Scientists have found a new way to kill antibiotic-resistant bacteria. The new approach disarms their natural defense mechanism, making existing antibiotics more lethal.
The study, conducted in lab dishes and mice, offers a promising strategy for taking down so-called superbugs without needing to make brand-new You want to make the already existing antibiotics with good safety profiles more potent, and with the help of a few newfound chemicals, the research team did just that, said senior author Evgeny Nudler, a professor of biochemistry at the New York University Grossman School of Medicine and an investigator with the Howard Hughes Medical Institute.
