Key Points

  • To investigate the antibacterial effects of fatty acid extracts from Hermetia illucens larvae on colistin-resistant Acinetobacter baumannii.
  • Isolated fatty acid-enriched extracts from Hermetia illucens larvae.
  • Tested antibacterial activity against colistin-resistant Acinetobacter baumannii.
  • Analyzed membrane integrity disruption as a mechanism of action.
  • AWME3 extract showed potent antibacterial activity.
  • Disruption of membrane integrity was likely involved in the antibacterial mechanism.
  • Findings suggest insect-derived compounds could help combat multidrug-resistant pathogens.

Abstract

Fatty acid-enriched extracts from H. illucens larvae, particularly AWME3, exhibited potent antibacterial activity against colistin-resistant A. baumannii, likely through membrane-disruptive mechanisms. These findings highlight the potential of insect-derived bioactive compounds as sustainable alternatives for managing MDR pathogens.
