Abstract

The research work was investigated to compare the antimicrobial effect of Moringa oliefera leaf, bark and seed on pathogenic bacteria. Extracts were prepared in aqueous and organic solvents i.e. ethanol, ethyl acetate, methanol and chloroform. Ethanol and ethyl acetate extract of the leaf of M. oleifera were more effective while chloroform showed no zone of inhibition with all bacterial strains except B. subtilis. Leaf extract was selected for further study. With antibiotics, maximum growth inhibition was observed in V. cholerae (98.8%) in first dilution. MIC values demonstrate that in bacterial strains the most sensitive strain with antibiotic was B. cereus (5 mg/ml) and with leaf extract most sensitive strain was B. subtilis (16 mg/ml) however with antibiotics less sensitive strains were S. typhi (18 mg/ml) and with leaf extract less sensitive strain was S. typhi (28 mg/ml).
