Comparison of the effects of subinhibitory concentrations of ciprofloxacin and colistin on the morphology of cardiolipin domains in Escherichia coli membranes.

Membrane domains characterized by unique protein and lipid composition allow for compartmentalization and regulation of various biological processes. In Escherichia coli cardiolipin domains play a key role in the dynamic organization of bacterial membranes, and their distribution depends on the stage of the cell cycle. We studied the influence of subinhibitory concentrations of ciprofloxacin and colistin on the morphology and distribution of E.
