E. coli is one of the most widely studied organisms – and that may be a problem for both science and medicine

Researchers uncovered the foundations of biology by using E. coli as a model organism. But over-reliance on this microbe can lead to knowledge blind spots with implications for antibiotic resistance.

La tolérance aux antibiotiques, un problème mais aussi une piste pour comprendre et combattre la résistance aux antibiotiques

La résistance aux antibiotiques provoque des millions de morts. Les recherches montrent que la tolérance aux antibiotiques peut mener à la résistance.

Looming behind antibiotic resistance is another bacterial threat – antibiotic tolerance

Megan Keller, Cornell University

Antibiotic resistance has contributed to millions of deaths worldwide. Research suggests that any bacteria can develop antibiotic tolerance, and possibly resistance, when pushed to their limits.
