National Geographic: A new antibiotic that resists resistance
National Geographic - 01/07/2015
Since humans started making antibiotics for ourselves in the 1940s, bacteria have evolved to counteract our efforts. They are now winning. There are strains of old foes that withstand everything we can throw at them. Meanwhile, our arsenal has dried up. Before 1962, scientists developed more than 20 new classes of antibiotics. Since then, they have made two.
More, hopefully, are coming. A team of scientists led by Kim Lewis from Northeastern University have identified a new antibiotic called teixobactin, which kills some kinds of bacteria by preventing them from building their outer coats. They used it to successfully treat antibiotic-resistant infections in mice. And more importantly, when they tried to deliberately evolve strains of bacteria that resist the drug, they failed. Teixobactin appears resistant to resistance.
