    Bacteriological and Physicochemical Analyses of Borehole and Well Water Sources in Ijebu-Ode, Southwestern Nigeria
    (IOSR Journal of Pharmacy and Biological Sciences, 2013-12-31) Bello, Olorunjuwon O.; Osho, A.; Bankole, S.A.; BELLO, Temitope.K.
    An investigative study was carried out to determine the bacteriological and physicochemical qualities of borehole and well water samples in Ijebu-Ode, Southwestern Nigeria. Ten water samples each of borehole and well water sources were collected within the geographical location. Physicochemical parameters were determined using standard methods. The total bacterial count was determined by pour plate technique and total coliform determined using 3-3-3 regimen. Identifications of isolates were done using standard methods. The colour and turbidity of water samples were within the normal range. Eight genera of bacteria which include Escherichia coli, Klebsiella sp, Salmonella sp, Shigella sp, Enterococcus sp, Proteus sp, Pseudomonas aeruginosa and Staphylococcus aureus were isolated from the water samples. Total bacterial count in borehole and well waters sampled ranged from zero to 2.5 x 102 cfu/ml and zero to 8.1 x 102 cfu/ml, respectively. The total coliform count of the borehole waters analyzed ranged from zero to 16 MPN index of coliform/100 ml while that of well waters ranged from 16 to 1100 MPN index of coliform/100 ml of the water samples. All borehole water samples had zero faecal coliform count while in well water samples, count ranged from zero to 4.1 x 102 cfu/ml. It was concluded that not all borehole waters are safe for consumption and well waters were of poorer bacteriological qualities indicative of health risk to the inhabitants of the geographical location.

    Microbial Qualities of Swimming Pools in Lagos, Nigeria
    (International Journal of Applied Science and Technology, 2012-10-31) BELLO, Olorunjuwon O.; MABEKOJE, Oladele O.; Egberongbe, Haneefat O.; BELLO, Temitope.K.
    Twenty different swimming pools in Lagos, Nigeria, were investigated for their microbial qualities. Water samples from the swimming pools were serially diluted and dilution factors of up to 10-8 were cultured on the appropriate agar media. The pour plate technique was adopted using standard plate count agar for the determination of the total heterotrophic bacterial and fungal counts. Bacterial and fungal isolates were identified using standard methods. Bacterial isolates include Enterococcus faecalis, Clostridium perfringens, Bacillus cereus, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Proteus vulgaris and Staphylococcus epidermidis, while fungal isolates were Penicillium sp, Rhizopus sp, Aspergillus versicolor, Fusarium sp, Trichophyton mentagrophytes, Mucor sp, Candida albicans, Aspergillus niger and Absidia sp. The mean heterotrophic bacterial count ranged from 3.0x106 cfu/ml which occurred in sample R, to 6.6x107 cfu/ml in sample Q while the mean coliform count ranged from a nil count/100 ml to 1.7 x 107 cfu/100 ml (sample S). Fungal counts ranged from a nil count/ml to 2.0x107 cfu/100 ml in sample F. In conclusion, the presence of high levels of coliform and fecal coliform bacteria (E. coli) revelaed that the swimming pools have not met the World Health Organization (WHO) standard for recreational waters. The swimming pools constitute a serious public health hazard, thus necessitating urgent and effective intervention.

    MICROBIOLOGICAL AND PHYSICOCHEMICAL EVALUATIONS OF SOME STREAMS ALONG ILISAN-AGO IWOYE ROAD, OGUN STATE, NIGERIA
    (ASIAN ACADEMIC RESEARCH JOURNAL OF MULTIDISCIPLINARY, 2013-10-31) EGBERONGBE, H.O.; Bello, Olorunjuwon O.; AWODERU, V.A.; BELLO, Temitope.K.
    Microbial and physicochemical analyses were carried out on water samples collected from seven different streams from different communities along Ilisan, Ago-Iwoye Road, Ogun State, Nigeria, using standard procedures. The evaluated streams include Ome, Ogboni, Ogbe, Ona, Orisa, Oruken and Ayanyelu. The physicochemical parameters assayed for include temperature, pH, taste, appearance, odour, presence or absence of particles. Mannitol salt agar medium was used for the isolation of Staphylococcus aureus, while Salmonella- Shigella was used for isolation of Salmonella sp. The coliform test was employed to detect the faecal organisms while the Most Probable Number (MPN) was by the multiple tube fermentation technique. Oruken stream had the highest number of bacterial isolates with total count of 5.73 x 105 cfu/ml while Orisa stream had the lowest bacterial isolates with total count of 0.29 x 105 cfu/ml. The microorganisms isolated include Escherichia coli, Proteus mirabilis, Bacillus firmus, Salmonella typhi and Staphylococcus aureus. Most of the stream waters were unsafe for drinking as they were of low quality thresholds. Thus, the stream waters require further purification to ensure their suitability for human consumption
