“…Because of some activities, which are seen regularly such as, the building of toilets on water bodies and the discharge of untreated and improperly treated sewage into water bodies, high levels of temperature [11,12] and high concentrations of heavy metals [13] in water bodies, there is therefore need to check if there are isolates of E. coli from water bodies in Rivers State that have developed mutations.…”

This study characterised Escherichia coli isolated from Creek Road/Bonny Estuary using molecular techniques. One hundred and twenty (120) water samples were investigated for the presence of E. coli in Creek Road/Bonny Estuary. Most Probable Number (MPN) Technique, Eijkman test and molecular techniques were used for the isolation and detection of E. coli. The analysis was carried out periodically (morning and evening) and seasonally (end of rainy season (November), the start of rainy season (April) and in the middle of rainy season (July)). All E. coli isolates were screened for resistance genes in the pathotypes of E. coli (EHEC, EPEC, EAEC, ETEC and EIEC), including Sulfhydryl Variable (SHV), CTX-M, Temoniera (TEM) and MCR genes using the Polymerase chain reaction Technique. The results showed that 100% of the water samples were positive for coliforms and all the water samples harboured E. coli. The highest total coliforms count recorded was in the morning of April (48 MPN/100 ml). The distribution of individual genes in the E. coli isolates are: SHV (5.0), CTX-M (5.8), TEM (4.2), MCR (0.0%), stx1 and stx2 (4.2), esV and bfA (1.7), aaiC (4.2), elt (3.3) and invE (2.5). The CTX-M was the most found of all the resistance genes.

“…The BOD is slightly higher in Station C than in Station B and A. The BOD measure only the biodegradable part of the organic waste concentration [31]. The result depicts that station A offers a better support to aquatic life as it does not contain oxygen demanding waste or pollutant as compared to station B and C.…”

“…In addition, these metals affect the organoleptic quality of water as do other metals such as copper and aluminum [31]. The level of the heavy metals across Miniokoro stream might be due to the anthropogenic activities prevalent in this area and the inability of government to control the possible disposal of solid and liquid waste into the stream.…”

Evaluation of physicochemical parameters and heavy metal levels in surface water of the Miniokoro stream, Port Harcourt, Nigeria were investigated to determine its potability and pollution status at various stations along the stream. The physicochemical parameters analyzed in the water samples were: pH, Temperature, Salinity, Electrical conductivity, TDS, DO, BOD, Alkalinity, Chloride, NH4+, NO3-, PO43-, SO42- while heavy metals such as Nickel, lead, Iron, Zinc and Chromium were analyzed using atomic absorption spectrophotometer. The results from the research showed an average concentration level of the physicochemical parameters such as pH (5.79-7.01), EC (136.43 - 960.67µS/cm), TDS (90.17 - 1517.67) and the spatial distribution of heavy metals: zinc (0.07 - 1.09mg/l), chromium (0.03 - 0.09mg/l), nickel (0.07 - 0.08mg/l) and iron (12.29 - 39.95mg/l). Water samples from various stations depicts the varying level of pollution along the stream when compared with national and international permissible limit. Thus, it suggests that the government should develop and implement an effective waste management plans due to environmental and other anthropogenic impacts on the stream.
