Isolation and characterization of Escherichia coli pathotypes and factors associated with well and boreholes water contamination in Mombasa County

Abstract: IntroductionSafe water for human consumption is important, but there is a limited supply. Mombasa County has water shortages making residences rely on other sources of water including boreholes and wells. Microbiological evaluation of drinking water is important to reduce exposure to water borne enteric diseases. This cross sectional study aimed at determining the frequency and characterization of Escherichia coli (E. coli) pathotypes from water samples collected from wells and boreholes in Mombasa County.Meth… Show more

“…The high load of Enterobacteriaceae with varying frequencies was prominent in the different well waters investigated; this is an indication of the poor microbiology quality of the well waters. The result of this study conforms with the findings of several authors discovering the presence of coliforms such as E. coli, Enterobacter and non-coliforms such as Salmonella Typhi, Proteus mirabilis , in most water sources ( 27 , 28 ) and Adesakin et al ( 29 ) have also investigated the quality of domestic water sources in Samaru community in Zaria, Nigeria. Adequate treatment of water is of necessity as the detection of these enteric bacteria in potable water makes it unsafe and quick attention is needed because these bacteria cause diseases that are chronic in human globally.…”

“…Fermentation tubes with no indication of microbial growth were incubated for an additional 48 hrs. [34]. Once the reaction time was completed, the number of fermentation tubes indicating microbial growth per sample was compared to the standard MPN charts and the number of microbes present was recorded.…”

“…This may explain why the quality of the water sources often correlates well with the prevalence of water-related diseases in the community [35]. Additionally, lack of waste treatments in urban areas, insufficient water treatment facilities, as well as mismanagement of the existing water facilities are among the factors that contribute to the deterioration of Africa's water quality [34,36,37]. In addition, the use of chemical contaminants in the cultivable areas of our cities represents a source of risk of contamination of water from wells, boreholes, etc.…”
