Le résumé fourni par la source

The prevalence of microorganisms in full scale water supply systems raises concerns about their pathogenicity and effects to public health.Clean tap water is essential for public health safety.The source water quality, the drinking water distribution system, and building water supply systems in buildings, greatly influence the microbial community in tap water.Given the importance of drinking water biosafety, the study of microbial diversity from source water to tap water is essential.This study is aimed at evaluating and determining the microbial quality of the borehole drinking water at St. Thomas Aquinas Parish G.R.A Awka.The water samples were collected from three different tap outlets, using three clean sterile containers, the taps were swabbed externally using a sterile cotton wool dipped in 75% alcohol, after which it was opened and allowed to run for five minutes respectively before the water samples were collected and sent immediately to the Microbiology laboratory in Nnamdi Azikiwe University Awka for analyses.The samples were cultured for both bacteria and fungi, with different agar medium using the pour plate, membrane filtration and fungi microscopy methods respectively.The results showed that the water sample had no bacteria growth after 24 hours of culture a total of seven fungal growth was counted, and three different isolates were identified (Aspergillus sp., Fusarium sp., Penicillium sp.,), in the fungal agar medium after three days of culture The fungal colonies were too few to be counted using the standard method of fungi colony count (TFC=N/VD × 10).
