FIG. 2.

Effects of subinhibitory concentrations of amoxicillin, gentamicin, and moxifloxacin on the hemolytic activities of nine S. aureus strains. S. aureus cultures were grown in the absence (black bars) or presence (open bars) of two subinhibitory concentrations (Table 1) of amoxicillin, gentamicin, or moxifloxacin. Thereafter, culture supernatants were subjected to a rabbit erythrocyte hemolysis assay. Bars represent mean values of three or more independent experiments.
