non-steroidal anti-inflammatory drugs (nsaids) have shown antibacterial activity in some recent studies. the aim of this study was to evaluate the antibacterial effect of diclofenac against enterococcus faecalis (e. faecalis) as a resistant endodontic bacterium in comparison with ibuprofen, calcium hydroxide and amoxicillin.the antibacterial activity of materials was evaluated using agar diffus...

background and objective: escherichia coli o157:h7, an emerging pathogen, causes severe enteritis and the extraintestinal complication of hemolytic-uremic syndrome. the goal of this study was to evaluate the conjugate of e. coli o157: h7 lipopolysaccharide (lps) with diphtheria toxoid (dt) as a candidate vaccine in mice model. material and methods: lps from e. coli o157:h7 was extracted by hot ...

With our efforts to develop potent antimicrobial agents, a series of anthracene and 1,8-napthalimide aminothiazole analogues were synthesized characterized by using fundamental spectral analysis. All the hybrids screened for their anti-microbial activities against bacterial strains E. coli, B. subtillis, S. aureus, fungal A. niger C. albicans. Among compounds investigated, 4c, 4d, 6c exhibited ...

Enterohemorrhagic Escherichia coli (EHEC), such as E. coli O157:H7, are emerging food-borne pathogens worldwide. This micro-organism can damage the epithelial tissue of the large intestine. The cytotoxic effects can be neutralized by probiotics such as Bifidobacterium bifidum. Probiotics are viable cells that have beneficial effects on the health of the host. The preventing activity of B. bifid...

Abstract Background and Purpose: In traditional medicine, herbal products still remain the principal source of pharmaceutical agents. The present study aimed to investigate the antifungal effects of Echinophora platyloba and Rosmarinus officinalis extracts on C. albicans species. Materials and Methods: The aqueous and ethanolic leaf extracts of E. platyloba and R. officinalis, collected f...

ABSTRACT: Chemical composition of Lavandula angustifolia was studied by solvent free microwave extraction (SFME) and hydrodistillation (HD) methods. 1, 8-cineole (42.7% and 37.9%), Camphor (26.1% and 21.3%) and Borneol (31.2% and 21.6%) were the major compounds that obtained by SFME and hydrodistillation, respectively. The antibacterial activity of extracted oils was investigated against Gram-p...

background: escherichia coli o157:h7 is a gram-negative and facultative anaerobic food-borne bacterial pathogen. the major purpose of this study was to evaluate physicochemical characteristics of nanoliposome garlic essential oil (eo) and its antibacterial effect on e. coli o157:h7. methods: nanoliposome garlic eo was prepared by ethanol injection method and its physicochemical properties were ...

Unfavorable conditions can affect on secondary metabolites production in the plants. The aim of present study was to evaluate the effect of heavy metals accumulation on antibacterial potential of Chenopodium murale L., Senecio glaucus L., Malva parviflora L. and Calendula arvensis L. grown in an industrial area of steel production in Ahvaz, southwest of Iran. The cadmium (Cd), iron (Fe), mangan...

Enterobacteria, especially Escherichia coli, are abundant in patients with inflammatory bowel disease or colorectal cancer (CRC). However, it is unclear whether cancer is promoted by inflammation-induced expansion of E. coli and/or changes in expression of specific microbial genes. Here we use longitudinal (2, 12 and 20 weeks) 16S rRNA sequencing of luminal microbiota from ex-germ-free mice to ...

introduction: in this study, the chemical composition and antimicrobial activity of essential oil of ziziphora clinopodiodes and its potential application as a natural preservative in reducing the indigenous microbial population of hamburger were investigated. method: essential oil of ziziphora clinopodiodes cultivated in iran was obtained by hydro-distillation method (hdm). chemical compositio...
