    Sammanfattning : Streptococcus pyogenes is a common human pathogen causing mild infections such as tonsillitis and pharyngitis, but is also the cause of life-threatening conditions. To be able to infect the human host, S. pyogenes express different virulence factors. The surface-expressed M protein is a major virulence factor of S. LÄS MER

  3. 12. On the induction of inflammatory reactions by Streptococcus pyogenes

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; virology; bacteriology; Microbiology; Streptococcal collagen-like surface protein; M protein; Inflammation; Streptococcus pyogenes;

    Sammanfattning : Streptococcus pyogenes is an important human pathogen that causes significant morbidity and mortality worldwide. In order to successfully infect the human host, S. pyogenes is equipped with tools that modulate the human immune defence. LÄS MER

  4. 13. Streptococcus pyogenes secreted enzymes interacting with the human host

    Författare :Mattias Collin; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; RNA fingerprinting; Streptococcus pyogenes; Clinical biology; immunoglobulins; Klinisk biologi; autoimmunity; endoglycosidase; cysteine proteinase; glycosylation;

    Sammanfattning : Streptococcus pyogenes is one of the most common bacteria infecting humans. One of the factors contributing to the disease-causing properties is the secreted streptococcal cysteine proteinase, SpeB, which degrades several host proteins in connective tissue and circulation.

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; M protein; Streptococcus pyogenes; Streptolysin O; The complement system; Neutrophils; Biomedical sciences; Biomedicinska vetenskaper; General biomedical sciences; Biomedicinska vetenskaper allmänt ; Microbiology; transplantation; Immunology; serology; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; Immunologi; serologi; Infections; Infektioner; Clinical biology; Klinisk biologi; bacteriology;

    Sammanfattning : Streptococcus pyogenes is an important human pathogen frequently colonizing the throat and skin of humans. To facilitate colonization and spread and to avoid the host immune defence, streptococci are endowed with a variety of virulence factors, two of which are investigated in this thesis namely streptolysin O (SLO) and M protein.

  7. 15. Streptococcus pyogenes and its interactions with the human host

    Författare :Ulrika Ringdahl; Institutionen för immunteknologi; []
    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
