a
S. aureus strains were all isolated from different patients with staphylococcal scalded skin syndrome. Isolates were confirmed to be S. aureus by their ability to coagulate citrated rabbit plasma and to produce a clumping factor (6).
b
eta and etb genes were detected by PCR assay as previously described (6).
c
agr groups were determined by PCR sequencing analysis.
