“…Mihajilov-Kristev et al . [33], showed that essential oil containing mainly carvacrol (67.0%) and γ-terpinene (15.3%) is effective against Gram-negative strains, including Escherichia coli , with MIC values from 0.025 µL/mL to 0.78 µL/mL according to the broth microdilution method. In our study for basil and rosemary essential oils, we obtained significantly higher MIC values.…”

Abstract:The considerable therapeutical problems of persistent infections caused by multidrug-resistant bacterial strains constitute a continuing need to find effective antimicrobial agents. The aim of this study was to demonstrate the activities of basil (Ocimum basilicum L.) and rosemary (Rosmarinus officinalis L.) essential oils against multidrugresistant clinical strains of Escherichia coli. A detailed analysis was performed of the resistance of the drug to the strains and their sensitivity to the tested oils. The antibacterial activity of the oils was tested against standard strain Escherichia coli ATCC 25922 as well as 60 other clinical strains of Escherichia coli. The clinical strains were obtained from patients with infections of the respiratory tract, abdominal cavity, urinary tract, skin and from hospital equipment. The inhibition of microbial growth by both essential oils, presented as MIC values, were determined by agar dilution. Susceptibility testing to antibiotics was carried out using disc diffusion. The results showed that both tested essential oils are active against all of the clinical strains from Escherichia coli including extended-spectrum β-lactamase positive bacteria, but basil oil possesses a higher ability to inhibit growth. These studies may hasten the application of essential oils in the treatment and prevention of emergent resistant strains in nosocomial infections.

“…The greatest effect ( Table 3 ) on bacterial growth was with the direct application (without dilution) of 100 µL of essential oil extract, which led to 81% inhibition of S. aureus and 73% inhibition of E. coli. Bibliographic references indicate that the minimum inhibitory concentration (MIC) of EOs of Satureja hortensis that absolutely suppressed the visible microbial growth of several bacteria and fungi, including S. aureus and E. coli, was 0.2 µL EOs/mL methanol for the S. aureus strain [ 23 ], which is a lower dose of EOs than that used in this study. In another study on the EOs of Satureja spicigera, the MIC was of 1.5 mg/mL for S. aureus and 6 mg/mL for E. coli [ 24 ].…”

Satureja macrostema is a plant that is located in various regions of Mexico and is used in a traditional way against illness. Essential oils (EOs) were obtained from leaves Satureja macrostema and the chemical composition was evaluated by gas chromatography–mass spectrometry (GC-MS). The antioxidant effect of the oil was assayed by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and by Trolox Equivalent Antioxidant Capacity (TEAC). In vitro antibacterial activity against Escherichia coli and Staphylococcus aureus was determined using a broth microdilution assay and thin layer chromatography–direct bioautography (TLC-DB) to identify active antibacterial compounds. The EOs analysis showed 21 compounds, 99% terpenes, and 96% oxygenated monoterpenes, with trans-piperitone epoxide (46%), cis-piperitone epoxide (22%), and piperitenone oxide (11%) as more abundant compounds. Likewise, S. macrostema EOs showed an antioxidant activity of DPPH = 82%, with 50% free radical scavenging (IC50) = 7 mg/mL and TEAC = 0.005, an antibacterial effect against E. coli of 73% inhibition, and 81% over S. aureus at dose of 100 µL of undiluted crude oil. The TLC-DB assay showed that the most active compounds were derived from piperitone. The comparison with other studies on S. macrostema shows variability in the compounds and their abundances, which can be attributed to climatic factors and the maturity of plants with similar antioxidant and antibacterial activities.

“…After hydrodistillation in the Clevenger-type apparatus, content of essential oils in the plant material was in the range from 0. 10 (14,4) and S. horvatii (thymol -63.37%) (7). Allmost each previous mentioned species also contains high percent of γ-terpinene and pcymene, which are precursors of these phenol compounds (especially S. adamovicii 40.00%) (13).…”
