title: Limulus amebocyte lysate reaction with streptococcal pyrogenic exotoxin.
abstract: Three immunologically distinct pyrogenic exotoxins derived from group A streptococci were found to cause coagulation of limulus amebocyte lysate. These exotoxins were shown to be several thousand times less active for lysate coagulation than gram-negative endotoxin.
