1. Viruses on the wing : evolution and dynamics of influenza A virus in the Mallard reservoir
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
2. Epidemiology and population structure of Campylobacter jejuni and related organisms in wild birds
Sammanfattning : 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. LÄS MER
3. Puumala virus dynamics in bank voles along habitat and community gradients : the ecology and risk of an emerging infectious disease
Sammanfattning : The majority of recent infectious disease outbreaks are zoonotic, i.e. caused by pathogens shared between humans and other vertebrates, and many of those originate in wildlife. The life cycle of zoonotic diseases is complex, and involves at least one non-human host. LÄS MER
4. Ticking off the ungulate box : the role of different ungulate species in the transmission of tick-borne pathogens
Sammanfattning : Ungulates play a central role in the life cycle of Ixodes ricinus, an important vector of tick-borne pathogens, and several ungulate species are increasingly common across Europe. I investigated the role of these different species in the spread of I. ricinus-borne pathogens. LÄS MER
5. The role of rodents in the transmission of Echinococcus multilocularis and other tapeworms in a low endemic area
Sammanfattning : Echinococcus multilocularis is zoonotic tapeworm in the Taeniidae family with a two part lifecycle involving a canid definitive host and a rodent intermediate host. The work of this thesis followed the first identification E. multilocularis in Sweden in 2011 in a red fox (Vulpes vulpes). LÄS MER
