Objective: To evaluate the antibacterial activity of the combination of different honey brands and methanolic fraction of Herba Ocimi Basilici using agar well diffusion assay.
Methods: The antibacterial activity was determined against thirteen pathogenic bacterial clinical isolates including six gram negative (Klebsiella pneumonia, Pseudomonas aeroginosa, Escherichia coli, Salmonella typhi, Salmonella typhimirium, Xanthomonas campestris) and six gram positive strains (Enterococcus faecalis faecalis, Bacillus subtilis, Staphylococcus aureus, Clostridium perfringens type C, Clostridium perfringens type D, Clostridium chauvoei). Agar well diffusion method was used while zones of inhibition were measured with vernier scale.
Results: At higher concentration, all the honey brands showed good to significant activity. The highest activity was observed for Hamdard brand honey (27.60 +/- 0.40) against Enterococcus faecalis.
Conclusion: These results revealed that combinations of plant extracts of Herba Ocimi Basilici with honey can be used for the development of potent and novel antibacterial agents.
