Determination of Antimicrobial Properties of Myristica fragans (Nutmeg) on Microorganisms Isolated from Veritas University Hostels Bathroom and their Surfaces

The bathroom which is a place for people to clean up themselves is also prone to contamination. The aim of this study was to investigate the antimicrobial properties of nutmeg against isolates from the bathroom using different solvents such as acetone, ethanol and water for the extraction of the nutmeg. In this study, samples from different areas in Veritas University male and female hostel bathrooms were screened for bacterial and fungal contamination and results from the study showed that bacterial genera such as Escherichia coli, Salmonella, Staphylococcus aureus, Bacillus, Pseudomonas, and fungus Aspergillus were found in this public bathroom surfaces. The Cup-plate Agar Diffusion method was used to determine the antibacterial potency of the nutmeg while the Filter paper method was used to determine its antifungal properties. The results proved that nutmeg has great anti-microbial properties thus was capable of inhibiting the growth of these isolates. Results from this study also revealed that when acetone was used as the solvent at 75% concentration, it was the most effective for the antibacterial susceptibility test while ethanoic solvent at the same concentration was the most effective for the antifungal susceptibility testing.
