Group A streptococcal pyrogenic exotoxins (SPE) types A, B, and C are potent nonspecific lymphocyte mitogens. The mitogenicity of these exotoxins was inhibited by gangliosides and sialic acid, whereas concanavalin A was unaffected. The capacity of bo

Production of group A streptococcal pyrogenic exotoxins (SPE) type A and C was transferred from toxigenic streptococcal strains to nontoxigenic strains by lysogeny. Lysogens were tested for SPE with Ouchterlony immunodiffusion on Todd-Hewitt agar pla

Streptococcal pyrogenic exotoxin (SPE) isolated from culture filtrates of strain NY-5 (type 10), and separated from other extracellular by differential solubility in ethanol and acetate-buffered saline, has previously been shown to exhibit a wide ran

A staphylococcal pyrogenic exotoxin was purified and characterized biochemically and biologically. The organism producing the toxin was a group I Staphylococcus aureus strain which was isolated from a vaginal infection of a patient with mucocutaneous

A fourth streptococcal pyrogenic exotoxin (SPE D) was isolated from a pathogenic strain of group A streptococci cultured from a patient with a fatal case of streptococcal fasciitis associated with hypocalcemia and ‘toxic’ syndrome. SPE D was part

Group A streptococcal pyrogenic exotoxin (SPE) types A, B, and C induced lymphocyte proliferation both specifically and nonspecifically, and the responses showed characteristics associated with both types of stimulation. Guinea pig lymphocytes from a

Several groups of streptococci were tested for production of pyrogenic exotoxins (SPE) with Ouchterlony immunodiffusion, a newly developed passive hemagglutination inhibition assay, and an assay for pyrogenicity and capacity to enhance lethal endotox
