Final answer:
The toxin responsible for Staphylococcal scalded skin syndrome (SSSS) caused by Staphylococcus aureus is exfoliative toxin, leading to severe skin peeling and erythema.
Step-by-step explanation:
The toxin produced by Staphylococcus aureus that causes the 'scalded-skin syndrome' is known as the exfoliative toxin. This toxin leads to a superficial skin infection called Staphylococcal scalded skin syndrome (SSSS), primarily seen in young children. The exfoliative toxin causes initial erythema, or redness of the skin, followed by severe peeling that resembles scalding. Diagnosis of SSSS involves skin examination, blood tests for elevated white blood cell counts, culturing, and other methods. Treatment often includes administering intravenous antibiotics and fluid therapy.
