"We are running out of antibiotics"

Scientists at Northeastern discovered a new bacteria that is Gram-negative, according to a November 19, 2019 report published by Phys.org. This is significant because gram-negative bacteria, which include E. coli and Salmonella, have an additional, outer membrane that protects them from many antibiotics. "This extra protection is why gram-negative bacteria are at the top of a list of 'priority' pathogens that need to be targeted with new antibiotics, compiled by the World Health Organization", according to the report.

"We are running out of antibiotics," says Kim Lewis, who directs the Antimicrobial Discovery Center at Northeastern, where the discovery of darobactin was made. "We need to be looking for novel compounds with no pre-existing resistance in the clinic or the population."

Yu Imai, a postdoctoral research associate in Lewis' lab, discovered the compound from Photorhabdus bacteria that live inside the gut of a nematode, a tiny parasitic worm found in soil. It's the first time, Lewis says, that the animal microbiome was found to harbor an antibiotic that promises to be useful for humans.
