Evaluation of Physiological Effects Induced by Manuka Honey Upon Staphylococcus aureus and Escherichia coli

Abstract: Several studies have explored the antimicrobial properties of manuka honey (MkH). However, the data available regarding antibacterial action mechanisms are scarcer. The aim of this study was to scrutinize and characterize primary effects of manuka honey (MkH) upon the physiological status of Staphylococcus aureus and Escherichia coli (as Gram-positive and Gram-negative bacteria models, respectively), using flow cytometry (FC) to reveal its antibacterial action mechanisms. Effects of MkH on membrane potential, … Show more

“…The results obtained in this study reveal that treatment time and honey concentration are key factors regarding the induction of membrane injury in S. aureus and E. coli. Moreover, these results revealed that the distinct honey samples act differently between gram positive and gram negative bacteria, a fact which was already described in some previous studies with MkH [15,16,28,29]. While the effect of the different honey samples on S. aureus membrane integrity was limited, in the case of E. coli, the results obtained confirmed more meaningful effects.…”
