Hadejia reservoir is a floodplain complex in north eastern Nigeria. This area has long been noted for its importance in fish production. It is also important to both year round native birds and European water birds that travel over the Sahara desert to this wetland to spend their winters. Quantitatiive and qualitative profile of bacteria in the reservoir was carried out. Quantitative analysis of bacteria in the water revealed that the water contained total heterotrophic count (THC) of 3.1 x 103 CFU/ml to 3.5 x 106 cfu/ml and total coliform count (TCC) ranging from 1.4 x 102 to 1.4 x 103 CFU/ml. Bacteria load in the fish intestines were 3.5 x 103 CFU/g and 3.1 x 104 CFU/g for total coliform and total heterotrophic count respectively. Fish gills had less count (2.1 x 102 CFU/g and 3.4 x 102 CFU/g for TCC and THC respectively), than the fish intestines. Bacteria species such as Aeromonas hydrophila, Vibrio cholera, Shigella species were isolated from the water samples. Escherichia coli, Salmonella sp. Shigella sp. were isolated from the fish samples.
