Abstract: Clay and other mineral products have been documented as remedies for numerous human diseases throughout history with a number of success stories. In this study, the antimicrobial activity of the aqueous leachates of five clay samples collected from Keta, Anloga, Half-Assini, Sogakope and Savietula, all in Ghana, were examined. The in vitro antimicrobial activity of the aqueous leachates were tested against nine microbes using agar well diffusion assay. Of the five clay samples, Sogakope clay leachate possessed the highest antimicrobial activity, showing varying zones of inhibitions against all nine test microorganisms. All other leachates exhibited antimicrobial activity against at least one of the test microbes, except for clay leachate from Anloga which was inactive towards all microbes used in this study. pH and conductivity measurements indicated that Sogakope aqueous leachate had the lowest pH of 2.81 and a conductivity of 54.2 µS/cm while aqueous leachates of Anloga, Keta, Half-Assini and Savietula clays had pH values of 10.27, 7.66, 4.88, 8.01 and conductivities of 94.8, 5.86, 2.02, 91.40 µS/cm respectively. Metal analysis revealed that all clay samples have comparable compositions. Clay deposits may potentially provide cost-effective topical antibacterial treatments.
