Cross-seasonal analysis of bacteriological profile of water sources as a disease risk measure

Water is a natural resource and is essential to sustain life. Poor drinking water quality is the cause of several diseases. The aim of this paper was to investigate bacteriological profile of water sources as a measure of disease risk, aimed at providing useful information towards rural water resources management. Five hundred and twenty bacterial isolates (520) were obtained from waters samples collected during the period of study. Majority of the Isolates (305) representing 58.65% of the total were obtained during the dry season, as against (205) representing 41.35% in the rainy season. There was a statistical differences (P> 0.05) of the microbes isolated seasonally. The highest occurring was Klebsiella spp. (9.83±6.99, P> 0.05) in the dry season and the least Shigella spp. P> 0.05. Furthermore dam water sources was observed to poses a high disease risk among the five water sources investigated, whiles borehole water sources possess a lower diseases risk. An alarming observation was the presences of bacteria of public health importance in the water sources. These included Shigella spp. (dysentery), Salmonella typhi (typhoid fever and acute diarrhoeal infection), Salmonella typhi (typhoid fever), and Vibrio cholerea (cholera). In a nutshell, to reduce the level of bacterial contamination of drinking water sources there should be an incessant education on issues such as: environmental awareness, (cultivation sanitation habits and ensure that their surroundings and water sources are not indiscriminately polluted), causes, modes of transmission and prevention of water and sanitation related diseases.Keywords: E. coli, water, Public health and diseas
