“…The essential oils (EOs), a mixture of a large and diverse class of terpenoid and phenolic compounds isolated from aromatic plants, have been of such a great interest during the last decades for exhibiting broad biological properties; among them, antibacterial, antiparasitic, antifungal, and antiviral properties have been reported [17,18]. In addition, previous studies have also demonstrated the potential activity of EOs as antineoplastic, anti-inflammatory, allelopathic, antioxidant, insecticidal, and repellent, making them excellent candidates for new natural drugs discovery [19][20][21]. Thus, in this study, E. coli and S. epidermidis were both selected for studying the antimicrobial, antibiofilm and anti-QS activities of seventeen essential oils derived from Lippia origanoides, Thymus vulgaris, Lippia alba, Cymbopogon martini, Cymbopogon flexuosus, Rosmarinus officinales, Salvia officinales, Swinglea glutinosa, Tagetes lucida, Satureja viminea, Cananga odorata, Citrus sinensis, and Elettaria cardamomum.…”

Both the ability of bacteria to form biofilms and communicate through quorum sensing allows them to develop different survival or virulence traits that lead to increased bacterial resistance against conventional antibiotic therapy. Here, seventeen essential oils (EOs) were investigated for the antimicrobial, antibiofilm, and anti-quorum sensing activities on Escherichia. coli O157:H7, Escherichia coli O33, and Staphylococcus epidermidis ATCC 12228. All essential oils were isolated from plant material by using hydrodistillation and analyzed by GC-MS. The antimicrobial activity was performed by using the microdilution technique. Subinhibitory concentrations of each EO were assayed for biofilm inhibition in both bacterial strains. Quantification of violacein in Chromobacterium violaceum CV026 was performed for the anti-quorum sensing activity. The cytotoxicity activity of the EOs was evaluated on Vero cell line by using MTT method. Thymol-carvacrol-chemotype (I and II) oils from Lippia origanoides and Thymus vulgaris oil exhibited the higher antimicrobial activity with MIC values of 0.37–0.75 mg/mL. In addition, these EOs strongly inhibited the biofilm formation and violacein (QS) production in a concentration-dependent manner, highlighting thymol-carvacrol-chemotype (II) oil as the best candidate for further studies in antibiotic design and development against bacterial resistance.

“…If the value of the inhibition zone of the EO/ AB combination is significantly higher (P <0.05) than the sum of the individual values, this is considered to be a synergistic effect, but if they are equal (P ≥0.05), then this is considered an additive effect. The antagonistic effect occurs when the values of the inhibition zones of both treatments separately EO/AB are significantly greater than the value of their combination (Boudjedjou et al, 2018(Boudjedjou et al, , 2019.…”

“…The occurrence of synergism is thought to be the key to the bioactivity of EOs (Boonyanugomol et al, 2017;Chouhan et al, 2017). Therefore, the association between EOs and ABs has emerged as a novel approach in controlling multidrug-resistant (MDR) strains and modulating the activity of ABs (Boonyanugomol et al 2017;Chouhan et al, 2017;Boudjedjou et al, 2018Boudjedjou et al, , 2019.…”

Antibiotic resistance has been called one of the world’s most pressing public health threats. The combination of essential oils with conventional antibiotics is one of the emerging approaches that could help prevent this problem. In light of this, this study aimed to investigate the impact of combination of Ruta montana essential oil with conventional antibiotics on some pathogenic bacteria. The essential oil isolated by steam-hydrodistillation was first analyzed using GC-MS then tested alone and in combination with five recommended antibiotics against three bacterial strains by the agar disc diffusion and broth micro-dilution methods. Out of forty-nine peaks, thirty-eight components were identified representing 98.17% of the total oil composition. The major components were 2-Undecanone (63.39%), 2-Nonanone (5.65%), 2-Acetoxytetradecane (4.94%), 2-Decanone (4.47%) and 2-Dodecanone (3.35%). While R. montana essential oil showed only weak antibacterial activity compared to the antibiotics tested alone, unexpectedly, the combination of RM essential oil with antibiotics remarkably increased the antibacterial activity of the antibiotics through synergistic effects in up to 70% of cases. These results suggest that combining antibiotics with essential oils, even those with low antibacterial activity, may be effective in overcoming problems caused by increasing bacterial resistance.

“…The dominant constituents identified in the sample are cadina-1(10)4-diene (10.69%) [14], germacrene D (9.79%) [15], octane (9.37%) [14], pelargonaldehyde (9.06%) [16], and 3-Furancarboxaldehyde (6.87%) [17]. Other minor constituents of the oil are myristicin (4.00%) [18], 1,1,4-Trimethylcyclohexan (3.83%), α-terpinene (3.24%) [19], Thiophene,2-[(methylthio) ethynyl] (3.11%) [18], p-Menthan-3-one, cis-p-(2.88%) [14], β-Pinene (2.60%) [15], camphene (2.59%) [18], 2-vinyl-5methylfuran (2.16%) [16], and myrcene (2.10%) [18]. These qualitative and quantitative differences in the chemical composition of essential oils could be attributed to several factors such as geographical location, the climatic effects, harvest season, nature of the soil, age of the plant parts, the state of used plant materials (dried or fresh), the part of the plant used, time of collection, and chemotype [20,21].…”

Objective: The objective of the study was to find out the antibacterial efficacy and identify the main constituents of the essential oil of Atriplex halimus from southwest of Algeria. Methods: The essential oil from the aerial parts of the endemic plant A. halimus (saltbush in English, qataf in Arabic) collected from the region of Sahara southwest of Algeria was isolated by hydrodistillation and analyzed by gas chromatography–mass spectrometry. Antibacterial potency of essential oil from this plant has been tested against Staphylococcus aureus (ATCC 29213), Escherichia coli (ATCC 25922), and Bacillus cereus (ATCC11778) by disk diffusion assay. Results: The essential oil revealed the presence of 14 components, the dominant compounds arecadina-1(10), 4-diene (10.69%), germacrene D (9.79%), octane (9.37%), pelargonaldehyde (9.06%), 3-Furancarboxaldehyde (6.87%), β-pinene (2.6%), camphene (2.59%), and myrcene (2.10%). The essential oil exhibits very effective antimicrobial activity using disk diffusion assay method with minimum inhibitory concentration ranging from 0.82 μl/ml to 2.4525 μl/ml. Conclusions: This result showed that this native plant may be a good candidate for further biological and pharmacological investigations.
