Abstract:The surface of Streptococcus pyogenes (GAS) is studded with virulence determinants, with the most abundant being the characteristic M-protein used to serotype various strains of the bacterium. There are >250 strains of GAS serotypically distinguished by their M-proteins. Major pathogenic mechanisms of GAS require that this microorganism hijacks host components for survival, many of which are involved in hemostasis. One of these processes involves the binding of human host plasminogen (hPg) to an abundant GA… Show more
