Authoritative investigators active in the discovery, development, and application of biological anti-infective agents concisely review their use and potential in preventing and treating human disease. Focusing on biotherapeutic entities that have been tested in controlled studies, the prominent experts illuminate the scientific underpinnings of their therapeutic power, assess their possible risks in the treatment of infectious diseases, and outline the research needed to better define their effectiveness. In addition, they also consider how biotherapeutic agents may be genetically engineered for maximum intestinal and vaginal production of bioactive substances in vivo. Biotherapeutic Agents and Infectious Diseases brings together all the evidence needed to understand and capitalize on the considerable promise of this significant new class of biotherapeutic entities.
