Background: Yogurt is one of the most popular food diets with refreshing taste, nutritional, and health benefits. The objective of this study was to investigate the effect of three herbal Essential Oils (EOs) including peppermint, basil, and zataria on viability of the probiotic bacteria in yogurt samples and to evaluate the antimicrobial activities of the produced probiotic yogurts against Esc...
A new phthalide, namely 7-methoxy-3-propylidenephthalide (1), along with two known compounds (2, 3) were isolated from the roots of the edible herb Levisticum officinale W.D.J. Koch, commonly known as lovage and well known in traditional medicine for its spasmolytic and diuretic effects. The structure of the new compound was established by HRMS and 1D & 2D NMR (1H 1H COSY, HMQC, and HMBC) spect...
Objective: Antibacterial properties of silver nanoparticles have recently come into the spotlight in endodontic therapy. This study was conducted aiming at comparing the antimicrobial activity of a new irrigation solution containing nanosilver particles with that of sodium hypochlorite and chlorhexidine against Escherichia coli, Enterococcus faecalis, Pseudomonas aeruginosa and Candida albicans...
background: the current study aimed to determine the effect and properties of surface-modified copper doped cu:zno nps on killing curves of bacterial pathogens. m ethods: preparation of in situ surface-modified copper doped zno nanoparticles (cu:zno nps) was done according to standard procedure.assay for antimicrobial activity of cu:zno nps against bacterial pathogens was carried out...
Background and Objective: This study aimed to determine the antibacterial activity of either zinc oxide or copper oxide nanoparticles alone or combined against Gram-positive and Gram-negative bacteria. Materials and Methods: In this experimental study Escherichia coli (E. coli ATCC 25922), Staphylococcus aureus (S.aureus ATCC 25923), Pesudomonas aueroginosa (P. aueroginosa ATCC 27853) and Staph...
Introduction: Enterohemorrhagic Escherichia coli (EHEC) and serotype O157: H7 is one of the most important diseases causing diarrhea. Shiga-like toxin secreted by the bacteria destroys epithelial cells and, in acute cases, causes hemolytic uremic syndrome (HUS). Antibiotic therapy is not effective against this pathogen, because it increases the production of Shiga toxin. Designing chimeric immu...
Background & Objective: Food poisonings caused by consumption of domestic dairy products such as cheese due to Escherichia coli (E.coli) and Staphylococcus aureus (S.aureus) are one of the hygienic problems in foodstuffs. Nowadays, using natural preservatives instead of synthetic preservatives in foods has been regarded increasingly and among these natural compounds, medicinal plants comprise t...

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...
