Abstract
Streptococcus pyogenes encodes multiple virulence factors and their presence is often related to the severity of the disease. We designed the system of four low-volume multiplex PCR reactions to detect genes encoding 20 virulence factors: spd3, sdc, sdaB, sdaD, speB, spyCEP, scpA, mac, sic, speL, speK, speM, speC, speI, speA, speH, speG, speJ, smeZ, and ssa. Classification of strains based on the virulence factors absence or presence correlates with PFGE MLST and emm typing results. The typing/detection system is fast and cost-effective, can be used to detect GAS virulence factors and as a rapid tool to effectively differentiate between strains.
