Abstract: Microbes including Escherichia coli, Staphylococcus aureus, Klebsiella spp and Salmonella spp were isolated from the abattoir water and were identified by carrying out Gram�s reaction and some biochemical tests. The seed powder was able to clear the abattoir waste water more compared with the leaf and bark indicating that the seed has high coagulation activity and as such can be used to replace chemical coagulants such as Alum (Potassium aluminium sulphate). The bacterial count of the abattoir waste water treated with the bark showed more decrease in bacterial count when compared with that of the leaf and seed. The antibacterial effect of extracts of the seed, bark and leaf of Moringa oleifera was determined in vitro by the Kirby Bauer method and were used on microorganisms such as Escherichia coli, Klebsiella spp and Salmonella spp. The bark was found to be more effective with a zone of inhibition of 20mm. Phytochemical analysis of the extracts showed that the leaf and seed extracts contained reducing sugars and tannins while the leaf, seed and bark extracts contained anthraquinones.ÂÂ
