ABSTRACT

Water is a necessity for living, and so there is a need to conduct analysis to check if it is safe or not for consumption. Bacteriological examination of water samples sourced within Ikom L.G.A, Cross River State was carried out to determine the bacterial load in the water samples and to determine the organisms that contaminates it. The samples were rain, stream, well, and pipe-borne water. They were collected within Ikom in sterile containers and transported to the Laboratory. Using the pour plating technique, 1ml of water sample was pipetted in sterile petri dishes of Nutrient agar, MacConkey agar and TCBS agar, and was allowed to solidify, with incubation at 37˚C for 24 hours. Bacteriological analysis was carried out on 16 samples, and by microscopy and biochemical test a total of 60 bacterial isolates was identified. The bacteria count of the analyzed sample ranged from 1.0×108 to 2.9×108 cfu/ml. The different bacteria species isolated and their percentage occurrence includes Bacillus spp (20%), Escherichia coli (11.6%), Enterobacter spp Micrococcus (8.3%), Salmonella spp (8.3%), Corynebacterium spp (8.3%), Enterococcus spp (6.6%), Klebsiella spp (5%), Vibrio cholera (6%), Vibrio Parahaemolyticus (1.6%), Pseudomonas spp (1.6%), Serratia marscens (1.6%), Staphylococcus spp  (1.6%) having a percentage occurrence 20%, 11.6%, 8.3%, 6.6%, 6.6%, 6.6%, 5%, 3.3%, 1.6%, and 1.6% respectively. There is no significant difference observed at P>0.05 in the distribution of isolates from rain samples compared to the others.  Bacillus species and other pathogenic bacteria isolated from all the water samples are possible threats to health. It is very important to note that this research is laying emphasis on high level of hygiene adoption and proper use of our water sources for consumption purposes.
