Invitro Antibacterial Activity of the Prosopis Juliflora Seed Pods on Some Common Pathogens

Introduction: Prosopis juliflora is probably the most widespread species of genus Prosopis and it is a good source of compounds that have been shown to be pharmacologically active. This plant has been used as a traditional treatment for several diseases. Aim: To investigate the in-vitro antibacterial activity of the P. juliflora seed pods from Bushehr, South West of Iran. Materials and Methods: In the present study, the antibacterial activity of P. juliflora seed pods extract was tested against Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli and Pseudomonas aeruginosa. The minimum inhibitory concentration (MIC) of the extract was determined for each test microorganism. Results: P. juliflora seed pods extract exhibited antibacterial activity against all four test organisms. The MIC of the extract was 0.312 mg/ml and 0.078 mg/ml for S. aureus and S. epidermidis, respectively and 1.25 mg/ml for both E. coli and P. aeruginosa. Conclusion: P. juliflora seed pods from Bushehr, South West of Iran could be an appropriate source of antibacterial compounds that makes it a promising candidate for further studies.
