  1. 16. Molecular and serological tools for clinical diagnostics of Lyme borreliosis - can the laboratory analysis be improved?

    Författare :Malin Lager; Anna J. Henningsson; Peter Wilhelmsson; Per-Eric Lindgren; Andreas Matussek; Fredrik Elgh; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Lyme borreliosis (LB) is caused by spirochetes within the Borrelia burgdorferi sensu lato complex and is the most common tick-transmitted disease in the northern hemisphere. The transmission of the spirochetes to humans in Europe is done by the Ixodes ricinus ticks, which can also transmit the relapsing fever species Borrelia miyamotoi. LÄS MER

  3. 17. Rickettsia helvetica; Detection in arthropods and human tissues and its relation to clinical disease

    Författare :Kenneth Nilsson; Björn Olsen; Uppsala universitet; []

    Sammanfattning : A relation between R. helvetica and perimyocarditis was, in two young men who died of sudden cardiac death during exercise in 1997, suggested by a seminested PCR, for three different genes, sequencing of the amplified products, documentation of a seroresponse and histopathologic changes in accordance with rickettsioses.

  4. 18. Factors in the environment, viruses and host responses affecting the epidemiology of tick-borne encephalitis virus in Northern Europe

    Författare :Elina Tonteri; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tick-borne encephalitis virus (TBEV) circulates mainly in the Ixodes ricinus and Ixodes persulcatus tick species, which serve both as hosts and vectors for the virus. Wild rodents are considered as bridges for non-viremic transmission between the ticks, which is the most important maintenance factor for TBEV. LÄS MER

  5. 19. Unraveling a novel type of severe food allergy

    Författare :Thi Anh Thu Tran; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Allergy belongs to the chronic inflammatory diseases affecting up to 30% of the population in westernized countries where food allergy has become a substantial and evolving public health issue. In the last decade, a novel type of food allergy presenting with severe allergic reactions several hours after consumption of red meat has been described. LÄS MER

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

    Författare :Martin Andersson; Biologiska institutionen; []
    Nyckelord :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
