sea-see and seg-sej, gene encoding staphylococcal enterotoxins SEA-SEE and SEG-SEJ; eta and etb, gene encoding exfoliative toxin A and B; tst, gene encoding toxic shock syndrome toxin 1; pvl, gene encoding Panton-Valentine leukocidin. P-value, two-sided P-value calculated by the chi-square or Fisher's exact test as appropriate.
