Heat maps of relative optical density at 24 h for selected manuka honeys and multifloral honey.
Values indicate the relative optical density of wells containing honey compared to the positive control, expressed as a percentage.
Table 5.
Antibacterial activity of multifloral honey amended with concentrations of MGO ranging from 50 to 1000 mg/kg.

Heat maps of checkerboards showing multifloral honey in combination with MGO.
Fig 3.
Time kill curves of thee manuka honeys with varying MGO content, a multifloral honey and artificial honey against S. aureus ATCC 29213 and E. coli ATCC 25922.
MGO content was 1022, 326 and 75 mg/kg for honeys MN03, MN05 and MN14, respectively. For both organisms, viable counts for all honey treatments differed significantly from the untreated controls at each time point.
