The Scientist Thwarting Persistence Bacterial antibiotic resistance is widespread and presents ongoing challenges in treating infections. A less widely known—but equally challenging—problem is antibiotic tolerance, where bacteria called persisters are not sensitive to antibiotics because the drugs’ targets are inactive in these dormant cells. Kim Lewis’s group at Northeastern University in Boston, Massachusetts, had previously shown that persisters give biofilms their drug-tolerant properties. Now, […]
