Five local soaps! Duduosun, Zee, Hause Soap, Yoruba Soap and Yoruba Soap were investigated for their antibacteria activities against Staphylococcus aureus, Escherichia coli, Staphylococcus epidermidis, Staphylococcus spp, Bacillus spp and Klebsiella spp. Identification of the bacteria species was by standard microbiological techniques which included Gram staining and biochemical testing/,. Minimum inhibitory and minimum bacteria activities of the soaps were determined by the disc agar diffusion method. Dudu Osun and Zee soap had the highest antibacterial activity (18mm against staphylococcus aureus) (15mm against Streptococcus spp). While Mayor and Yoruba soap exhibited the least zone of inhibition (0mm against Bacillus spp) (0mm against Escherichia coli) significant differences (p-value = Nan) were observed on the different concentrations of soap preparations used in the work. Staphylococcus aureus was very sensitive to most of the antibacterial soaps used while Escherichia coli showed higher resistance to the soaps. The local soaps analyzed have bacteriostatic and bacteriocidal effects on the test pathogens while complete resistance was shown by some of the isolates even at higher concentrations of the soap preparation used. The cloth washing soaps had no antimicrobial effect on the tested pathogens. The use of local soaps is thus recommended in homes, schools, offices and hospitals as a way of minimizing and stopping infections that are hither to spread through the hands.
