Malthusian parameter and pairwise competition estimates of fitness for S. aureus ciprofloxacin and fusidic acid susceptible and resistant mutants (A) Growth rates estimates from three S. aureus strains using a Bioscreen (BS, red bar) and BioTek (BT, black bar) plate readers. SA is an antibiotic sensitive strain, SA-CIP is a ciprofloxacin resistant strain and SA-FUS is a fusidic acid resistant strain. (B) Malthusian parameters relative to wild type (SA), (Bioscreen red BioTek black) and Bootstrap-calculated confidence intervals. (C) Changes in the ratio of the antibiotic resistant mutants and SA WT in pairwise competition SA-CIP (black) and SA-FUS (blue), mean and standard deviation of the ratios from three independent competition experiments.
