Drugs fight bacteria and viruses by killing them fast, but the problem is that this eventually leads to the microbes evolving resistance to the drug. However, if another drug was given that increases the mutation rate of the microbe, perhaps this would lead them to die out, since most mutations are harmful?
Carl Zimmer interviews several scientists in The New York Times on the matter of lethal mutagenesis, and the question of whether the microbes could evolve resistance to the mutagenic drug is raised.
