  1. 1. 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

  2. 2. Ticks and Tick-borne Encephalitis Virus : From Nature to Infection

    Författare :Naveed Asghar; Magnus Johansson; Patrik Dinnétz; Travis Taylor; Södertörns högskola; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Co-occurrence; Environmental factors; Flavivirus; Ixodes ricinus; Natural foci; Non-coding region; Poly A tract; Quasispecies; Questing ticks; Scandinavia; Tick-borne encephalitis virus; Vegetation.; Environmental Studies; Miljövetenskapliga studier;

    Sammanfattning : Vector-borne diseases are an increasing global threat to humans due to climate changes, elevating the risk of infections transmitted by mosquitos, ticks, and other arthropod vectors. Ixodes ricinus, a common tick in Europe, transmits dangerous tick-borne pathogens to humans. LÄS MER

  3. 3. Tick-borne encephalitis : clinical and pathogenetic aspects

    Författare :Auksė Mickienė; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; tick-borne encephalitis;

    Sammanfattning : The aims of this study were to investigate the morbidity associated with tick-borne encephalitis (TBE) in the acute stage and at long-term follow-up, to identify the possible host risk factors for development of clinical TBE with special reference to the role of the genetic polymorphism, and to investigate neurochemical changes in the brain induced by TBE virus (TBEV) and their possible role on severity of TBE with special reference to endogenous kynurenic acid (KYNA). Paper I: Of 250 consecutively admitted patients with central nervous system (CNS) infections treated during a 1-year period, all 133 patients with TBE participated in the prospective follow-up study.

  4. 4. Emerging tick-borne pathogens: on the ecology of multiple infections in ticks and reservoir hosts

    Författare :Martin Andersson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Borrelia afzelii; ’Candidatus Neoehrlichia mikurensis’; bank vole; Myodes glareolus; multiple infection; tick-borne diseases; vector-borne diseases; competition; facilitation; qPCR;

    Sammanfattning : Most animals will encounter several more or less severe infectious diseases during their lifetime, and simultaneous infections with more than one pathogen, or several different strains of the same pathogen, are common in natural populations. Ticks transmit a wide variety of different pathogens and can also be simultaneously infected with more than one pathogen. LÄS MER

  5. 5. Host genetic risk factors to viral diseases - a double-edged sword : Studies of norovirus and tick-borne encephalitis virus

    Författare :Elin Kindberg; Lennart Svensson; Jorma Hinkula; Bertil Lindblom; Tomas Bergström; Linköpings universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Virology; Virologi;

    Sammanfattning : It is today well known that the outcome of a certain infection depends on factors of both the host and the pathogen. Studies of host genetic susceptibility to infectious diseases aim to increase the understanding of why some individuals are more susceptible than others, to a certain infection. LÄS MER
