ABSTRACT
Significance Novel antibiotics are urgently needed to treat the ever-increasing number of drug-resistant infections. Venoms constitute a treasure trove novel potential medicines. Here, we converted peptide derived from venom into potent antimicrobials capable resolving otherwise lethal infections in mice. We demonstrate that acts directly on bacteria by targeting their membrane, while also modulating host immune response and dampening unwanted inflammation. Venom-derived molecules such as ones described here represent an exciting new source antibiotics.
