Soil Bottom and Fish (Chrysichthys nigrodigitatus) were collected samples from River Ogun Isheri in order to determine the microbial composition of bacteria and fungi in this river. The intestinal bacterial flora of the fish Chrysichthys nigrodigitatus, was carried out in this study. The bacterial load in polluted soil samples were comparatively higher. Maximum bacterial counts were seen in intestine and gills of the analysed fish. The isolated organism were identified as Staphylococcus sp, Neiserria sp, Proteus vulgaris, Escherichia coli, Enterobacter aerogenes, Micrococcus sp, Aeromonas sp. The findings of this study confirm the moderate occurrence of organisms belonging to Staphylococcus species in the fish. The studies on, bacterial flora and fungi in fish gut and soil water are very much needed for management both in aquaculture and public health, hence, the relevance of this study.
