INTRODUCTION Shigella flexneri is a Gram-negative bacteria that has the ability to invade the epithelium of the colon and cause colon ulcers. METHODOLOGY The ability of isolated Shigella flexneri from bloody diarrhea to cause colon ulcers was investigated by histopathological examination via oral administration of the bacteria to adult male albino Sprague-Dawley rats. The antibacterial activi...

This study was conducted to determine the effect of foliar salicylic acid (SA) and citric acid (CA) applications on growth, biochemical characteristics and essential oil content of thyme (Thymus vulgaris L.) grown under field conditions. Salicylic acid (0.5 and 1 mM) and citric acid (5 and 10 mM) were applied three times during the vegetation at 15 day intervals. Results revealed that foliar ap...

the effect of thyme and ajowan essential oils (200µg/l and 300µg/l respectivilly ) on growth of aflatoxin-producing strain of aspergillus parasiticus on 2 stages of pistachio (green and with dry peel ) was studied . also organoleptic tests for evaluating odor and flavor residual of essential oils on pistachio were also performed tested . the collected data were statistically analyzed. the resul...

Studies examining the use of essential oils as replacements for synthetic insecticides require an understanding of the contribution of each constituent present, interactions among these components, and how they relate to overall toxicity. In the present study, the chemical composition of commercial thyme oil was identified by gas chromatography-mass spectrometry. Thyme oil and blends of its maj...

thyme (thymus vulgaris l.) is an important medicinal plant with highly valuable essential oils. in this study, effects of different fertilizer treatments and cuts on thymus vulgaris l. was evaluated in 2008-2009. the research was conducted at alborz research station, research institute of forests and rangelands, karaj, iran. the experimental design was split plot in time in the form of a random...

The larvicidal activity and repellency of 5 plant essential oils--thyme oil, catnip oil, amyris oil, eucalyptus oil, and cinnamon oil--were tested against 3 mosquito species: Aedes albopictus, Ae. aegypti, and Culex pipiens pallens. Larvicidal activity of these essentials oils was evaluated in the laboratory against 4th instars of each of the 3 mosquito species, and amyris oil demonstrated the ...

growth inhibition of aspergillus fumigatus,aspergillus flavus and fusarum solani exposed to the essential oils including thyme, agastache and satureja were studied. disc diffusion method was used to evaluate the fungal growth inhibitory effects of the essential oils. minimal inhibitory concentration (mic) and minimal fungicidal concentration (mfc) of the oils were determined and compared with e...

Growth inhibition of Aspergillus fumigatus,Aspergillus flavus and Fusarum solani exposed to the essential oils including Thyme, Agastache and Satureja were studied. Disc Diffusion Method was used to evaluate the fungal growth inhibitory effects of the essential oils. Minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) of the oils were determined and compared with ...

Eleven essential oils (EOs) were evaluated for their antibacterial properties, against Vancomycin-Resistant Enterococci (VRE) and E. coli O157:H7. EOs were introduced into Brain Heart Infusion agar (BHI) (15ml) at a concentration of 0.25 to 2% (vol/vol) to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) for each pathogen evaluated. Results showe...

a comparative study was made between the acaricidal activities of some essential oils: rosemary (rosmarinus officinalis l.), lavandula (lavandula angustifolia mill.), thyme (thymus vulgaris l.) and ziziphora (ziziphora clinopodioides lam.) on the important mite pest, tetranychus cinnabarinus boisduval, the carmine spider mite, oncut roses during 2010-2012. the sublethal concentrations of ziziph...
