Prime candidates are the streptococcal superantigens (SAgs), a family of highly mitogenic proteins secreted individually or in certain combinations by many Streptococcus pyogenes strains (7 10), although other virulence factors, such as streptolysin O and various cell wall antigens can also cause toxic shock (11).
