Abstract

  Microbiological analyses were carried out on African Black Soaps locally produced in three different settlements of Akure, Ondo state, Nigeria and Industrial Medicated Soaps to ascertain the type of organisms associated with them. It was discovered that the Black Soaps and the Medicated Soaps were bacteriologically sterile while ubiquitous air-borne fungi such as Aspergillus niger (2), Aspergillus fumigatus (1), Candida albicans (3) and Aspergillus flavus (2) were present in the African Black Soap samples and as well as the medicated soaps. Comparative evaluation of the antibacterial and the antifungal efficacy of the African Black Soap and Medi- cated Soaps against selected clinical pathogens such as Staphylococcus aureus, Streptococcus pyogenes and Pseudomonas aeruginosa for bacteria; Mucor racemosus, Articulosporum spp. and Saccharomyces exiguus for fungi were done adopting the standard methods described by Clinical and Laboratory Standards Institute (CLSI, 2014). The Minimum Bactericidal Concentration (MBC) of the African Black Soaps (A.B.S.1, A.B.S.2, and A.B.S.3) and that of the Medicated Soaps (I.M.S.1 and I.M.S.2) was not significantly different (400 μg/ml) at P ≤ 0.05 levels of significance while the standard Minimum Inhibitory Concentration (MIC) of the A.B.S. 1, 2, and 3 for the fungal pathogens was 400 μg/ml compared to 600 μg/ml for I.M.S. 1 and 2 respectively at the same level of significance (P ≤ 0.05). Conversely, the results indicated that the potent antifungal properties of locally made African Black Soaps were averagely marginally acceptable at 400 μg/ml concentration making them potent antifungal agents at a relatively higher concentration compared to that of medicated soap at 600 μg/ml concentrations respectively. The findings also proved the potent antimicrobial efficacy of locally made African Black Soaps over Industrial Medicated Soaps.
