    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. 7. Cellular receptors for species B adenoviruses

    Författare :Marko Marttila; Niklas Arnberg; Göran Wadell; Tomas Bergström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adenovirus; CD46; CD80; CD86; Species B; Receptor; Internalization; Infection; Tropism; Virology; Virologi;

    Sammanfattning : Adenoviruses belong to the most common human pathogens. The severity of infection varies greatly, from subclinical to lethal, depending on the virus type and immune status of the infected host. The 51 known human adenovirus serotypes are divided into six species (A-F) based on characteristics such as tropism. LÄS MER

  4. 8. Quantitative detection of bacterial DNA in whole blood in bloodstream infection

    Sammanfattning : There is sex-bias in morbidity and mortality from infectious diseases. Infections kill more men than women and several studies have pointed out differences in the immune system as a reason. The sex hormones estrogen, progesterone and testosterone all shape the effect of the immune response on multiple levels. LÄS MER

  7. 10. Immunometabolic reprogramming during suppressive HIV-1 infection

    Författare :Sara Svensson Akusjärvi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Since the implementation of antiretroviral therapy (ART), infection with human immunodeficiency virus type-1 (HIV-1) has been transformed into a chronic lifelong condition. The main obstacle for a HIV-1 cure is the persistence of latently infected cells in viral reservoirs. LÄS MER
