The bacteria then showed an advantage in environments that contained many different antibiotics, since they easily developed mutations that made them resistant to other drugs. That means the mutant bacteria can serve as stepping stones, the authors called it, toward the development of high level resistance to multiple antibiotics.
Researchers plan to see if this phenomenon occurs in other bacter
