Progress on antimicrobial peptides against drug-resistant bacterial infection

Drug-resistant bacteria from long term use of antibiotics have been threatened human health. The antibiotics now available cannot meet the needs for clinical treatment of drug-resistant bacteria, therefore, it has been a great challenge to find solutions to the problem. This article summarizes the resistance mechanisms of drug-resistant bacteria and reviews the development of a new broad-spectrum antibacterial agent named antimicrobial peptides(AMPs).
