Fig. 1. DMSO but not Cyrene™ protects ESKAPE pathogens from stress-induced ROS-mediated programmed cell death. Exponentially growing cultures were treated with 2× MIC ciprofloxacin for 90 min, followed by immediate plating onto LB agar lacking or containing 2% (vol/vol) DMSO or Cyrene™. After incubation at 37 °C overnight, colonies were counted. Shown are the average values from experiments carried out three times. Error bars indicate deviations as standard errors of the mean.
