regarding increasing rate of drug resistance among microbial pathogens, a global search to find new antimicrobial agents from natural compounds with fewer side effects has been considered by many researchers worldwide. bioactive compounds with good antimicrobial activity have been isolated from different algae and cyanobacteria. the current study was performed to determine antimicrobial potenti...

the genus teucrium (germander) belongs to the family lamiaceae, within the subfamily ajugoideae .teucrium polium l. (labiatae) has long been recognized in folk medicine in the treatment of many pathophysiological implications, such as gastrointestinal disorders, inflammations, diabetes and rheumatism. in this study antimicrobial activity of two crude extracts obtained from teucrium polium l. wa...

abstract       background and objective: probiotics are living microorganisms that have beneficial effects on the health of digestive system. the aim of this study was to evaluate the antimicrobial ability of acidic and neutral supernatants (culture supernatant) of lactic acid bacteria against common bacterial pathogens.        methods: four species of lactic acid bacteria (lactobacillus planta...

background: essential oils and their major constituents are useful sources of antimicrobial compounds. there are a few reports on the decontamination and antimicrobial activity of essential oils towards shigella spp. m aterials and methods: in this study, the antimicrobial and decontamination potentials of essential oils at different concentrations, belonging to plants such as thymus vulgaris, ...

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-ei...

BACKGROUND The global problem of increasing trend in antimicrobial resistance is particularly pressing in the developing countries, where the Methicillin-Resistant Staphylococcus aureus (MRSA) is often the severe casual agent in hospital-acquired infections. METHODS This multi-centre surveillance prospective study was planned to define the magnitude of problem of MRSA among clinical isolates ...

We present a quantitative estimate of the accuracy of the calculated diffusion coefficients, by comparing predictions of solar models with observational data provided by helioseismology. By taking into account the major uncertainties in building solar models we conclude that helioseismology confirms the diffusion efficiency adopted in SSM calculations, to the 10% level.

male and female leaves and fruits of eleven different taxons of iranian conifers (cupressus sempervirens var. horizontalis, c. sempervirens var. sempervirens, c. sempervirens cv. cereifeormis, juniperus communis subsp. hemisphaerica, j. excelsa subsp. excelsa, j. excelsa subsp. polycarpos, j. foetidissima, j. oblonga, j. sabina, platycladus orientalis and taxus baccata) were collected from diff...
