Antibacterial Effect of Rheum Ribes on Escherichia Coli

Article excerpt

Background: In the current study, the antibacterial effect of Rheum ribes on Escherichia coli was investigated

Methods: After preparation of the extract, the minimum inhibitory concentration and minimal bactericidal concentra- tion (MIC / MBC) were determined. In disc diffusion meth- od, the mean diameter of growth inhibition zones on agar media were determined by preparing discs from different concentrations (400, 600 and 800 ppm). In order to compare the antibacterial effect of Rheum ribes extract with antibiot- ics, antibiogram kits for gentamicin, ampicillin, ciprofloxacin, and cefotaxime was used as a positive control groups.

Results: The results revealed that certain concentrations of the extracts showed significant antibacterial effect on the strains. Extracts with 400, 600 and 800 ppm concentration showed defined growth inhibitory effect and 600 and 800 ppm concentration showed both inhibitory and bacteriocidal effects on the bacteria. …
