Abstract
P. aeruginosa is a ubiquitous Gram-negative opportunistic pathogen associated with a wide array of life-threatening acute and chronic infections. However, the improper and excessive use of antibiotics has contributed to the increasing emergence of multidrug-resistant (MDR) P. aeruginosa, even colistin-resistant strains, which presents a major challenge to clinical anti-infection treatment. Resveratrol, a naturally occurring polyphenolic antioxidant, can effectively slow down or avoid the occurrence and development of bacterial resistance and is expected to offer a promising strategy to overcome bacterial infections. In this study, colistin/resveratrol combination could synergistically damage the bacterial cell membrane, thereby inducing cell lysis while addressing the emergence of drug resistance. Moreover, this combination therapy may provide an efficient alternative pathway to combat the colistin-resistant P. aeruginosa in clinical practice.
