Abstract

This study evaluated the antibacterial efficacy of some disinfectants widely used in Nigeria in the elimination of common bacteria found in bathing water. Four (4) skin disinfectants Ivy, Dettol, Izal, and Septol, were added to sterile distilled water containing Escherichia coli (E. coli), Klebsiella spp. and Bacillus spp. which were isolated from a swimming pool. From a total of 288 samples, results revealed that all the antiseptic performed below par in destroying bacillus except for Ivy (41.67 %) and Dettol (12.50 %), which showed tenuous performance in this regard. Septol showed no significant difference in destroying bacteria with a higher number of CFU/100 mL eliminated irrespective of the contact time (p = 0.258). In contrast, Ivy showed high significant difference with bacteria destruction as contact time progressed (p = 0.011). The logistic regression model developed revealed that an increase in dosage promoted the removal of organisms while longer waiting times were only significant for Septol (p = 0.045) and Ivy (p = 0.002). Nagelkerke R2 model fitted properly for Izal and Septol with values of 0.97 and 0.786. The findings of this study showed stark variance among the treatment capacities of these antiseptics. They provided sufficient knowledge in the selection of the available skin disinfectants in the market that are most likely to destroy bacteria in bathing water. Therefore, the inability of these products to correlate with their intended purpose leaves room for re-assessment by their producers and by relevant monitoring agencies in the country to meet the demands of a rapidly growing number of end-users in dire need for improved bathing water quality.
