Antimicrobial Efficiency of Essential Oils from Traditional Medicinal Plants of Asir Region, Saudi Arabia over Drug Resistant Isolates

Abstract: Antimicrobial resistance (AMR) is a recurring global problem, which constantly demands new antimicrobial compounds to challenge the resistance. It is well known that essential oils (EOs) have been known for biological activities including antimicrobial properties. In this study, EOs from seven aromatic plants of Asir region of southwestern Saudi Arabia were tested for their antimicrobial efficacy against four drug resistant pathogenic bacterial isolates (Staphylococcus aureus, Streptococcus pyogenes, Escherich… Show more

“…In the same context, the Table 3, Table 4 and Table 5 show that the MFC results of the studied extracts show high antifungal activity (MFC) against the studied Candida albicans for chloroform and ethyl acetate extracts (21 ± 0.8 and 18 ± 0.6 mm inhibition zone diameter, respectively) and low antifungal activity of methanolic extract (10 ± 0.4 mm inhibition zone diameter) comparing to the standard luconazole antibiotics (20 mm inhibition zone diameter). It agrees with (Helal, 2019) who reported that methanolic extract of P. undulata showing antifungal activity for some fungal strains, for example, C. Albicans 20 mm diameter of inhibition zone and the highest activity toward M. boulardii about 32 mm.…”

“…The best concentrations of EOs that are effective against different microorganisms depend on the type’s of EOs and biopolymers used as shown in Table 2 . According to the study conducted by Helal et al [ 59 ], the results showed that the EOs from Origanum vulgare showed the lowest minimum inhibitory concentration (MIC) of 0.025 mg/mL for Staphylococcus aureus and Streptococcus pyogenes if compared with Mentha cervina (0.05 mg/mL) and Ocimum basilicum (1.6 mg/mL). Besides that, the EOs from O. vulgare , Ocimum basilicum and Mentha cervina were the most active against all isolates, with the inhibitory zone ranges between 17 and 45 mm.…”
