Nonspecific T-lymphocyte mitogenesis by pyrogenic exotoxins from group A streptococci and Staphylococcus aureus

Abstract
Group A streptococcal pyrogenic exotoxins types A, B, and C and staphylococcal pyrogenic exotoxin were shown to be potent nonspecific T-lymphocyte mitogens. Adherent cell populations did not significantly affect the nonspecific mitogenicity.
