New antibiotic that kills drug-resistant bacteria found in technician's garden


The molecule targets bacteria in a way that other drugs don’t.

Researchers have discovered a new antibiotic molecule that targets a broad range of disease-causing bacteria — even strains resistant to commercial drugs — and is not toxic to human cells 1. The discovery shows that “there is terrifically interesting stuff hiding in plain sight”, says Kim Lewis, a microbiologist at Northeastern University in Boston, Massachusetts, who was not involved in the research. “The antibiotic-resistance crisis is an existential threat to medicine,” says Gerry Wright, a chemical biologist at McMaster University in Hamilton, Canada, and a co-author of the study, which is published in Nature today.
