“At each end of the MEGA plate, there are no antibiotics. But every several centimeters in toward the center, the scientists paint bands of antibiotics of increasing potency. Each increase of antibiotic concentration is a stressor that the bacteria (they’re just regular E. coli) have to cope with. That is, the bands of increasingly powerful antibiotics (either trimethoprim or ciprofloxacin) are provoking the bacteria to evolve, outsmarting the medicines that are designed to kill them.”
