The emergence of bacteria resistant to multiple antibiotics has become a serious threat to public health and is considered one of the greatest challenges for contemporary medicine. Phage therapy - the use of bacteriophages as anti-bacterial agents - may offer an alternative treatment for bacterial infections. Phages have many potential applications in human medicine, as well as in dentistry, veterinary science, agriculture, and food protection. Written by internationally recognized experts from leading centers involved in phage research and phage therapy, this book provides comprehensive coverage of the topic with a focus on current research and emerging applications. The book opens with chapters covering the general characteristics of bacteriophages and the basic concepts of phage therapy. Further topics include: the pharmacology of phage therapy * bacterial resistance * non-bactericidal effects of phages * main applications of bacteriophages in clinical medicine * plant pathosystems * animal production * food protection * biofilm control * regulatory and intellectual property aspects of phage therapy. Although the book focuses on applications of virulent bacteriophages, it also discusses genetically-engineered phages, phages as delivery vehicles for other antimicrobials, as well as phage lysins. It will be an essential reference for anyone interested in phage therapy, antibacterial resistance, antimicrobial development, bacteriophage research, biocontrol, and biodetection.
