“…of public health importance owing to their implication in a handful of infections and diseases notable in human populace. This report is similar to the study conducted by Agwu et al and Adekoyeni and Salako who showed that some Gram-positive and Gram-negative bacteria including E. coli and S. aureus are prevalent in borehole water samples in Aba and Ogun state of Nigeria respectively [3,10]. Similar prevalence of bacteria has also been reported by Engwa et al in Enugu state, Nigeria [2].…”

In te rnation a l J o u rn al of W a s te R es ourc e s AbstractThe quality of potable water is affected by several natural and human activities including but not limited to pollution, natural disasters, climate change, urbanization and mining. Poor water quality adversely affects human health, and it is important to periodically be on the lookout for possible water contamination in our environment. This study investigated the metal content and bacteriological profiles of selected borehole water sources in Abakaliki, Nigeria. A total of 25 borehole water samples of 250 ml each were aseptically collected from selected borehole points (designated as Site A-E) in Abakaliki metropolis, Ebonyi State, Nigeria using pre-sterilized plastic containers; and each of the samples was were bacteriologically analyzed on selective culture media for the isolation and identification of bacteria that are of public health importance using standard microbiology identification techniques. The presence of trace metals was chemically determined in the borehole water samples using the atomic absorption spectrophotometer (AAS) [AA-7000]. The highest bacterial count in this study was 2.4 × 10 4 cfu/ml while the least bacteria count was 1.0 × 10 4 cfu/ml. The suspected bacterial organisms isolated and identified from the respective borehole water samples were Escherichia coli, Klebsiella species, Staphylococcus aureus and Pseudomonas aeruginosa. The metal content analysis using AAS showed that some of the borehole water samples contain some trace metals such as zinc (Zn), iron (Fe) and manganese (Mn). Aluminium (Al) and lead (Pb) were not detected in the borehole water samples analyzed in this study; and the trace metals detected were found to be within the accepted limit of trace metals for drinking water as specified by Standard Organization of Nigeria (SON) and World Health Organization (WHO). This study has presumptively reported the presence of some bacterial organisms of public health importance and some trace metals in selected borehole water samples in Abakaliki, Nigeria. The area under study is known for its high deposit of mineral resources especially lead and limestone; however, lead was not detected in the water sample and this shows that there was no infiltration of this metal from the mining site to the water sources in the region. Also, the proliferation of mining sites and their unregulated activities could also be responsible for the presence of some of these metals in the environment at concentrations that are unsafe for human use. Unsafe drinking water portends significant risk to public health over a lifetime of consumption. It is therefore important for the authorities to periodically screen water meant for human use and public consumption for the presence of potential physical, chemical and biologically contaminants that may affect the health of the populace.

“…specie revealed the highest MAR of 90.9% resistance to the antibiotics tested. This corroborates the ndings ofAyandele et al (2019) in Nigeria that reported the multidrug-resistant trait of Corynebacterium species isolated from a close by dam to where the current study was carried out. Furthermore, in Brazil,Conte et al (2021) published the multidrug-resistance of Aeromonas species isolated from aquatic environments.…”

Freshwater habitat is a natural reservoir for antimicrobial resistance (AMR). AMR is known to pose serious human, animal, and environmental public health threats. This study aimed at evaluating the physicochemical and microbiological properties of five selected rivers (Apitipiti 1, Apitipiti 2, Apitipiti 3, Sogidi, and Aba Apa Akinmorin) in Oyo town, Nigeria, as well as the antibiotic resistance pattern of isolated bacterial species, using conventional methods. Most physicochemical parameters were within WHO and NIS permissible limits. Of the rivers, Sogidi had the highest microbial load (6.36 log CFU/mL) while Apititipiti 1 had the lowest (5.76 log CFU/mL). A total of thirty-three (32) bacterial species were isolated and identified as: Aeromonas (9), Bacillus (2), Corynebacterium (13), Lactobacillus (1), Pseudomonas (2), Staphylococcus (4), and Streptococcus (1). Pearson’s correlation matrix indicated that there were significant (p<0.05) interactions among pH, electrical conductivity, temperature, sulphate and chloride salts, BOD and COD. Of all these, 81.8 % were multidrug-resistant, with Corynebacterium kutscheri and Aeromonas spp. isolated from Apitipiti 2 and Aba Apa Akinmorin rivers respectively, exhibiting a relatively high antibiotic resistance of 90.9 %. This study reveals that these rivers maybe unfit for consumption as multidrug-resistant bacteria of public health risk were associated with them.

Water is vital for life, but in contrast, it might serves as the commonest route of transmission for many infectious diseases. This study was carried out to examine the quality of drinking water from two selected surface water within Ogbomoso. Water samples were collected from both water bodies at different points. Most Probable Number (MPN) techniques and pour plate method were used to estimate the bacteriological quality of water samples. The antibiotic sensitivity test was carried out on the isolated organisms, while heavy metals parameters were assessed with standard methods. Water samples were analyzed for faecal sterols. Results of MPN counts (49 to 6 7 1600 MPN per 100ml) and total heterotrophic counts (0.15×10 to 1.36×10 CFU/mL) revealed a high level of microbial pollution. Ten genera of bacteria; Shigella, Corynebacterium, Streptococcus, Pseudomonas, Staphylococcus, Escherichia, Salmonella, Vibrio, Citrobacter and Klebsiella were isolated and they all showed multiple antibiotic resistant (MAR) to all the antibiotics used. The multiple antibiotics resistant (MAR) index ranged from 0.63 to 0.75 and 0.63 to 0.88 for the isolates from Papa-Osiagoro and Oke-Baaki water works respectively. The heavy metals analyzed fell within the limits set by Nigerian Standards for potable waters with exception of Zn which had high concentrations across the sampling points. Water samples showed the presence of high concentrations of feacal sterols. The presence of coliforms and other pathogenic organisms present in these surface water bodies have shown that they are highly contaminated. Thus, the water is not fit for human consumption due to feacal contamination.
