The antibacterial effect of different honey types on four different bacteria was assessed by the agar well diffusion method on duplicate samples and the mean ± SD are presented.
Symbol (-) indicates insufficient samples (n=1 or 0).
Symbol () denotes statistically significance (p< 0.05; enzyme treatment versus no treatment).
