Honey, Bee Venom Nanofibers Exhibit Potent Antibacterial Activity

Apitherapeutics and phage-loaded nanofibers as wound dressings with enhanced wound healing and antibacterial activity

Nanomedicine (Lond). 2017 Aug 14

AIM:

Develop green wound dressings which exhibit enhanced wound-healing ability and potent antibacterial effects.

METHODS:

Honey, polyvinyl alcohol, chitosan nanofibers were electrospun and loaded with bee venom, propolis and/or bacteriophage against the multidrug-resistant Pseudomonas aeruginosa and examined for their antibacterial, wound-healing ability and cytotoxicity.

RESULTS:

Among different formulations of nanofibers, honey, polyvinyl alcohol, chitosan-bee venom/bacteriophage exhibited the most potent antibacterial activity against all tested bacterial strains (Gram-positive and -negative strains) and achieved nearly complete killing of multidrug-resistant P. aeruginosa. In vivo testing revealed enhanced wound-healing results and cytotoxicity testing proved improved biocompatibility.

CONCLUSION:

The developed biocompatible nanofibers represent competitive wound-healing dressings with potent antibacterial and wound-healing activity.
