ABSTRACT

  Honey has since been found to possess antibacterial property and is therefore employed for wound and gastro-intestinal disease therapy. This study evaluates the antibacterial spectrum and efficacy of honey and compared with tetracycline.  Different concentrations (50, 75 and 100.0 %) of honey were studied in-vitro using Staphylococcus aureus, Klebsiella spp, Escherichia coli and Citrobacter spp. The data obtained showed the inhibitory action of honey with clear zones of inhibition. The result obtained shows that Klebsiella spp is most susceptible to honey and the Citrobacter spp less susceptible at 100% concentration, while tetracycline (2.5 mg/ml) was found to be less potent than 100% concentration of honey against Klebsiella spp and Citrobacter spp. 

The active components of leaves of Mangifera indica were extracted using dimethyl sulfoxide (DMSO) and were tested against Staphylococcus aureus, Escherichia coli, Klebsiella spp and Citrobacter spp using the agar well diffusion method. The extracts inhibited the growth of the test bacteria, having the highest zone of inhibition against Escherichia coli (20 mm) at 100% concentration and the lowest zone of inhibition against Staphylococcus aureus (10.0 mm). The activities of the plant extracts on the inhibited pathogens reduced upon dilution of the extract into 75% and 50% concentration.  

The antibacterial action of honey and mango leave extract showed that there is basis for the traditional use of plant and plants product as a local health remedy and the exploration of their active component for the development of newer antimicrobial agents.
