Aquatic and methanolic extracts of Myrtus communis had antibacterial effect on P. gingivalis, A. actinomycetemcomitans and P. intermediate. - GreenMedInfo Summary

Background and Objectives: Anaerobic Gram negative bacteria are the main cause of periodontal destruction. It has been shown thathave anti-bacterial activity on Gram positive and Gram negative bacteria. The aim of this study was to determine the antibacterial effect of aquatic and methanolic extract ofon some of the oral Gram-negative bacteria.

Materials and Methods: The antibacterial effect of aquatic and methanolic extracts ofwas determined using disk diffusion method at different concentrations from 10 to 500 mg/ml. The diameter of inhibition zones were determined. The MIC was defined using the standard broth macrodilution method. The results of the study were reported descriptively.

Results: The aquatic extract offrom 20 to 500 mg/ml had antibacterial effect onandThe methanolic extract from 10 to 500 mg/ml had antibacterial effect onand. The MIC was achieved at 10 mg/ml, 10 mg/ml and 10 mg/ml for aquatic and methanolic extracts ofonand, respectively.

Conclusion: Aquatic and methanolic extracts ofhad antibacterial effect onand. Most concentrations of aqueous extract were effective on bacteria, so, providing an alcoholic extract, that is a time consuming and costly method, does not seem necessary.
