ABSTRACT
Specimens of Mormyrus rume, Labeo ogunensis and Oreochromis niloticus collected from Ogun River were examined for bacterial flora from the gills, skin, and buccal cavity of these species. The different bacteria isolated were tested for their sensitivities to different antibiotics. A total of nine (9) bacteria were identified (Staphylococcus aureaus, Proteus mirabilis, Klebsellia pneumonia, Pseudomonas aerogenosa, Escherichia coli, Proteus vulgaris, Enterobacter aerogenes, Serretia marcescens and Salmonella spp) and incidence of the bacteria count of Mormyrus rume was highest in the skin (5.00±0.60, f<0.05) than gills (3.60±0.98, f<0.05) and buccal cavity (1.22±0.76, f<0.05), in Labeo ogunensis bacteria count was highest in skin (5.30±0.70, f<0.05) than gills (4.80±0.80, f<0.05) and buccal cavity (3.70±1.07, f<0.05), in Oreochromis niloticus bacteria count wasalso highest in skin (6.20±0.83, f<0.05) than gills (5.95±0.79, f<0.05) and buccal cavity (4.54±0.78, f<0.05). it was noticed that in all nine (9) bacteria, Gentamicin and Ceforoxime were most sensitive but at different levels, while all bacteria isolated are most resistant to Caftazidime followed by Oflaxacin.
