“…A wide range of phytochemicals has been reported from E. globulus previously (Gouveia et al, 2012). In this study, eucalyptol and 1R-α-Pinene were found to be major components of E. globulus which is consistent with previous studies as well which also agrees that antimicrobial activity of E. globulus can be due to α-pinene and eucalyptol(1,8-cineole) components present in the oil (Mekonnen et al, 2016;Park et al, 2016). Conclusions: It is concluded that essential oils of C. zeylanicum and E. globulus have diverse phyto-constituents and profound in vitro activity against Salmonella enteritidis and Salmonella gallinarum of poultry origin.…”

Antibiotic resistant Salmonella is a major threat to poultry industry and public health. Medicinal plants are an effective alternative of antibiotics for the control and treatment of multiple drug resistant Salmonella. The objective of this study was to evaluate the in-vitro activity of essential oils of some medicinal plants against multiple drug resistant Salmonella of poultry origin and to determine their active ingredients. Essential oils of Cuminum cyminum, Cinnamomum zeylanicum, Eucalyptus globulus, Allium sativum and Nigella sativa were prepared by steam distillation and their active ingredients were determined by Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Activity of oils against Salmonella enteritidis (n=05) and Salmonella gallinarum (n=05) was determined by well diffusion assay. Broth microdilution assay was employed to determine the minimum inhibitory concentrations of oils. Well diffusion assay revealed that C. zeylanicum and E. globulus had better activity against salmonellae (26±7.6 mm and 16±6.8 mm, respectively) as compared to C. cyminum, A. sativum and N. sativa (8±5.9, 10±6.1, 8±4.7 mm, respectively). Minimum inhibitory concentrations of C. zeylanicum and E. globulus against Salmonella were 64.1±32.1 and 68.9±32.9 µg/mL, respectively. The GC-MS analysis revealed presence of diverse phytochemicals in all essential oils. Major antimicrobial phyto-constituents of essential oils of E. globulus and C. zeylanicum were eucalyptol (82.85%) and 1R-α-Pinene (13.781%), and cinnamaldehyde (64.14%) and eugenol (8.9%), respectively. It is concluded that essential oils of C. zeylanicum and E. globulus have excellent in vitro anti-Salmonella activity. It is insinuated that these extracts may be commercialized as an alternative of antibiotics for the control of Salmonellae in poultry after detailed in vivo evaluations.

“…Antimicrobials have been used for a long time to treat different bacterial infections, but the frequent use of these antimicrobials has resulted in growing antimicrobial resistance. Meanwhile, the essential oils have been shown strong antimicrobial activity against these pathogenic bacteria [ 20 21 ]. Therefore, the current study was conducted to determine the efficacy of EOL against pet turtle-borne bacteria.…”

Pet turtles are well-known to harbor an array of bacterial pathogens which can cause zoonotic infections in humans as well as opportunistic infections in the turtles itself. Essential oils are the natural plant extracts which have been traditionally used for disease treatment. In the present study, the essential oil of lavender (EOL) was examined for its antibacterial activity against thirty-eight strains of turtle-borne pathogenic bacteria belonging to seven species; Aeromonas hydrophila, A. caviae, A. dhakensis, Citrobacter freundii, Proteus mirabilis, Salmonella enterica and Pseudomonas aeruginosa. Antibacterial activity of EOL was tested by means of disk diffusion, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) tests. In addition, the antimicrobial susceptibility pattern of 11 commonly used antimicrobials was examined and the multiple antibiotic resistance (MAR) index was calculated. The results revealed that EOL was active against all tested turtle-borne pathogenic bacteria except P. aeruginosa. The range of MIC and MBC values of EOL against isolates except P. aeruginosa were recorded as 0.5-1% (V/V) and 0.5-2% (V/V), respectively. The MBC/MIC ratio was detected as <4, revealing that the tested EOL was bactericidal. Besides, most of the isolates were resistant to different antimicrobials in antimicrobial disk diffusion test. MAR index values of the tested strains were ranging from 0.27 to 0.91. The outcomes indicate that EOL has a potential to be used as an antibacterial agent against pathogenic bacteria isolated from pet turtles.

“…Therefore, its main component 1,8-cineneol has been used in products for oral hygiene, such as Listerine Cleanmint (Pfizer), Listerine Freshmint (Pgizer), and Walgreens Fresh Breath Antiseptic Mouth Rinse (Walgreen Co.) [99]. The EO was also active against E. tarda, V. ichthoenteri, V. harveyi, P. damselae, S. iniae, S. parauberis, and L. garviae , considered to be pathogens of fish [100]. Furthermore, it exhibits toxic effects against S. aureus and E. coli [101].…”

Essential Oils as Antimicrobial Agents—Myth or Real Alternative?

Herbs and the essential oils derived from them have been used from the beginning of human history for different purposes. Their beneficial properties have been applied to mask unpleasant odors, attract the attention of other people, add flavor and aroma properties to prepared dishes, perfumes, and cosmetics, etc. Herbs and essential oils (EOs) have also been used in medicine because of their biological properties, such as larvicidal action, analgesic and anti-inflammatory properties, antioxidant, fungicide, and antitumor activities, and many more. Many EOs exhibit antimicrobial properties, which is extremely important in fields of science and industry, such as medicine, agriculture, or cosmetology. Among the 250 EOs which are commercially available, about a dozen possess high antimicrobial potential. According to available papers and patents, EOs seem to be a potential alternative to synthetic compounds, especially because of the resistance that has been increasingly developed by pathogenic microorganisms. In this review we summarize the latest research studies about the most-active EOs that are known and used because of their antimicrobial properties. Finally, it is noteworthy that the antimicrobial activities of EOs are not preeminent for all strains. Further investigations should, thus, focus on targeting EOs and microorganisms.
