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...

objective: many species of plants present noticeable potency against human bacterial and fungal pathogens. materials and methods: in the current study, antimicrobial activity of the fresh fruits of 4 cultivars (a to d) of malus domestica cultivated in the qamsar area of kashan, iranwas investigated. the disk diffusion and minimal inhibitory concentration (mic) evaluation antimicrobial activity ...

introduction: to assess the antibacterial effects of an iranian endemic essential oil, satureja khuzistanica jamzad (skj) when used as an intracanal antiseptic and interappointment medicament. materials and methods: antimicrobial activity and minimum inhibition concentrations (mics) of skj essential oil with and without calcium hydroxide (ch) against eleven aerobic, microaerophilic and anaerobi...

zhumeria majdae is a rare an endemic medicinal plantspecies grown wild in iran. the hydro distilled essential aerial part oil of z. majdae analysed by gc–ms. thirty-one compounds representing 95.36% of the aerial part oil, respectively, were identified, of which linalool (48.14%), camphor (20.71%), limonene (4.83%), trans-linalool oxide (2.69%), 3-octanone (2.34%), terpinene-4-ol (2.30%), camph...

considering the emergence of antibiotic resistance, scientists are interested in using new antimicrobial agents in the treatment of infectious diseases including infections of the enteric systems. lactic acid bacteria have the great potential to produce antimicrobial compounds that inhibit and control pathogenic bacteria. the aim of this study was to determine the anti-bacterial and anti-adhere...

background and objectives: bacterial resistance to antibiotics has motivated the researchers to evaluate the novel anti-bac- terial compounds such as some thiazole and imidazole derivatives. thereby, in this work, we investigated the anti-bacterial effects of one new thiazole and two new imidazole derivatives on bacillus cereus , listeria monocytogenes , escherichia coli, salmonella typhimurium...

Objective(s): A large ratio of surface to volume of nanoparticles in comparison with bulk ones, will increase the cell penetration and therefore their toxicity. Materials and Methods: Chemical precipitation method was used in order to synthesis of ZnS:Ag quantum dots. Their Physical properties and characteristics were assessed by X-ray diffraction, Ultra Violet-Visible Spectrophotometer, Transm...
