Random peptide mixtures inhibit and eradicate methicillin-resistant Staphylococcus aureus biofilms

Abstract

Methicillin-resistant Staphylococcus aureus (MRSA) is a biofilm-forming pathogen that can cause serious health complications in humans, ranging from minor to life-threatening infections. The challenge of successfully combating biofilms requires the discovery of compounds with a novel mode of action. We have recently developed sequence-random hydrophobic-cationic peptides that display a broad antibacterial activity. In the current study we show that our novel compounds are capable of controlling and managing MRSA biofilms and might be used as lead biofilm inhibitor candidates for further studies.
