  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. Reproduction and health of moose in southern Sweden

    Författare :Jonas Malmsten; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Moose (Alces alces) is a highly regarded game species in Fennoscandia, where annual harvest numbers in Sweden, Norway, and Finland together exceed 200,000 animals. For successful management, knowledge about male and female reproduction is essential, as well as the extent to which disease and mortality affect the population. LÄS MER

  7. 5. Studies of Spotted Fever Rickettsia - Distribution, Detection, Diagnosis and Clinical Context : With a Focus on Vectors and Patients in Sweden

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tick-borne infections; co-infections; ticks; Ixodes ricinus; zoonosis; Rickettsia helvetica; migrating birds; Bell’s pares; erythema migrans; Rickettsia aeschlimannii; sudden deafness; facial nerve paralysis; Hyalomma marginatum; Rickettsia africae; western blot; PCR; serology; Clinical Bacteriology; Klinisk bakteriologi;

    Sammanfattning : The spotted fever rickettsia, Rickettsia helvetica, is an endemic tick-borne bacteria in Sweden. It causes infections in humans, manifested as aneruptive fever, headache, arthralgia and myalgia, and sometimes an inoculation eschar or a rash. There have also been two known cases of human infections with R. felis in Sweden. LÄS MER
