Antimicrobial Activity Of Moringa Oleifera Leaves On Staphylococcus Aureus And Escherichia Coli Isolates
ABSTRACT
Moringa oleifera is a fast growing, drought resistant tree of the family Moringaceae, native to tropical and subtropical countries. The plant leaves are very good nutrient supplement for malnutrition and used as antibiotics. This study was aimed at evaluating the antimicrobial activity of Moringa oleifera leaves extracts against Staphylococcus aureus and Escherichia coli from stool sample. The antimicrobial screening of ethanolic extracts of Moringa oleifera leaves were done against Staphylococcus aureus and Escherichia coli. The ethanolic extracts of Moringa showed a diameter zone of inhibition of 23mm against Staphylococcus aureus at 200mg/ml and a diameter zone of inhibition of 22mm against Escherichia coli at 200mg/ml. it was observed that the two micro-organisms were sensitive to ethanolic extract of moringa at 200mg/ml respectively. Agar well diffusion method was used to access the antibacterial effect of the extract on both gram negative and gram positive microorganisms. The Minimum inhibitory concentrations and minimum bactericidal concentrations of moringa against Staphylococcus aureus were 25mg/ml and 50mg/ml respectively and Escherichia coli 6.25mg/ml and 12.5mg/ml respectively. The phytochemical screening shows the presence of bioactive supplements such as tannins, flavonoids, saponins and alkaloids.
