21. Evolutionary and functional studies of protein H: a surface molecule of Streptococcus pyogenes
Abstract : Several bacterial species express surface proteins with affinity for the Fc part of human IgG. This thesis describes evolutionary and functional studies of protein H, an IgGFc-binding surface protein of the human pathogen Streptococcus pyogenes. READ MORE

22. Phagocytosis by neutrophils - studies on phagosome dynamics and membrane traffic modulation by Streptococcus pyogenes
Abstract : Neutrophils are our most numerous and deadly white blood cells and without them we would succumb quickly to infections by pathogens. The main mechanism that the neutrophils employ for our protection is phagocytosis, where they eat and enclose their target inside a membrane-bound organelle, the phagosome. READ MORE

23. Streptococcus pyogenes : life within the macrophage
Abstract : Streptococcus pyogenes is a versatile human pathogen causing a wide array of diseases ranging from uncomplicated throat and skin infections to invasive life- threatening diseases with a mortality rate of up to 60%. It is ranked number nine on the list of worst infectious diseases world wide, causing 500 000 deaths yearly. READ MORE

24. Interactions between Streptococcus pyogenes and the human immune system, with special reference to C4b-binding protein
Abstract : The ability of many pathogenic microorganisms to cause infection is dependent on their ability to evade attack by the complement system of the host. One mechanism by which microorganisms may avoid complement attack is to bind complement inhibitory molecules present in the host. READ MORE

25. Studies on cell wall-attached proteins of Streptococcus pyogenes
Abstract : Cell wall-attached proteins (CWPs) are important for the virulence of Gram-positive bacteria, but are also targets for the host immune system. CWPs have a conserved COOH-terminal region, responsible for cell wall-sorting. A pattern based on this conserved region was developed. READ MORE
