  4. 2. Mechanisms of phagocytosis resistance in Streptococcus pyogenes

    Author : Heike Kotarsky; Lund Pediatrik; []

    Abstract : A distinguishing feature of Streptococcus pyogenes (GAS) is their ability to resist phagocytosis in whole human blood in the absence of type-specific antibodies, a property that is dependent on the expression of the surface associated M proteins. A common characteristic of M proteins is their interaction with a variety of host proteins including the complement regulatory protein factor H (FH) and fibrinogen that plays a key role in coagulation.

    Abstract : In this thesis we have used P fimbriated E. coli as a model to investigate the mechanisms of bacterial recognition and cell activation by the urinary tract (UT) epithelium. We show that Toll like receptor 4 (TLR4) is crucial for the recognition and host response to P fimbriated E. coli. READ MORE

  6. 4. Role of Neutrophils and Innate Immune Mechanisms in Urinary Tract Infections

    Abstract : Urinary tract infections (UTI) are among the most common infections in man. Despite their prevalence, information on the molecular mechanisms defects that explain the increased susceptibility to disease are lacking. READ MORE

    Abstract : Background Coagulase-negative staphylococci (CoNS) and in particular Staphylococcus epidermidis have emerged as major pathogens primarily causing nosocomial infections in patients with indwelling medical devices. These infections are often caused by multidrug-resistant strains of S. epidermidis (MDRSE). READ MORE
