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

    Author : Michelle Wille; Jonas Waldenström; Timm Harder; Linnéuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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;

    Abstract : 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. READ MORE

  2. 2. Epidemiology and population structure of Campylobacter jejuni and related organisms in wild birds

    Author : Jonas Waldenström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; epidemiology; Campylobacter lari; population structure; Helicobacter canadensis; Ecology; Parasitology human and animal ; Animal ecology; Djurekologi; Parasitologi människa och djur ; migration; Ekologi; wild birds; Sweden; Campylobacter jejuni;

    Abstract : Campylobacter jejuni is one of the most common causes to bacterial gastroenteritis in the industrialised world. Also other species of the Campylobacter genus give rise to human infections. C. jejuni occurs in many different animal hosts and can be isolated from water sources. READ MORE

  4. 4. Birds and Borrelia

    Author : Björn Olsen; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Borrelia; Ixodes ticks; Birds; Epidemiology; Zoonotisk ekologi; Zoonotic Ecology; Virology; Virologi; Mikrobiologi; Microbiology;

    Abstract : 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.

    Abstract : 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.
