Antimicrobial activity of eucalyptus essential oil against Pseudomonas in vitro and potential application in refrigerated storage of pork meat

Abstract: Summary The objective of this study was to investigate the influence of eucalyptus essential oil (EO) on the Pseudomonas in vitro and application in the pork meat. Eucalyptus oil showed the greatest antimicrobial activity to Pseudomonas among five EOs (tea tree oil, eucalyptus oil, clove oil, mentha oil and garlic oil) in vitro. Eucalyptus oil treatment caused the increasing of membrane permeability and the modifications of ultrastructure and morphology of Pseudomonas spp. and P. aeruginosa. Treatment of refrigerated pork with eucalyptus oil led to a significant decrease P. spp. count, pH, total volatile basic nitrogen and 2-thiobarbituric acid values, as well as higher sensory scores of custom acceptance than those in control at the end of cold storage. It was conclude that eucalyptus EO is a potential alternative to chemical treatment to control the spoilage and extend the shelf life of refrigerated pork meat.

Antimicrobial Efficacy of Various Essential Oils at Varying Concentrations against Periopathogen Porphyromonas gingivalis .

Abstract: Introduction Porphyromonas gingivalis (P.gingivalis) is a notorious perio-pathogen with the ability to evade host defense mechanism and invade into the periodontal tissues. Many antimicrobial agents have been tested that curb its growth, although these agents tend to produce side effects such as antibiotic resistance and opportunistic infections. Therefore search for naturally occurring anti-microbials with lesser side effects is the need of the hour. Aim The aim of this study was to substantiate the antimicrobial activity of various essential oils; eucalyptus oil, chamomile oil, tea tree oil and turmeric oil against P. gingivalis. Materials and methods Pure cultures of P. gingivalis were grown on selective blood agar. Antimicrobial efficacy of various concentrations of essential oils (0%, 25%, 50% and 100%) was assessed via disc diffusion test. Zone of inhibition were measured around disc after 48 hours in millimeters. Results Zones of inhibition were directly proportional to the concentration of essential oils tested. At 100% concentration all the tested oils possess antimicrobial activity against P.gingivalis with eucalyptus oil being most effective followed by tea tree oil, chamomile oil and turmeric oil. Conclusion All essential oils tested were effective against P.gingivalis. After testing for their clinical safety they could be developed into local agents to prevent and treat periodontitis.

Essential Oils and Their Vapors as Potential Antibacterial Agents against Respiratory Tract Pathogens.

Abstract: Increasing appearance of antibiotic-resistant pathogens, which could be one of the major causes of respiratory tract infections, has again drawn attention to natural substances and alternative treatments. Therefore, the aim of the present study was the antibacterial evaluation of cinnamon bark, clove, thyme, citronella, peppermint, Scots pine, and eucalyptus essential oils (EOs) against respiratory tract pathogens such as methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa with in vitro vapor phase (VP) and tube dilution (TD) techniques. The chemical and percentage compositions of the EOs were determined by GC-FID and GC-MS analysis. Among the EOs, cinnamon bark was the most effective against all the investigated pathogens (MIC: 31.25-125 μL/L) in the VP assay, but clove oil presented the best inhibition against MRSA in liquid medium (MIC: 0.1 mg/mL). Thyme oil also showed antibacterial activity against MRSA and the antibiotic-sensitive strain of P. aeruginosa in both methods. In higher concentration, we found that peppermint oil was effective only in vapor form; contrarily, eucalyptus oil was more efficient in liquid medium. Surprisingly, Scots pine did not show any activity in our test systems. These results suggest that EOs could be promising solutions for the problem of antibiotic resistance due to their multiple composition and complex mode of action. However, more in vivo studies are necessary to calculate the effective dose of EOs in patients and determine their possible side effects and toxicity.

The effectiveness of eucalyptus oil, orange oil, and xylene in dissolving different endodontic sealers

Abstract: Objective: The objective of this study was to evaluate the dissolution effectiveness of eucalyptus oil, orange oil, xylene, and distilled water on three different endodontic sealers. Materials and Methods: About 240 samples of root canal sealers (eighty for each sealer) were prepared and divided into four groups of 20 each for immersion in different organic solvents. Each group was further subdivided into two subgroups (n = 10) for 2 and 10 min of immersion time. The mean percentage of weight loss was determined for each sealer in each solvent at both time periods. Data were statistically analyzed by two factor analysis of variance and significance of mean difference was obtained by Tukey's post hoc test (P Results: The lowest level of solubility was observed for Adseal followed by Apexit Plus and Endomethasone N at both time periods in all solvents. Apexit Plus showed no significant (P > 0.05) difference in its dissolution in all the organic solvents except distilled water at both the time periods. The solubility profile of Endomethasone N and Adseal did not differ significantly among eucalyptus oil, orange oil, and xylene at 2 min and between eucalyptus oil and orange oil at 10 min. However, at 10 min, Endomethasone N and Adseal showed a more pronounced solubility in xylene as compared to both eucalyptus oil and orange oil. Conclusions: In general, xylene was the most effective in dissolving root canal sealers than other organic solvents. Essential oils (eucalyptus oil and orange oil) were found similar in their ability to dissolve Apexit Plus and Endomethasone N.

Antimicrobial Constituents and Effects of Blended Eucalyptus, Rosemary, Patchouli, Pine, and Cajuput Essential Oils.

Abstract: The synergistic antimicrobial activities of blended essential oil preparations composed of eucalyptus, rosemary, patchouli, pine and cajuput oils were evaluated against various pathogenic microorganisms. They exhibited antimicrobial activity in the agar disc diffusion assay against the Gram-positive bacteria, Staphylococcus aureus and S. epidenidis, the Gram-negative bacteria, Escherichia coli and Pseudomonas aeruginosa, and the yeast, Candida albicans. The minimum inhibitory concentration (MIC) of these preparations was evaluated by the broth microdilution method. We found that the best synergistic antibacterial preparation (the sum of fractional inhibitory concentrations, Σfic 1). The blended essential oil preparations were characterized for their components by GC/MS, and contained 1,8-cineole as a major component. However, the preparation containing the highest amount of 1,8-cineole did not exhibit the best synergistic effect, which was shown by the preparation comprising the highest amount of α-pinene. Hence, we concluded that the differential antibacterial effect of either blended oil preparations or single/pure essential oils was influenced by the amount of α-pinene and the number of active components in either the blended preparations or single/pure essential oils.

Toxicity of botanical insecticides on Diaphania hyalinata, their selectivity for the predatory ant Paratrechina sp., and their potential phytotoxicity on pumpkin

Abstract: The use of botanical insecticides could be an alternative efficient pest management in Cucurbitaceae against melonworm Diaphania hyalinata and less harmful to its predator.

Fungi toxic efficiency of some plant volatile essential oils against plant pathogenic fungi

Abstract: Plant essential oils have the potential to replace the synthetic fungicides in the management of different fungal diseases. Four different essential oils of eucalyptus (Eucalyptus globulus), citronella (Cymbopogon citrate), karanj (Pongamia pinnata) and neem (Azadirachta indica) were selected because of their high inhibitory activities against ten phytopathogenic fungi. The antifungal screening for all the four Eos clearly indicates the effective lowest concentration to control the fungal growth. The more lower the MIC value, the better antifungal potency of the relative plant volatile E. globulus. Among the plant volatile essential oils, eucalyptus oil showed the lowest minimum inhibitory concentration (MIC), i.e. 0.5 mg/disc. Higher MIC values were registered, in the order, for citronella, karanj and neem oils, singly used to control all the ten fungal pathogens. Highest zone of inhibition (ZI) values followed the same pattern. These results indicated that plant volatile essential oils after suitable formulation could be used to control of different fungal pathogens. This may encourage the farmers to produce organic commodities to generate more revenue. Key words Essential oils, minimum inhibitory concentration (MIC), zone of inhibition, fungal disease.
