FIGURE 3.
Bacterial growth and biofilm formation six clinical MRSA strains in the presence of sub-MIC concentrations of sub-MIC methicillin. Bacterial growth (A490 nm) is indicated along the left-hand y axes, biofilm formation (A620 nm) is indicated along the right-hand y axes, and antibiotic concentration is indicated along the x axes. Values show mean absorbance values for duplicate wells and error bars indicate range.
