    Sammanfattning : Borrelia is a Gram-negative, corkscrew-shaped bacterium transmitted by infected ticks or lice. Borreliae are subdivided into pathogens of two diseases: Lyme disease, caused mainly by B. burgdorferi, B. afzelii and B. LÄS MER

  2. 2. Role of birds in the biology of Lyme disease Borrelia

    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

  3. 3. Erythema Migrans in Primary Health Care

    Författare :Louise Bennet; Allmänmedicin och samhällsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; primary health care; ticks; gender; climate; Medicine human and vertebrates ; Medicin människa och djur ; serology; Immunology; serologi; Immunologi; transplantation; Infections; Infektioner; General practice; medicinsk utbildning; medical training; Allmän medicinsk utövning; Lyme borreliosis; erythema migrans; incidence; Borrelia afzelii; Borrelia garinii;

    Sammanfattning : Lyme borreliosis (LB) is the most common vector-borne disease in the northern hemisphere, and southern Sweden is a highly endemic area. In over 70% of the cases, LB is represented by the non-disseminated cutaneous form erythema migrans (EM). LÄS MER

  4. 4. 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

  5. 5. 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).
