Mechanisms of quinolone action and resistance: where do we stand?

Abstract excerpt

Quinolone antibiotics represent one of the most important classes of anti-infective agents and, although still clinically valuable, their use has been compromised by the increasing emergence of resistant strains, which has become a prevalent clinical problem.
