*relative pvl expression in comparison with 526 (USA300/ST8) isolate; †isolate sequenced at the present study; ST - Sequence type; SCCmec - Staphylococcal Cassete Chromosome mec; SD - standard deviation; na - not applicable (methicillin-sensitive isolate). The experiments were performed in three independent triplicates.
