Objective: To produce natural, non-toxic biologically synthesized silver nanoparticles (Ag NPs) with antimicrobial activity from plant source, Swietenia mahagoni as a remedy for multi-resistant drug microbes.

Methods: The antimicrobial activity of these Ag NPs from Swietenia mahagoni was tested against three bacterial species, E.coli, S. aureus, P. aeruginosa and a fungal species, C. albicans.

Results: The experimental results exhibited satisfactory inhibitions against all tested microorganisms when used at different concentrations viz., 1mM, 3 mM and 5 mM; 3 mM (20 mg/500 μl distilled water) offered the highest sensitivity for E.coli and P. aeruginosa.

Conclusion: Green-synthesized antibacterial agent from Swietenia mahagoni showed good antibacterial and antifungal activity.
