Susceptibility of the different S. epidermidis populations to vancomycin, tetracycline and rifampicin. Exponential (exp) or stationary (stat) phase planktonic (P) cells, cells from disrupted biofilms (BF) or Brc were collected at each time point indicated and their concentration adjusted to 1 × 10⁷ cells/mL in TSB_0.25 %G or TSB_0.25 %G containing each antibiotic and incubated for 2 h at 37 °C and 120 rpm. Bars represent the average ± standard deviation of three independent experiments. Statistical significance was determined using One-way ANOVA and Dunnett’s Multiple Comparison test. *P < 0.05, **P < 0.01, ***P < 0.001
