The causative agents of common bacterial infections that are thought to cause water-borne diseases, namely, Escherichia coli, Enterococcus faecalis, and Bacillus cereus were chosen for the study. The paper-disc diffusion method was used with treatments arranged in a completely randomized design and replicated four times. The M. oleifera extracts showed more inhibitory effect than those of M. ovolifolia. The conventional antibiotic Ampicilin generally showed higher inhibitory effect than the extracts of both M. oleifera and M. ovalifolia. The inhibitory effect varied depending on the solvent used. The n-hexane extracts of both seeds and bark of M. ovalifolia and M. oleifera had almost the same inhibition activities (6 ¡À 1 mm mean inhibition zones) on B. cereus, E. coli %K Antibacterial Activity %K < %K i> %K Escherichia coli< %K /i> %K N-Hexane %K Inhibition %K Methanol %K < %K i> %K Moringa oleifera< %K /i> %K < %K i> %K Moringa ovalifolia< %K /i> %K < %K i> %K Bacillus cereus< %K /i> %K < %K i> %K Enterococcus faecalis< %K /i> %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=66257
