  1. 26. Molecular analysis of Streptococcus pyogenes and its interactions with the human host

    Författare :Andreas Berge; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; complement activation; fibrinogen; IgG; M protein; C5a peptidase; streptococcal cysteine proteinase; streptokinase; t-PA; Streptococcus pyogenes; plasminogen; C1q; insertional sequence.; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Streptococcus pyogenes causes infections only in humans, from trivial tonsillitis to life-threatening conditions. One of its most important virulence factors is the M-like protein family conferring resistance to phagocytosis to the bacterium. The M-like proteins are surface exposed rod-like molecules attached to the cell wall. Each strain of S. LÄS MER

  3. 27. Interactions of human C4BP with Bordetella pertussis and Streptococcus pyogenes

    Författare :Karin Berggård; Lund Dermatologi och venereologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; M protein; antigenic variation; phagocytosis resistance; complement; C4b-binding protein C4BP ; Bordetella pertussis; Streptococcus pyogenes; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Many microorganisms have developed mechanisms to protect themselves against attack from the complement system of the host. One possible mechanism for a microorganism to evade complement attack is to bind a human complement regulator, which may allow the microorganism to down-regulate complement activation. LÄS MER

  4. 28. Epidemiology and clinical manifestations of Lyme borreliosis

    Författare :Johan Berglund; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ELISA.; Western blot; Arthritis; Ixodes ricinus; Ticks; Population based; Sweden; Prevention; Surveillance; Erythema migrans; Neuroborreliosis; Lyme arthritis; Epidemiology; Lyme borreliosis; Borrelia burgdorferi; Social medicine; Socialmedicin; samhällsmedicin; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Epidemiological and clinical characteristics of Lyme borreliosis (LB) in Sweden are described through a one year surveillance-study. The findings differed only marginally when compared to studies from the United States indicating similar clinical presentation of the disease. Incidence was 69/100. LÄS MER

  5. 29. Escherichia coli Fimbriae, Bacterial Persistence and Host Response Induction in the Human Urinary Tract

    Författare :Göran Bergsten; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; bacteriology; Microbiology; IL-8; IL-6; neutrophils; GFP; mucosal host response; Type 1 fimbriae; P fimbriae; adherence; virulence factors; regulation; deliberate colonisation; Escherichia coli 83972; Urinary tract infection; asymptomatic bacteriuria;

    Sammanfattning : Urinary tract infections (UTI) are among the most common bacterial infections in humans. Symptomatic UTIs may be acute, recurrent or chronic but the most frequent form of UTI is asymptomatic bacteruria (ABU). In ABU, the mucosa remains inert, despite the presence of large bacterial numbers in urine. LÄS MER

  7. 30. Ehrlichia in animals and humans

    Författare :Anneli Bjöersdorff; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; seroprevalence; humans; animals; granulocytic; ehrlichiosis; Ehrlichia phagocytophila; tick-borne; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Ehrlichia phagocytophila is a tick-borne pathogen of domestic animals, which has recently been acknowledged also as a human pathogen. It is a strictly intracellular bacterium, infecting granulocytes of the host, sometimes resulting in clinical disease - granulocytic ehrlichiosis - with manifestations ranging from mild flu-like conditions to severe infections with multi-organ failure and death.
