    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
