Phage therapy is the treatment of diseases caused by bacterial infections, employing bacteriophages as anti-bacterial agents. This healing strategy is getting its second wind driven by advances in robotic screening and nanotechnology. The book provides comprehensive coverage of the topic with the currently available data exposed and critically evaluated. It examines bacterial receptors and phage anti-receptors from the point of view of development of effective therapeutic phage cocktails and considers the cytotoxicity of phages and immune reaction issues. The book also discusses possible avenues for the commercialization of phage therapy technology and its ethical and legal aspects.
