Reduced Bacterial Counts from a Sewage Treatment Plant but Increased Counts and Antibiotic Resistance in the Recipient Stream in Accra, Ghana—A Cross-Sectional Study

Abstract: Wastewater treatment plants receive sewage containing high concentrations of bacteria and antibiotics. We assessed bacterial counts and their antibiotic resistance patterns in water from (a) influents and effluents of the Legon sewage treatment plant (STP) in Accra, Ghana and (b) upstream, outfall, and downstream in the recipient Onyasia stream. We conducted a cross-sectional study of quality-controlled water testing (January–June 2018). In STP effluents, mean bacterial counts (colony-forming units/100 mL) had… Show more

“…A review of antibiotic resistance in Ghana (40% in Accra) with data mainly from human isolates (85%) reported a similar high resistance (over 50%) in E. coli isolates to trimethoprim-sulphamethoxazole, amoxicillin-clavulanate and cefuroxime with relatively lower resistance to gentamicin and ciprofloxacin [19]. A recent study also showed that E. coli and P. aeruginosa isolates from a waste treatment plant and a receiving stream in Accra had higher resistance to amoxicillin-clavulanate, cefuroxime and aztreonam [29]. It is therefore possible that the results seen in drinking water sources may be due to contamination from untreated human and animal waste discharged into the environment.…”

“…Accra, the capital of Ghana, now has three municipal STPs in operation: Legon, Mudor, and Adjen Kotoku. Currently, less than a quarter of the STPs are fully operational [ 14 ]. Built in 2012, the Legon STP has the capacity to process 9000 m 3 of sewage daily [ 17 ].…”

“…In 2012, the Legon STP was built as part of the Accra sewage improvement project with the aim of providing an improved sewage and sanitation system for disposing of wastewater in Accra [ 12 ]. The effluents from the plant are discharged into the Onyasia stream [ 14 ], which serves as a source of irrigation for some vegetable farms, emphasising the importance of good performance.…”
