Given the toxin gene profile, MRSA strains harboring SCCmec II mainly secreted enterotoxin G and I, while those harboring SCCmec III were apt to express enterotoxin A and I. Worth to be noted, among MRSA the tst gene was only found in t002-ST5-MRSA-II strains, which belonged to a epidemic clone from patients with BSI. The gene discussed is TST; the disease is bathing suit ichthyosis.
