  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. Molecular characterization of the Tick-borne encephalitis virus : Environments and replication

    Författare :Wessam Melik; Magnus Johansson; Sonja Best; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tick-borne encephalitis virus; molekylärgenetik; Molecular Genetics;

    Sammanfattning : The flavivirus genus is of major concern for world morbidity and mortality and includes viruses causing both encephalitic as well as hemorrhagic diseases. The incidence of Tick-borne encephalitis is increasing in many European countries and several reports have emphasized the expansion of the main vector, Ixodes ricinus. LÄS MER

  4. 18. 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.

  5. 19. 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

  7. 20. A STING from a Tick : Epidemiology, Ecology and Clinical Aspects of Lyme Borreliosis

    Författare :Peter Wilhelmsson; Per-Eric Lindgren; Pia Forsberg; Sven Bergström; Christina Ekerfelt; Jeremy S. Gray; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Lyme borreliosis (LB) is the most common tick-borne disease in the Northern Hemisphere and the number of LB cases is increasing. The infection is caused by spirochetes belonging to the Borrelia burgdorferi sensu lato complex, and is, in Europe, transmitted to humans by Ixodes ricinus ticks. LÄS MER
