  1. 1. Studies on hereditary C2 deficiency: Frequent occurrence of severe infections, atherosclerosis and rheumatological manifestations

    Detta är en avhandling från Department of Medical Microbiology, Lund University

    Författare :Göran Jönsson; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; serology; Immunology; mykologi; bakteriologi; virologi; Mikrobiologi; mycology; Complement; Complement C2 deficiency; Infectious diseases; Atherosclerosis; SLE; Autoantibodies; GM allotypes; Immunodeficiency state; Medicine human and vertebrates ; Medicin människa och djur ; Microbiology; virology; bacteriology; Immunologi; serologi; Infections; Infektioner;

    Sammanfattning : The complement system is a part of the innate immunity and is essential in the defence against microorganisms. Hereditary C2 deficiency (C2D) is one of the most common complement deficiency states with an estimated prevalence of 1:20,000 in persons of Western descent. LÄS MER

  2. 2. Staphylococcus aureus bacteremia. Serological findings, phenotypic and genotypic characteristics of S. aureus strains

    Detta är en avhandling från Department of Infectious Diseases, Östersund Hospital, S-831 83 Östersund, Sweden

    Författare :Ulf Ryding; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infections; Infektioner; serology; collagen binding protein.; Staphylococcus aureus bacteremia;

    Sammanfattning : The diagnosis of S. aureus infections is most often based on culture of the organism from various body sites. However, cultures could be false negative due to e.g. LÄS MER

  3. 3. Streptococcus pyogenes and its interactions with the human host

    Detta är en avhandling från Ulrika Ringdahl, Bardisangränden 3 E, 226 48 Lund

    Författare :Ulrika Ringdahl; [2002]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infections; mykologi; virologi; bakteriologi; M protein; Streptococcus pyogenes; plasminogen; fibrinogen; phagocytosis; platelet; Microbiology; bacteriology; virology; Mikrobiologi; mycology; Infektioner; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : We have found that a set of group A streptococcal strains, primarily associated with skin infections, express surface-associated M proteins that bind plasminogen and plasmin with high affinity. The binding is mediated by a common 13 amino acid internal repeated sequence located in the NH2-terminal surface-exposed portion of these M proteins. LÄS MER

  4. 4. Pathogen-host interactions at the surface of Streptococcus pyogenes

    Detta är en avhandling från KFS AB

    Författare :Patrik Nyberg; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infektioner; Infections; C3a; LL-37; antimicrobial peptide; GRAB; alpha-2-macroglobulin; proteolysis; SpeB; internalization; virulence; protein F1; Streptococcus pyogenes; fibronectin;

    Sammanfattning : The bacterial surface can be thought of as the interface where pathogenic bacteria encounter the human host. Interactions between bacterial surface proteins and human proteins are important determinants of the eventual outcome of infection. LÄS MER

  5. 5. Interactions between streptococcal M proteins and human plasma proteins

    Detta är en avhandling från Department of Laboratory Medicine, Lund University

    Författare :Charlotta Sandin; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infektioner; Infections; innate immunity; Streptococcus pyogenes; phagocytosis resistance;

    Sammanfattning : Streptococcus pyogenes is a common human pathogen, which causes a variety of diseases. A major virulence factor of S. pyogenes is the surface-associated M protein, which mediates resistance to phagocytosis. Several studies indicate that M proteins inhibit complement deposition and thereby phagocytosis. LÄS MER
