Fighting antibiotic resistance with ‘molecular drill bits’

Image
In response to drug-resistant “superbugs” that send millions of people to hospitals around the world, scientists are building tiny, “molecular drill bits” that kill bacteria by bursting through their protective cell walls. They presented some of the latest developments on these drill bits, better known to scientists as antimicrobial peptides (AMPs), at the 247th National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society.

The meeting, which features more than 10,000 scientific reports across disciplines from energy to medicine, continues here through Thursday.

One of the researchers in the search for new ways to beat pathogenic bacteria is Georges Belfort, Ph.D. He and his team have been searching for a new therapy against the bacteria that cause tuberculosis (TB). It’s a well-known, treatable disease, but resistant strains are cropping up. The World Health Organization estimates that about 170,000 people died from multidrug-resistant TB in 2012.
