Triplicate bacterial suspensions (∼2 × 108 bacteria/ml) were separately exposed to PD (300 μM) or 10% DMSO for 30 min at 37°C. After incubation, each suspension was serially diluted and plated on blood agar plates to quantify the number of CFU per ml. Values and errors represent the means and standard deviations, respectively, of triplicate samples.
