“Checkerboard analysis indicated … synergistic effect between resveratrol … polymyxin B ; the optimal drug concentration for different bacteria was different, that of resveratrol ranging from 32 μg/mL to 128 μg/mL. Subsequent time-kill experiments showed that a combination of polymyxin B and resveratrol was more effective in killing bacteria.”
“Conclusions Our in vitro studies have shown that resveratrol can increase the sensitivity of MDR bacterial strains to polymyxin B , suggesting a potential new approach to the treatment of MDR infections.”
“MICs against polymyxin B in the isolates tested were significantly reduced by the addition of resveratrol.”
