ETA, exfoliative toxin A; ETB, exfoliative toxin B; ETD, exfoliative toxin D; PVL, Panton‐Valentine leucocidin; TSST, toxic shock syndrome toxin.

Seven more mecA (−) and mecC (−) strains are not included because they have decreased sensitivity to oxacillin that should be more widely studied. Two of these strains were TSST (+) and 1 ETD (+).
