New class of antibiotic could turn the tables in battle against superbugs
The powerful antimicrobial teixobactin was discovered using a new technique that could speed up the discovery of new antibiotics to tackle resistance
Scientists have discovered a new class of antibiotic using a revolutionary procedure hailed as a game changer in the hunt for medicines to fight drug-resistant infections. The antibiotic, called teixobactin, kills a wide range of drug-resistant bacteria, including MRSA and bugs that cause TB and a host of other life-threatening infections.
It could become a powerful weapon in the battle against antimicrobial resistance, because it kills microbes by blocking their capacity to build their cell walls, making it extremely difficult for bacteria to evolve resistance.
“Teixobactin kills exceptionally well. It has the ability to rapidly clear infections,” said research leader Kim Lewis, director of the Antimicrobial Discovery Center at Northeastern University in Boston, US.
