In this present study, we investigated the phenol‐soluble modulin ( psm‐mec ) mutations, the staphylococcal cassette chromosome mec (SCC mec ) types, and toxin production in 102 methicillin‐resistant Staphylococcus aureus (MRSA) isolates from the northeast and central regions of Thailand. The MRSA isolates carrying ‐7T>C psm‐mec in Type II SCC mec ( n = 18) and the MRSA isolates carrying no psm‐mec in Type IV ( n = 8) or Type IX SCC mec ( n = 4) had higher hemolytic activity against sheep erythrocytes than MRSA isolates carrying intact psm‐mec in Type III SCC mec ( n = 34), but MRSA isolates carrying no psm‐mec in Type I SCC mec ( n = 27) did not.
