Abstract:
Four different concentrations (10%, 30%, 50% and 100%) of green tea, honey and
black cumin oil were used as antibacterial agents against four multi-drug resistant
pathogenic strains.Strains were obtained from Asidairy hospital, Sakaka city,
Saudia Arabia. These strains include: Enterobacter cloacae, Serratia marcescens,
Escherichia coli and Acinetobacter baumannii. Fixed volumes (1 ml) of the green
tea, honey and black cumin oil poured into wells made in Mueller Hinton agar
previously inoculated with a single bacterium. Zones of inhibition were measured
after 48h incubation for each bacterium. Results indicated that E.coli was the only
strain found to be sensitive to green tea (8-13mm).The four strains were sensitive
or extremely sensitive to honey at concentrations 50% and 100 % and sensitive or
extremely sensitive to black cumin oil at concentrations 30%, 50% and 100%.
