The M protein of group A Streptococcus is a key virulence factor and a clinically relevant strain identification marker. Virulence: Vol. 2, No. 5, pp. 402-412. Als M-Protein bezeichnet man einen Virulenzfaktor von Streptokokkenarten der Lancefield-Einteilung-A (Hauptvertreter: Streptococcus pyogenes).Es zählt zu den bedeutendsten Oberflächenantigenen dieser Arten. M-protein expression (35), streptococci also exhibit both antigenic variation (more than 70 strains with antigenically distinct Mproteins have beendescribed) and size variation Briefly, M proteins bind many regulatory elements of the complement system including Factor H (Fischetti, Horstmann and Pancholi 1995; Gustafsson et al. 2013), factor H-like protein 1 (Johnsson et al.

La clave del poder de la 8 Jul 2019 Plasminogen (Plg)-binding M protein (PAM) is a group A streptococcal cell surface receptor that is crucial for bacterial virulence. Previous av U Ringdahl · 2002 — Abstract: We have found that a set of group A streptococcal strains, primarily associated with skin infections, express surface-associated M proteins that bind Here we analyse this problem for the antiphagocytic M protein of Streptococcus pyogenes, using the opsonizing capacity of antibodies to estimate their ability to The major virulence factor of S. pyogenes is the M protein, a fibrillar surface protein that prevents phagocytosis and contributes to virulence also M-protein, superantigener (sAg) och cystein protease (CP) är virulensfaktorer hos S. pyogenes som är av av särskild betydelse vid invasa infektioner.
