Involvement of a novel efflux system in biofilm-specific resistance to antibiotics.

Abstract excerpt

Bacteria growing in biofilms are more resistant to antibiotics than their planktonic counterparts. How this transition occurs is unclear, but it is likely there are multiple mechanisms of resistance that act together in order to provide an increased overall level of resistance to the biofilm. We have identified a novel efflux pump in Pseudomonas aeruginosa that is important for biofilm-specific resistance to a...
