Botanical Study and in vitro Antibacterial Activity of Bersama abyssinica Fresen. (Melianthaceae) on Multi-Resistant Staphylococcus aureus Strains

Objective The objective of this study was to find new natural substances (bioactive) having antibacterial activity on multi-resistant strains of Staphylococcus aureus. Methods and Results The methods of dissemination swab on Muller-Hinton agar and double dilution were used to evaluate the antibacterial activity of aqueous total extract of the stem bark of Bersama abyssinica. All multi-resistant strains of Staphylococcus aureus and the reference strain (ATCC 25923) were sensitive to aqueous total extract (ATE) of the stem bark of B. abyssinica. Conclusion and Application ATE had a bactericidal effect on different strains tested. MBC ranged from 1.5630.0 to 0.0980.0 mg/ml. This result justifies the traditional use of the stem bark of Bersama in treating skin diseases. We have hope on the development of this new substances that can fight the multi-resitantes strains of Staphylococcus aureus at least with the crude extract of the plant.
