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.

Streptococcal m protein

Despite the extensive 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. Streptococcal M protein extracted by nonionic detergent. I. Properties of the antiphagocytic and type-specific molecules.

Ultracentrifuge studies reveal that the M molecules exist as stable dimers; circular dichroism spectra indicate that the molecules contain about 70% alpha helix; and fiber x-ray diffraction diagrams show the characteristic M protein. The soluble M1 protein exhibits pro-inflammatory properties including activation of platelets, platelet-leukocyte complex formation and modulation of the inflammatory responses of neutrophils and monocytes. The aim of this thesis is to further elucidate the immunomodulatory role of platelets activated by streptococcal M proteins. STREPTOCOCCAL M PROTEIN EXTRACTED BY NONIONIC DETERGENT II. Analysis of the Antibody Response to the Multiple Antigenic Determinants of the M-Protein Molecule* BY VINCENT A. FISCHETTI~ (From The Rockefeller University, New York 10021) Streptococcal M proteins are antiphagocytic molecules varying immunologi- Streptococcal M protein, the antiphagocytic molecule on the surface of the organism, was previously found to exhibit extensive size heterogeneity between as well as within M serotypes.

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.

Attempts to use Mprotein for development of an anti-streptococcal vaccine havebeen complicated bythe exten-sive variability of the Mantigen and by the inability to demonstrateextensivecross-reactivity Guanidine Extraction of Streptococcal MProtein HAROLDRUSSELL* AND RICHARD R. FACKLAM Centerfor Disease Control, Atlanta, Georgia 30333 Received for publication 10 February 1975 Anewmethod of extracting Mprotein from streptococcal cell walls has been presented.
