during storage of eggs, unfavorable changes occur due to exertion of co2 and water vapor from through of crust pinholes. one of the practical methods for preventing or reducing these changes is to use biopolymer-based coatings. in this research, five coating solutions based on carboxymethyl cellulose (cmc) and glycerol as plasticizer, oleic acid (1 and 2% v/v) and antimicrobial agents (potassiu...

Antimicrobial biocompatible polymers form a group of highly desirable materials in medicinal technology that exhibit interesting thermal and mechanical properties, and high chemical resistance. There are numerous types of polymers with antimicrobial activity or antimicrobial properties conferred through their proper modification. In this review, we focus on the second type of polymers, especial...

background :  a large number of plants are used for treatment of diseases because of their antimicrobial activities. this study aims to investigate the antimicrobial effects of some plants on the food pathogenic bacteria.   methods : plant extracts were obtained using the rotary system, the minimum inhibitory concentration (mic) by diluting method against bacteria was determined.   results :   ...

New strategies for the prevention or treatment of infections are required. The purpose of this study is to evaluate the effects of antimicrobial peptides and bacteriocins isolated from Lactobacillus plantarum on growth and biofilm formation of three common pathogenic microbes. The antibacterial properties of the antimicrobial peptide Tet213 and bacteriocins were tested by the disc diffusion met...

The progressive public use of antimicrobial clothes has raised issues concerning skin health. A placebo-controlled side-to-side study was run with antimicrobial clothes versus fabrics of similar structure but minus the antimicrobial activity, to evaluate possible adverse effects on the healthy skin microflora. Sixty volunteers were enrolled. Each participant received a set of form-fitting T-shi...

Background:The spread of drug-resistant microbial strains has led many studies for identifying, designing, and synthesizing new antimicrobial agents.The aim of this study was to evaluate antimicrobial effects of some synthesized potassium dithiocarbazinate derivatives against 6 Gram-negative and 4 Gram-positive bacteria as well as 2 molds and 1 yeast. Potassium salts of dithiocarbazinic acids w...

While oral rinses used for cosmetic purposes only do not necessarily have to be antiseptic, antimicrobial activity is required for medical indications, including oral and periodontal surgery. So the question arises-is the antimicrobial activity of oral rinses associated with any destructive changes in cell viability in vitro? To answer this question, we examined twelve oral rinses with respect ...
