exfoliatin

exfoliatin

 [eks-fo″le-a´tin]
an erythrogenic epidermolytic, heat-stable, acid-labile exotoxin produced by certain strains of Staphylococcus aureus (phage group II), which causes intraepidermal separation by disturbing the adhesive forces between cells in the stratum granulosum to give rise to the clinical manifestations of staphylococcal scalded skin syndrome. Called also epidermolysin.

exfoliatin

(ĕks′fō-lē-ă-tĭn)
A toxin, produced by certain strains of Staphylococcus aureus, responsible for the major dermatological changes in staphylococcal “scalded skin” syndrome in neonates and adults.
