Abstract: The antibiotic sensitivity pattern of bacteria isolated from different water source in Akure metropolis was investigated in vitro. Water samples were collected aseptically from well, borehole and stream for microbiological analysis. Escherichia coli, Aerobacter aerogenes and Alcaligene feacalis were isolated from stream water while Proteus vulgaris and Micrococcus luteus were encountered from well water. Two different bacteria were also isolated from borehole water these include, Proteus vulgaris and Bacillus cereus. Oflaxacin was the most sensitive antibiotic because it showed the highest zone of inhibition against Bacillus cereus. In addition, all the bacteria were sensitive to it, but Micrococcus luteus was the least sensitive bacterium to Oflaxacin. Augmentin, Tetracycline, Amoxillin and Contrimoxazole have no effect on Micrococcus luteus. Stream water had the highest coliform count of 25/100 mL and a microbial load of 3.00�104 cfu mL 1. This was followed by well water which gave coliform count of 13/100 mL and a microbial load of 1.62�104 cfu mL 1. Borehole water gave the least coliform count of 5/100 mL and a microbial load of 0.31�104 cfu mL 1.
