Antibacterial Activity of Senegalia greggii Seed Ethanolic Extracts using Agar Well Diffusion Assay

Abstract

Senegalia greggii (Acacia greggii) has been used for therapeutically. These medicinal plants contain secondary metabolites, such as phenols, that may have antimicrobial properties. Studies have reported antimicrobial activity of plant species within the Senegalia genera. The purpose of the present study was to investigate the antibacterial activity of ethanolic extract from seeds of S. gregii against S. aureus, E. coli,and K. pneumoniae because these pathogenes are mosst common pathogens that common in human andknown to resisitnat to antibiotics.
The agar well diffusion assay was performed to evaluate antibacterial activity of the S. gregii seed ethanol extracts in different doses.The next bacteria, staphylococcus aureus, Escherichia coli ,and Klebsiella pneumonia. After tretement for 18 h at 37o C the highest inhbition growth bacterial zone was for E.Coli and the lowest for S. aureus. The concluded that S. gregii seed extract has antibacterial activity and useful as antibacterial agents as antibiotic for multi-resistant microorganisms.
