  1. Values are given as n (%)
  2. PFGE pulsed-field gel electrophoresis, SCCmec staphylococcal chromosomal cassette, PVL Panton–Valentine leukocidin, MLST multilocus sequence typing
  3. aA significant difference was found between the community-associated and healthcare-associated isolates in respect to PFGE D, PFGE A, and PFGE F clones (p < 0.001)
  4. bA significant difference was found between the community-onset and hospital-onset isolates in terms of the third clone (p = 0.022)
