Multiplex PCR assays for identifying agr types. (A) MDR S. aureus clinical isolates showing the agrI (441 bp), agrII (575 bp), and agrIII (323 bp) types. (B) Sensitive S. aureus clinical isolates. (C) The percentages of agr types that were identified in MDR and sensible S. aureus clinical isolates. S. aureus strain USA300 (agrI), 1749 (agrII), and ATCC 25923 (agrIII) were used as reference strains. MW, molecular weight (bp).
