Effect of Moringa Oleifera Seed Extracts on Escherichia Coli

This work is to determine the effect of wonder plant (Moringa oleifera) seed extracts on Escherichia coli. E. coli was isolated, characterized and identified. The moringa seed extract was extracted and characterized, concentration was prepared, preparation of sensitivity disc with the extract, determination of minimum inhibitory concentration and minimum bacterial concentration of extract were done while antibiotics susceptibility test served as the control. The results show that ethanol/extract was highly effective followed by hot water/extract while cold water/extract was the least as the P>0.5. The extracts show promise as a natural antibacterial agent that could be used to combat microorganisms responsible for waterborne illnesses.
