Abstract

Presence of Escherichia coli from water supplied by water tanker suppliers in Enugu City was determined. Out of eight different water tanker supplies examined which were designated alphabetically as A, B, C, D, E, F, and H. Escherichia coli was isolated from four tanker suppliers. The membrane filtration technique was used and the presumptive test showed other bacteria such as Klebsiella spp and Bacillus spp were seen growing in the MacConkery agar. The pink colonies on MacConkey plates and metallic blue sheen colour on EMB agar were isolated and subcultured in fresh agar plates incubated at 370c for 24-hrs. The pure cultures were then identified using biochemical tests.
