Assessment of the Coliform Bacterial Load of Some Drinking Water Sources in Dutse Metropolis of Jigawa State Nigeria

Abstract

Drinking water samples from 5 sachet water companies, 3 boreholes and 2 taps, collected from different locations of Dutse Metropolis of Jigawa State, Nigeria were analysed for coliform bacterial counts using the Membrane Filtration Technique. All the samples contained some amounts of total coliforms, but mostly within permissible levels. Thirty three percent (33%) of the samples from borehole, 60% from sachet water and 100% from the taps contained faecal coliforms, which indicates contamination. Cultures of the faecal coliforms obtained were morphologically identified using the gram-staining procedure and some series of biochemical tests were carried out in order to identify the organisms. The identified organisms were Escherichia coli (E. coli), Klebsiella sp. and Citrobacter sp. Presence of coliforms above the regulatory set standards indicates contamination and un-safeness of the water for drinking. Presence of organisms such as E. coli, Klebsiella sp. and Citrobacter sp. necessitates improvement in monitoring and water hygiene practices to improve the quality of drinking water in the study area.

Pattern of E. histolytica infection and its correlates among patients in a general practice clinic: A four-year retrospective evaluation

“…Other countries with higher prevalence were 20.0% in Saudi Arabia [ 4] , 17.1% in Yemen [15] , 25.9% in Tajikistan [16] , and 18% in Tanzania [17] . In Nigeria several studies have reported prevalence ranging from as low as 0.1% to values as high as 67.6% [11,12,18,19] . The difference between most of these studies and ours is the fact that most of them were based on a population subset, and some included clinical manifestation unlike ours that reviewed the parasitology records of an undifferentiated hospital population.…”
