Figure 3From: Contribution of SecDF to Staphylococcus aureusresistance and expression of virulence factorsEffect of secDF inactivation on resistance profiles. (A) Gradient plates with increasing concentrations of β-lactam and glycopeptide antibiotics. Oxacillin was tested with methicillin sensitive and methicillin resistant strain Newman, the latter carrying the plasmid pME2 containing the mecA gene. (B) Gradient plates with increasing concentrations of the RND substrates acriflavine, ethidium bromide and SDS.Back to article page
