While the ways in which the cells of drug resistant bacteria become resistant are understood at the cellular level, until now, the bacteria's survival strategies at the population level remained unclear. A new study at Boston University and Harvard University reveals that a surprisingly small percentage of bacteria actually become highly resistant supermutants. In fact, most of the bacteria in their study survived without being resistant to the effective dose of antibiotics in the environment.
