The aim of this study was to develop a vaccine against Streptococcus equi by targeting the antiphagocytic virulence factor of the bacteria, the M-Protein ( SeM18).

Introduction. The group A streptococcus, Streptococcus pyogenes, is a major human pathogen that causes infections ranging from those of the skin and pharynx that are generally self‐limiting to invasive infections with high morbidity and mortality.M proteins are dominant virulence factors of these organisms and confer the abilities to evade phagocytosis and to attach to host cells (Fischetti Mechanisms of the M protein in group A Streptococcus virulence Ghosh, Partho; Nizet, Victor / University of California San Diego: $532,847 Publications.

Genomic DNA from 22 isolates representing 14 M scretypes was selected for the study.

M is essential for GAS virulence, providing antiphagocytic functions critical to survival in human tissues 2010-06-01 · M protein of group A Streptococcus. 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 . The M protein gene (emm) encodes the cell surface M virulence protein responsible for at least 100 Streptococcus pyogenes M serotypes.

Research output: Contribution to journal › Article The M protein of Streptococcus canis (SCM) is a virulence factor and serves as a surface-associated receptor with a particular affinity for mini-plasminogen, a cleavage product of the broad-spectrum serine protease plasmin. Here, we report that SCM has an additional high-affinity immunoglobulin G (IgG) binding activity.
