In this totally revised and updated edition of the classic primer on the misuse of antibiotics, Dr. Stuart Levy reveals how our cavalier and naïve attitude about the power of antibiotics can have -and already has had-dire consequences. He explains that we are currently witnessing a massive evolutionary change in bacteria. This build-up of new antibiotic-resistant bacteria in individuals and the environment, mixed with our overzealous use of antibiotic soaps and the unregulated dispensing of antibiotics worldwide, is leading us into a dangerous territory where our "miracle" drugs will no longer help.
