Peptide alternative to antibiotics could combat antimicrobial resistance crisis

A University of Alberta research team has designed a promising alternative for treating antimicrobial-resistant infections, a pressing global health issue. In a paper recently published in Cell Biomaterials, the team describes preclinical testing results for its human-derived peptide treatment, D-GK17. The peptide is stable and nontoxic to humans and is synthesized to attack the surfaces of bacterial or fungal cells that create biofilms, a sticky matrix that is often impenetrable to antibiotic treatments.
