Note: The data are given as mean ± standard deviation (SD) of triplicate experiments. The statistical comparison between values from the different types of honey and the bacterial strains was done using post hoc Duncan’s test. The values were found to be significantly different (p < 0.05) when compared between different strains of bacteria and different types of honey. ND = not determined.
