ABSTRACT
The presence of Enterococcus in water is a major indicator of fecal contamination which may come from humans or animals and poses a health risk to humans who come in contact with the water. Swimming pool water samples were collected from 20 different locations in Benin City. The data collected from the swimming pools included number of swimmers per week, how often water is treated and the chemicals used in water treatment and the antimicrobial resistance. The distribution of Enterococcus occurrence based cultural and biochemical characterization were Sapele Road (0%), Ugbowo (66.7%), Government Residential Area (G.R.A.) (14.3%), Airport Road (75%), Ugbor (0%), and Oluku (0%). The highest prevalence occurred in Airport Road while the least was observed in Sapele Road, Ugbor and Oluku swimming pools. The occurrence of Enterococcus species based on treatment reagent(s) used in treatment showed that there was no occurrence observed at swimming pools using chlorine, sodium ash and alum; chlorine, algaecide and alum; and also chlorine and trichloroisocyanuric acid. In this study, the highest antimicrobial resistance was demonstrated to penicillin G with a resistance rate of 100% while the least resistance was observed in tetracyclines and vancomycin with both having a resistance rate of 16.7%. The multiple antibiotics resistance profile of the Enterococcus species in this study ranged from 0.7 – 0.1. All except one of the isolates were resistant to at least two antibiotics and demonstrated an MAR index ≥ 0.3.
