    Sammanfattning : Lyme disease is a tick-transmitted illness caused by Borrelia burgdorferi sensu lato (s.l.), a group of spirochetes with at least three human pathogenic species, B. burgdorferi sensu stricto, B. LÄS MER

  2. 7. Biology of Borrelia garinii Spirochetes

    Författare :Pär Comstedt; Sven Bergström; Wolfram R. Zückert; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Borrelia garinii; Lyme borreliosis; birds; migration; reservoir host; complement; Ixodes ricinus; Europe; Asia; infection cycle; Molecular biology; Molekylärbiologi;

    Sammanfattning : Lyme borreliosis is a tick-transmitted infectious disease. The causative agents are spiral-shaped bacteria and the most common sign of infection is a skin rash at the site of the tick bite. LÄS MER

  3. 8. Structure and Function of the Borrelia burgdorferi Porins, P13 and P66

    Författare :Mari Bonde; Sven Bergström; Melissa Caimano; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Borrelia; P13; P66; porin; protein complex; dissemination; osmotic stress;

    Sammanfattning : Borrelia burgdorferi is an elongated and helically shaped bacterium that is the causal agent of the tick-borne illness Lyme disease. The disease manifests with initial flu-like symptoms and, in many cases, the appearance of a skin rash called erythema migrans at the site of the tick bite. LÄS MER

  4. 9. MHC polymorphism and host-pathogen interactions: The case of Borrelia in its reservoir host, the bank vole Myodes glareolus

    Författare :Kristin Scherman; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Host-pathogen interaction; Negative frequency dependent selection; Myodes glareolus; Borrelia;

    Sammanfattning : The major histocompatibility complex (MHC) class IIB genes exhibit extensive allelic polymorphism, most likely maintained by pathogen-mediated balancing selection (PMBS). PMBS may operate in the form of heterozygote advantage (HA), and/or through the interaction of pathogens and specific MHC alleles via fluctuating selection (FS) or negative frequency-dependent selection (NFDS).

  5. 10. Porins of Borrelia burgdorferi

    Författare :Marija Pinne; Sven Bergström; Magnus Höök; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lyme disease; P13; paralog; P66; channel-forming activity; porin; Medical microbiology; Medicinsk mikrobiologi;

    Sammanfattning : Borrelia burgdorferi is a pathogenic spirochete which cycles between its arthropod vector and vertebrate host. If transmitted to humans, B. burgdorferi causes Lyme disease, an infection which can impair different organs, such as the skin, joints, nervous system and heart. LÄS MER
