Mar 17, 2006 Streptococcus pyogenes is a Gram-positive bacterium that causes several diseases, including acute tonsillitis and toxic shock syndrome.

Shangwei Wu, in Molecular Medical Microbiology (Second Edition), 2015. M Protein-Mediated Invasion. M protein is an important virulence factor expressed on the surface of S. pyogenes and plays multiple roles in streptococcal infection, including resistance to phagocytosis, adherence to epidermal keratinocytes, microcolony formation and invasion of epithelial cells [192]. M protein may stand for viral matrix protein as in the M1 protein of the influenza virus. M protein may be used in referring to a specific bacterium, streptococcus pyogenes.

Infection and immunity. 2002;70(5):2734–8. Epub 2002/04/16. pmid:11953422; PubMed Central PMCID: PMC127950. A resurgence of invasive streptococcal diseases and rheumatic fever has appeared in outbreaks over the past 10 years, with a predominant M1 serotype as well as others identified with the outbreaks.

The protein expression of Streptococcus pyogenes is significantly influenced by The immunoglobulin M-degrading enzyme of Streptococcus suis, Ide(Ssuis),

M protein is an important virulence factor expressed on the surface of S. pyogenes and plays multiple roles in streptococcal infection, including resistance to phagocytosis, adherence to epidermal keratinocytes, microcolony formation and invasion of epithelial cells [192]. M protein is a virulence factor that can be produced by certain species of Streptococcus. [1] Viruses, parasites and bacteria are covered in protein and sugar molecules that help them gain entry into a host by counteracting the host's defenses. One such molecule is the M protein produced by certain streptococcal bacteria.

Group A Streptococcus (GAS) is a human-specific pathogen, first characterised by Lancefield , which is associated with a wide spectrum of diseases ranging from uncomplicated infections to severe invasive diseases and debilitating sequelae such as rheumatic fever and acute glomerulonephritis . Interaction of the M-protein of group A Streptococcus (GAS) with its numerous host binding partners might assist the bacteria in evading host immune responses. Although the extensive diversity of this protein has been highlighted by different GAS typing schemes, most of the structural and functional information has been obtained from a limited number of types.

The M protein gene (emm) encodes the cell surface M virulence protein responsible for at least 100 Streptococcus pyogenes M serotypes. emm typing is based on sequence analysis of the portion of the emm gene that dictates the M serotype. The hypervariable sequence associated with M serospecificity is adjacent to an amplifying primer sequence Streptococcus pyogenes is a Gram-positive bacterium that causes several diseases, including acute tonsillitis and toxic shock syndrome. The surface-localized M protein, which is the most extensively studied virulence factor of S. pyogenes, has an ∼50-residue N-terminal hypervariable region (HVR) that plays a key role in the escape of the host immunity.
