Background & Objectives: Resistance to antibiotic and also the side effects of drug consumption are the main problem in antibiotic treatment. Therefore, after doing researches on the plants properties, humankind has attempted to use them in different industries. In this investigation the anti-microbial effects of ethanolic extracts of four medicinal plants from Ardebil province include Nepeta n...
Background: Actinomycetes have significant biosynthetic potential of secondary metabolites and promising resource for drug industry. These secondary metabolitesare diverse in biological, chemical structures and functions and the most prolific source of antimicrobial compounds. Most of these antimicrobial have beenisolated from soil-derived actinomycetes of the genus Streptomyces. The aim of thi...
Background and Aim: Mouthwashes are one of the tools used to reduce decay. Fluorin total mouthwash is a new mouthwash, so far no research has been done on its effect on streptococcus mutans. Materials and Methods: In this study, the diameter of growth inhibition zone for streptococcus mutans bacteria was compared between fluorin total and chlorhexidine mouthwash. First, we cultured the bacteri...
Objective(s): The application of synthetic antimicrobial and antifungal compounds is reducing in the last decades in the food and nutrition fields owing to their various side effects and increasing interest of consumers to eat natural foodstuffs without artificial constituents. Clove (Syzygium aromaticum) has numerous medicinal properties, including analgesic, antiseptic, stimulants, carminativ...
Background and Purpose: Treatment of life-threatening fungal infections caused by Candida species has become a major problem. Candida spp. are the most important causative agents of candidiasis. Allium tripedale is a medicinal plant that has been traditionally used to treat infections. In the present study, we aimed to determine the chemical compounds and antimicrobial activity of hydroalcoholi...
herbal medicinal products have attracted significant research interest in recent years. considering the efficiency of algae products in controlling pathogenic bacteria and also easy access to large resources of algae, this study was conducted to evaluate the effects of methanolic, chloroformic and aqueous extracts of gracilaria salicornia against aeromonas hydrophila , a heterotrophic, gram-neg...
The circuitry of the olfactory bulb contains a precise anatomical map that links isofunctional regions within each olfactory bulb. This intrabulbar map forms perinatally and undergoes activity-dependent refinement during the first postnatal weeks. Although this map retains its plasticity throughout adulthood, its organization is remarkably stable despite the addition of millions of new neurons ...
Background: Essential Oils (EOs) are natural metabolic products of plants that contain a condensed chemical hydrophobic liquid compounds. The aim of this study was to evaluate inhibitory effects of EOs of Cinnamon zeylanicum and Myristica fragrans against Brucella abortus 544 inoculated in fresh Baladi cheese. Methods: Fresh Baladi cheese was manufactured from experimentally contaminated milk ...
The aac(6')-Iz gene of Stenotrophomonas maltophilia BM2690 encoding an aminoglycoside 6'-N-acetyltransferase was characterized. The gene was identified as a coding sequence of 462 bp corresponding to a protein with a calculated mass of 16,506 Da, a value in good agreement with that of ca. 16,000 found by in vitro coupled transcription-translation. Analysis of the deduced amino acid sequence ind...
