The production of staphylococcal enterotoxin (SE) A to D or toxic shock syndrome toxin 1 (TSST-1) and coagulase gene typing were examined in 91 Staphylococcus aureus (S. aureus) strains isolated from nares of healthy student-nurses. Of the 91 isolates, 43 strains (47.3%) produced at least one of the SEA to SED or TSST-1. In the toxin-producing strains, TSST-1 (TSST-1, TSST-1 + SEA, TSST-1 + SEC), SEA (SEA, SEA + SEE, TSST-1 + SEA), and SEE (SEE, SEA + SEE) were detected in relatively high incidence, 46.5%, 41.9% and 34.9%, respectively. Coagulase gene typing was performed by polymerase chain reaction (PCR) amplification of coagulase gene and restriction fragment length polymorphism (RFLP) analysis of the PCR products. Among all of the isolates, there were 12 different RFLP patterns (A〜L). The 43 toxin-producing strains belonged to 8 patterns (A〜F) of the 12 patterns and pattern F (51.2%) was most frequently observed, followed by pattern B (20.9%). Pattern F was seen with most of the TSST-1- producing strains (TSST, TSST + SEA, TSST + SEC) and pattern B was observed in the SEB-producing strains.
