Influence of Reactive Oxygen Species on De Novo Acquisition of Resistance to Bactericidal Antibiotics.

abstract：:Colistin is used to treat infections caused by multidrug-resistant gram-negative bacteria (MDR-GNB). It is administered intravenously in the form of colistin methanesulfonate (CMS), which is hydrolyzed in vivo to the active drug. However, pharmacokinetic data are limited. The aim of the present study was to characteri...
