Genomic DNA from 22 isolates representing 14 M scretypes was selected for the study. Primers which corresponded to the ob- served N-terminal signal M-protein expression (35), streptococci also exhibit both antigenic variation (more than 70 strains with antigenically distinct Mproteins have beendescribed) and size variation The M-protein genes of Streptococcus equi isolated from 17 outwardly healthy horses after 4 strangles outbreaks had ended, including a quarantined animal, were compared with those of S. equi isolates from 167 active cases of strangles across 4 countries.

La proteina M è fortemente antifagocitica ed è il principale fattore di virulenza per gli streptococchi di gruppo A ( Streptococcus pyogenes ). Si lega al fattore sierico H, distruggendo la C3-convertasi e prevenendo l' opsonizzazione da parte di C3b .

Microbiology An alpha-helical fibrillary molecule on the surface of group A streptococcus, which has antiphagocytic properties and contributes to streptococcal virulences. Certain M protein types of group A streptococcus (GAS) are known to cause acute post-streptococcal glomerulonephritis (APSGN).

More than 50 types of S. pyogenes M proteins have been identified on the basis of antigenic specificity. The M proteins of lower M-types (e.g., 1, 3, 5, 6, 14, 18, 19, 24) are considered rheumatogenic since they contain antigenic epitopes related to the heart muscle We applied an emm cluster typing system to group A Streptococcus strains in New Zealand, including those associated with acute rheumatic fever (ARF).

M and M-like surface proteins from group A Streptococcus (GAS) act as virulence factors and have been used in multiple vaccine candidates. M and M-like proteins are major virulence factors of the widespread and potentially deadly bacterial pathogen Streptococcus pyogenes. These proteins confer resistance against innate and adaptive immune responses by recruiting specific human proteins to the streptococcal surface. To fend off sickness, plasma cells release proteins called antibodies.
