Antibacterial activities of Manuka and Honeydew honey-based membranes against bacteria that cause wound infections in animals

摘要

In this study, membranes composed of honey (Manuka or Honeydew) and pectin were developed, and the ISO 22196 method was used to evaluate their antibacterial activities against multidrug-resistant bacteria (i.e., Staphylococcus pseudointermedius, Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa) that cause wound infection in animals. The results demonstrated that both Manuka and Honeydew honey-based membranes had strong antibacterial activities against the strain of methicillin-resistant S. pseudointermedius tested. Specifically, membranes composed of Manuka honey were effective in inhibiting the growth of Gram-negative bacteria within 3 h, whereas those composed of Honeydew honey needed 24 h to neutralise bacterial growth. The antimicrobial activities of both membranes developed in this study suggest that they can be effectively used as wound dressing in veterinary clinical medicine.
