  1. 1. The Origin of the Genus Flavivirus and the Ecology of Tick-Borne Pathogens

    Författare :John H.-O. Pettersson; Thomas Jaenson; Sven Bergström; Kenneth Nilsson; Mikael Thollesson; Per-Eric Lindgren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Flavivirus; Virus dating; Molecular dating; Biogeography; Ixodes ricinus; Minimum infection rate; TBE; Tick-borne encephalitis virus; Rickettsia helvetica; Anaplasma phagocytophilum; Infection prevalence; RT-PCR; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Sammanfattning : The present thesis examines questions related to the temporal origin of the Flavivirus genus and the ecology of tick-borne pathogens. In the first study, we date the origin and divergence time of the Flavivirus genus. It has been argued that the first flaviviruses originated after the last glacial maximum. LÄS MER

  3. 2. Dispersal of ticks and their microorganisms by African-Western Palaearctic migratory birds

    Författare :Tove Hoffman; Björn Olsen; Åke Lundkvist; Kenneth Nilsson; Johan Normark; Uppsala universitet; []
    Nyckelord :African-Western Palaearctic; migratory birds; Ixodidae; Hyalomma rufipes; Ixodes; Alkhurma hemorrhagic fever virus; Anaplasma phagocytophilum; Francisella; Midichloria; Rickettsia aeschlimannii; PCR; microfluidic qPCR; metagenomics; Biologi; Biology;

    Sammanfattning : In Europe, tick-borne diseases are the most widespread and common vector-borne diseases and their geographical distribution is increasing. The dispersal of ticks depends on the movements of their vertebrate hosts. Avian hosts are more likely to be involved in long-distance range expansion of ticks due to their migration pattern.

  4. 3. Tick-Borne Infections in Humans : Aspects of immunopathogenesis, diagnosis and co-infections with Borrelia burgdorferi and Anaplasma phagocytophilum

    Författare :Marika Nordberg; Pia Forsberg; Christina Ekerfelt; Ingvar Eliasson; Christine Wennerås; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The tick-borne infectious agents, B. burgdorferi, A. phagocytophilum and the TBE-virus, can all cause clinical disease in humans and may all initially give rise to myalgia, arthralgia, headache and fever. LÄS MER

  5. 4. Ticks - ecology, new hazards, and relevance for public health

    Författare :Thérese Janzén; Monica Hammer; Patrik Dinnétz; Mona Petersson; Lars Korslund; Södertörns högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea region; eco-epidemiology; habitat; Ixodes persulcatus; Ixodes ricinus; landscape; risk; urbanization; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : Ticks and tick-borne diseases are ranking second only to mosquitoes as vectors of pathogens responsible for diseases in both humans and domestic animals. In the countries around the Baltic Sea, two medically important tick species are increasing both in range and abundance, and the public health threat posed by tick-borne diseases in this area is steadily growing.

  7. 5. Ticking off the ungulate box : the role of different ungulate species in the transmission of tick-borne pathogens

    Författare :Nannet Fabri; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    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
