Antibiotic sensitvity and plasmid profiles of bacteria isolated from water sources in Oproama community in the Niger Delta

The antibiotic sensitivity pattern and plasmid profile of Escherichia coli, Vibrio and Salmonella species isolated from well and river water sources in Oproama Community were investigated. Antibiotic sensitivity profiles of the bacteria (Escherichia coli, Vibrio sp. and Salmonella sp.) isolated from the water showed high sensitivity to oflaxicin, nalidixic acid and nitrofurantoin and high resistance to amoxicillin, augumentin, cotrimazole and tetracycline. Multi antibiotic resistant index (MARI) as high as 0.375 (Escherichia coli: E9; Vibrio spp.: V3, V4, V10; Salmonella spp.: S1, S9), 0.5 (Vibrio spp.: V2; Salmonella spp.: S2, S4) and 0.75 (Salmonella spp.: S7) were recorded after curing the plasmids with sodium deodecyl sulphate (SDS). The plasmid profiles revealed that 60% of the isolates harboured detectable plasmids with sizes up to 23.130 kb.Keywords: Antibiotics, Escherichia coli, Plasmid, Salmonella, Vibri

Enterotoxicigenicity profile of Escherichia coli , Vibrio , and Salmonella species isolated from well and river water sources in Oproama town in the Niger Delta, Nigeria

Well water is the only source of drinking water in Oproama Town in Rivers state, Nigeria. Water from these sources is consumed without treatment, and potentially poses a health risk to the local population. The Enterotoxigenicity profile of Escherichia coli , Vibrio and Salmonella species isolated from well and river water sources in Oproama were investigated using fluid accumulation (FA) ratio. The study revealed that Salmonella isolate (S9) from the river showed doubtful toxicity out of the ten Escherichia coli, ten Vibrio and ten Salmonella isolates. This study revealed a near-absence of enterotoxigenic Escherichia coli, Vibrio and Salmonella organisms from the waters in Oproama. More studies are required to further test the overall safety of these water sources due to the potential risk of consuming untreated water
