Figure 3.
Time-kill curves of oxacillin shown by plots of mean values for the log10 of the numbers of CFU/mL versus time for two representative clinical S. aureus WTs (a,c) and corresponding SCVs (b,d) tested against oxacillin. The threshold implicates a ≥3 − log10 decrease in CFU/mL. Time-kill curves for each strain were performed in triplicate (mean ± standard deviation). Asterisks denote statistical difference of the respective concentration of oxacillin used (defined by matching colors) with respect to the untreated growth control at 1 h; p ≤ 0.001 by one-way ANOVA.
