Viruses as disease activators are the dominant topic of the current debate. Still certain viruses can heal, when they are used against specific bacteria. With respect to the antibiotics crisis, virus therapy is a hope in the fight against bacterial infections. They were already popular before the discovery of penicillin. In his interesting medicine report, Thomas Häusler tells the story of this therapy, which has mainly survived in a Georgian institute. He writes about exciting research, human destinies and how this therapy is being rediscovered also here in the Western world, though strictly scientific evidence of its efficacy is still not available. His book shows the possible contribution of the virus therapy to the containment of the antibiotics crisis.
