Antibiotics and antimicrobial agents, have been used for over 50 years to treat patients who have infectious diseases. These drugs have greatly reduced illness and death from infectious diseases. However, these drugs have been used so widely and for so long that the infectious organisms the antibiotics are designed to kill have adapted to them, making the drugs less effective. Editor Debra A. Miller has collected essays that provide readers with a spectrum of views on issues relating to drug resistant infections. The writings represent divergent viewpoints on issues, such as the link between agricultural use of antibiotics and resistant infections.
