"Novel Nasal Antimicrobial Peptide Wipes Out Staphylococcus aureus"

Researchers have discovered a broad-spectrum antimicrobial peptide called polyene, produced by the commensal bacteria Staphylococcus epidermidis, that can eliminate Staphylococcus aureus in the nasal passages. Polyene is effective against a wide range of bacteria, including antibiotic-resistant strains, and has a short-lived nature, reducing the risk of resistance development. This finding highlights the potential of harnessing the antimicrobial properties of commensal bacteria to combat pathogenic infections.
