How resistance-nodulation-division (RND) efflux pumps contribute to virulence

In Gram-negative bacteria, multi-subunit efflux pumps transport molecules across the inner membrane, periplasm, and outer membrane to the extracellular environment. These efflux pumps include the Resistance-Nodulation-Cell Division (RND) superfamily, which utilize the membrane proton motive force to export a wide range of substrates against a concentration gradient.
