Antibiotics are supposed to wipe out bacteria, yet the drugs can sometimes hand microbes an unexpected advantage.
A new study from Rutgers Health shows that ciprofloxacin, a staple treatment for urinary tract infections, throws Escherichia coli (E. coli) into an energy crisis that saves many cells from death and speeds the evolution of full-blown resistance.
"Antibiotics can actually change bacterial metabolism," said Barry Li, a student at Rutgers New Jersey Medical School pursuing a dual doctoral degree for physician-scientists and the first author of the paper published in Nature Communications. "We wanted to see what those changes do to the bugs' chances of survival."
