Abstract

Group A streptococcal pyrogenic exotoxins A, B, and C (also known as scarlet fever toxins and erythrogenic toxins) were evaluated for relatedness to another streptococcus-derived lymphocyte mitogen, blastogen A. Streptococcal pyrogenic exotoxin A and blastogen A were immunologically cross-reactive and shared the same molecular weight, N-terminal amino acid sequence, and capacity to stimulate rabbit splenocyte proliferation nonspecifically.
