Antimicrobial activity of commiphora myrrha against some bacteria and candida albicans isolated from gazelles at king khalid wildlife research centre

摘要

Ethanolic and ether extracts of Commiphora myrrha were evaluated for their antimicrobial activity against two Gram negative organisms (.Escherichia coli and Pseudomonas aeruginosa), two Gram positive organisms (Bacillus subtilis and Staphylococcus albus) and fungi represented by Candida albicans isolated from gazelles held at King Khalid Wildlife Research Centre, Thumamah. The method used in evaluation of the antimicrobial activity was the two-layer agar diffusion method. The ethanolic extract of C. myrrha exhibited antimicrobial activity against the Gram negative organisms investigated together with S. albus. On the other hand, the ether extract showed antimicrobial activity against Gram positive organisms investigated and against Candida albicans, with the antifungal activity being greater. The minimum inhibitory concentration of the ethanolic extract against P. aeruginosa and E. coli was found to be 20 and 40 mg mL~(-1), respectively. While the minimum inhibitory concentration of the ether extract against both S. albus and C. albicans was found to be 10 and 40 mg mL~(-1) for B. subtilis, respectively.
