A laboratory Evaluation of Antibacterial Activity of Commiphora myrrha Gum Resins from Kingdom of Saudi Arabia 2023

Background: Today therapeutic plants are regarded as an essential part of human life, the study of antimicrobial activities of plants involves the care of the possible practice of these ordinary crops Objective: The main goal of the present work is to assess the antibacterial activity of Commiphora myrrah on pathogenic bacteria. Methods: The experimental study was conducted between April and May 2023. Fresh Commiphora myrrah gums used in my work were collected from Aqiq town, Saudi Arabia. Commiphora myrrah gums were effectively extracted by using cool and hot water for 48 hrs. as traditional uses . Five strains of bacteria were used. Minimum Inhibitory Concentration was determined by using the agar well diffusion method as the method reported by Saadabi et al. (2012). We used three drops of overnight cultured bacteria. Each extract; hot water and cool water was verified in contradiction of the five strains of the organism using the agar diffusion method (Groove and Randall, 1955) and measured the zones of inhibition. Results: In this study resin Commiphora myrrah was selected to estimate their antimicrobial activities against five isolated bacteria (one strain Gram-positive and 4 strains Gram-negative). Our findings similarly exposed that C. myrrah hot extract gives advanced antimicrobial activities on tested isolate strains.Despite, there were similar efficiency of C. myrrah and the used antibiotics on almost all tested microorganisms, sometimes C.myrrah has more efficiency than some antibiotics against some tested bacterial strains.Cool extracts of C.myrrah have less efficiency against all tested strains.
