Item Comparative bacteriological analysis of stored borehole water sources in Oyo town, Oyo State, Nigeria(African Journal of Microbiology Research, 2020-01) Oluwasanmi Anuoluwapo ADEYEMI; Tobiloba Kehinde EFUNWOLE; Afolake Atinuke OLANBIWONINUWater contamination is one of the leading causes of deaths and diseases worldwide, accounting for the deaths of more than 14,000 people daily, majority being children under 5 years old, therefore periodic monitoring of municipal water supplies are necessary. Comparative bacteriological analyses of twenty five samples of stored borehole water from five hostels in a tertiary institution in Oyo, Oyo State, was carried out using standard microbiological methods between March and April, 2018 to determine their bacteriological content. The hostels were: University Female Hostel (UFH), Diocese of Lagos West Hostel (DLW), Joseph Adetiloye Hostel (JAH), Diocese of Lagos Hostel (LAG) and Peter Jasper Akinola Hostel (IBD). A total of thirteen (13) different bacteria genera were isolated and identified as: Aeromonas (17%); Escherichia (4%); Staphylococcus (9%); Pseudomonas (9%); Lactobacillus (13%); Corynebacterium (27%); Micrococcus (6%); Streptococcus (3%); Serratia (4%); Klebsiella (1%); Citrobacter (3%); Shigella (3%); and Salmonella (1%). The total viable count ranged from 5.0×103 cfu/mL (IBD) to 1.23×105 cfu/mL (DLW). Total coliform bacteria counts of the stored water ranged from 0 to 28 MPN/100 mL. The bacteria load and presence of coliforms and pathogenic organisms raised grave concerns as WHO permissible limits for total viable count and coliforms are 100 cfu/mL and 0 MPN/100 mL, respectively. The organisms isolated are of public health significance as ingestion of water contaminated by them could result in gastroenteritis, especially Escherichia that indicates possible fecal contamination.
