An erythrogenic toxin is a toxin produced by strains of Streptococcus pyogenes, the primary cause of scarlet fever.[1][2] Past studies have shown that multiple variants of erythrogenic toxins may be produced, depending on the strain of S. pyogenes present in the host. A small percentage of strains may not produce a detectable toxin at all.[3] The erythrogenic toxin is also referred to in the literature as Streptococcal Pyrogenic Exotoxin types A, B, and C (SPE-A, SPE-B, SPE-C). (Patrick M Schlievert, Journal of Infectious Diseases, 1989.)

- Streptococcal pyrogenic exotoxin B (SpeB) is an important virulence factor of group A streptococci (GAS) and inactivation of SpeB results in the significantly decreased virulence of the bacterium. The protein is secreted as an inactive zymogen of 40 KDa (SpeBz) and undergoes proteolytic truncation t
