Eradication of MRSA biofilm-associated implant infections by low-immunogenic sustained-release lysostaphin fused to thermosensitive polypeptides

Reports engineering of a thermosensitive lysostaphin–polypeptide fusion that forms a sustained-release depot and clears MRSA biofilm implant infections in animal models.

Key Takeaways
  • Please note there may be errors present which affect the content, and all legal disclaimers apply
  • We rationally engineered a chimeric Lst-ELP fusion protein that preserves potent lytic activity
  • Thermosensitivity of Lst-ELP enables in situ formation of a sustained-release depot upon subcutaneous injection
