Successful infection by Listeria monocytogenes is dependent upon a range of bacterial extracellular proteins including a cytolysin termed listeriolysin O and phosphatidylcholine-specific phospholipase C. Five plant essential oils--bay, clove, cinnamon, nutmeg and thyme--significantly reduced the production of listeriolysin O by L. monocytogenes. The greatest change was observed after culture wi...

The ThYme (Thioester-active enzYme; http://www.enzyme.cbirc.iastate.edu) database has been constructed to bring together amino acid sequences and 3D (tertiary) structures of all the enzymes constituting the fatty acid synthesis and polyketide synthesis cycles. These enzymes are active on thioester-containing substrates, specifically those that are parts of the acyl-CoA synthase, acyl-CoA carbox...

Thyme (Thymus vulgaris) belongs to the Lamiaceae family, and has been used since antiquity in traditional medicine. It is recognized by its therapeutic virtues. The ancient-Iranians were familiar with many medicinal herbs and were aware of their usefulness in treatment of various diseases. In this study Thymus vulgaris L. to evaluate the antimicrobial activity, Disc Diffusion Test with KirbyBau...

The fungicidal effect of some essential oils against Alternaria solani one of the species that cause early blight of potato was evaluated under in vitro and field conditions. Effect of carnation, caraway, thyme oils and the chemical fungicide Ridomil MZ 72 at various concentrations on mycelial growth of A. solani was tested. Carnation oil had the strongest and most extensive inhibitory effect o...

In this study, the effect of water and alcoholic (ethanol) extracts Caper Bush Capparis spinosa L., Cumine Cuminum cyminum L. , Black pepper Piper nigrum Sage Salvia sp. Cat thyme Teucrium polium plants on 4th instar larvae Culex quinquefasciatus have been evaluated .The results showed that extract P. had highest larvae, with 48h LC50 155. 9 ppm followed by ethanol C. 308.2 ,315.1and 791.4 resp...

A method for the extraction of valuable compounds from plants and flowers (viz. laurel, rosemary, thyme, oregano and tuberose) is proposed. The dynamic approach allows go-and-backward circulation of the extractant (ethanol) through the solid sample subjected to the action of an ultrasound probe (thus reducing sample amount and avoiding overpressure). A multivariate optimisation study and applic...

oil on 15 clinical strains of Candida spp., isolated from humans and dogs and to determine if there is a difference in susceptibility between human and dog isolates. Sampling in patients with stomatitis was done by swabbing the denture or oral mucosa swab while sampling in dogs was done by swabbing the oral cavity mucosa after stomatitis has been diagnosed. In order to investigate the antifunga...

In this study, we evaluate the olfactory responses of Mahanarva spectabilis adults to aqueous extracts from following non-host plants for pest insect: garlic (Allium sativum L.), rue (Ruta graveolens cinnamon (Cinnamomum verum J. Presl), lemongrass (Cymbopogon citratus Stapf.), clove (Syzygium aromaticum star anise (Illicium Hook.f), eucalyptus (Eucalyptus globulus Labill.), tobacco (Nicotiana ...

In the Mediterranean zone semi-natural vegetation and diverse mountain-cropping systems have been converted into monocultures with low tree densities, leaving the soil unprotected. Soil loss and runoff over a three-year period were monitored in hillside erosion plots (35% slope and 144 m 2 in area) with almond (Prunus amygdalus) trees under three soil-management systems: no-tillage with sage (S...
