Fig. 1From: Sub-inhibitory concentrations of oxacillin modify the expression of agr locus in Staphylococcus aureus clinical strains belonging to different clonal complexesEffect of subMICs of oxacillin over RNAIII (a) and agrA (b) expression levels under oxacillin subMICs exposure in stationary growth phase. The expression levels of both agrA and RNAIII genes were determined by qRT–PCR experiments (three different experiments). The results are expressed as the n-fold variation of RNAIII (A) and agrA (B). An asterisk indicates a significant difference (P < 0.05)Back to article page
