenza A virus belongs to the Orothomyxoviridae family of viruses and is one of the most common pathogens that cause infections of the respiratory tract. The aim of this thesis was to investigate if neuraminidase inhibitor (NAI) Tamiflu® (oseltamivir, OC) and Relenza® (zanamivir, ZA) - related resistance mutations exist in the neuraminidase (NA) gene of viruses collected from wild birds.
