In-Vitro Antimicrobial Activity of Herbal Extracts From Tabuk Region (Kingdom of Saudi Arabia) Against Nosomial Pathogens: A Preliminary Study

Abstract

Aim: The study aims to investigate the antimicrobial activity of herbal extracts from Tabuk region against nosocomial pathogens. Material and Methods:The plants included in this study were collected according to United States Department of Agriculture (USDA). The plants were grinded into fine powder using electric grinder, and the powder was transferred into air tight containers. Extracts of this powder was prepared in form of stock solution that was further used for preparing solutions of different concentrations. Antibacterial tests including minimum inhibitory concentration and maximum bactericidal concentration, broth dilution method, and well-diffusion method were performed. Results:The current study has determined the herbs that possess antimicrobial activity against the most common nosocomial pathogens. The sample extracts including Achinella fragrantissima, Artemisia judaica, Caralluma quadrangular, Cleome droserifera, Rhyza stricta, Moringa, and Ochradenus baccatus were tested for organisms including; Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Candida albicans. The results have depicted positive anti-microbial activity of herbal shrubs. Conclusion:The results have demonstrated positive and promising anti-microbial activities against the nosocomial pathogens.

Floristic Diversity of Jabal Al-Ward, Southwest Tabuk Region, Kingdom of Saudi Arabia

“…Sch.Bip., Artemisia judaica L., Ochradenus baccatus Delile and Rhazya stricta Decne. Were mentioned to have potent anti-microbial activity against nosocomial pathogens [19]. Al-Mutairi et al [13] and Moawed [14] reported that the dominant plant families were: Asteraceae, Brassicaceae, Chenopodiaceae, Fabaceae, Lamiaceae, Poaceae, Resedaceae, and Zygophyllaceae.…”

“…Despite the previous trials to describe the floristic composition of the Tabuk region [9,[11][12][13][14][15][16][17]19,20], Jabal Al-Ward has remained unsatisfactorily studied. Therefore, the present study contributed to investigating and evaluating the floristic composition, phytogeographical distribution, and plant diversity of the wild plant taxa growing in the Jabal Al-Ward region, southwest Tabuk, Saudi Arabia, for the first time.…”
