  1. 1. Viruses on the wing : evolution and dynamics of influenza A virus in the Mallard reservoir

    Författare :Michelle Wille; Jonas Waldenström; Timm Harder; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Co-infections; Ecology; Epidemiology; Evolution; Host-Parasite Interactions; Immunity; Influenza A Virus; Mallard; Phylogeny; Virology; Waterfowl; Wild Birds; Wildlife Disease; Zoonotisk ekologi; Zoonotic Ecology;

    Sammanfattning : This thesis explores the evolution of avian influenza A viruses (IAV), as well as host-pathogen interactions between these viruses and their main reservoir host, the Mallard (Anas platyrhynchos). IAV is a genetically diverse, multi-host virus and wild birds, particularly dabbling ducks, are the natural reservoir. LÄS MER

  5. 4. Birds and Borrelia

    Författare :Björn Olsen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Borrelia; Ixodes ticks; Birds; Epidemiology; Zoonotisk ekologi; Virology; Mikrobiologi;

    Sammanfattning : The Lyme disease causing spirochaete Borrelia burgdorferi sensu lato is transmitted by ticks within the genus Ixodes. These ticks are liberal host seekers and parasitise mammals, birds and reptiles.Prior to this study, the distribution of I. ricinus ticks and Lyme disease was thought to be restricted to the southern half of Sweden.

    Författare :Goran Orozovic; Björn Olsen; Johan Lennerstrand; Sigvard Olofsson; Linnéuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; influenza; mallards; neuraminidase; PCR; sequencing; mutation; oseltamivir; zanamivir; resistance; NAI; antivirals; pandemic; Virology; Virologi; Molecular biology; Molekylärbiologi; Bioinformatics; Bioinformatik; Zoonotisk ekologi; Zoonotic Ecology; Virology; Virologi; Biokemi; Biochemistry;

    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.
