[Transformation of endogenous reactive oxygen species participates into bacterial antibiotic resistance].

A growing body of diversified antibiotic resistances raises a significant challenge to anti-infection clinical therapeutics. The emergence of superbugs carrying MCR-1/2 or NDM-1 determinants underlines the importance and urgency in elucidation of molecular mechanisms shared by antibiotic resistances. It is aware that different classes of bactericidal antibiotics consistently stimulate the production of deleterious reactive oxygen species (ROS), which are accompanied with metabolic disturbance. The different destinations of ROS determine its consequence on bacterial fate. Here, we review antibiotic-induced production, progression and transformation of ROS, as well as its role in the development of antibiotic resistance. Additionally, we anticipate that mesosome-like structures-aided exclusion of hydrogen peroxide might represent a previously-unknown mechanism for antibiotic resistance. This mini-review is aiming to present an update overview on antibiotic resistance and provide clues to the development of novel antibiotics.
