Resistance of microorganisms to antibiotics has increased. The use of natural components with antimicrobial properties can be of great significance to reduce this problem. The presented work is focused on the study of the effect of encapsulation of selected plant and animal antimicrobial substances (herbs, spices, lysozyme and nisin) on their activity and stability. Antimicrobial components wer...

Most integral endpoints of the antimicrobial effect are determined over an arbitrarily chosen time period, such as the dosing interval (tau), regardless of the actual effect duration. Unlike the tau-related endpoints, the intensity of the antimicrobial effect (I(E)) does consider its duration-from time zero to the time when bacterial counts on the regrowth curve achieve the same maximal numbers...

background: essential oils of medicinal plants such as chamomile are very complex natural mixtures which can contain compounds at quite different concentrations and some of their components have antioxidant and antimicrobial activities in foodstuff. objective: the antioxidant and antimicrobial effects of chamomile essential oil in cake preparation were evaluated during 75 days of storage. metho...

Recently, the effects of antimicrobial activity of silver nanoparticles was considered by researcher because of Bacterial resistance to antimicrobial agents in chemical.The aim of this study was to evaluate the antimicrobial activity of the gold nanoparticles on Escherichia coli. Gold nanoparticles are chemically synthesized. Standard strain of E. coli was cultured in a nutrient broth. Minimum ...

Introduction: Denture stomatitis is a common complication in patients wearing dentures and preventing the proliferation of related microorganisms and their induced infections is noteworthy. The aim of the present study was to assess the antimicrobial effect of acrylic resins containing various concentrations of silver nanoparticles, on Candida albicans and Streptococcus mutans. Materials and Me...

Background & Aims: Microorganisms are protected from antimicrobial agents when placed in biofilm structure. Biofilm-producing microorganisms are responsible for many problems in industry and medicine; therefore, it is essential to find new techniques for removing and inhibiting biofilms. This study aimed to examine the antimicrobial effect of Eucalyptus camaldulensis alcoholic extracts against ...

conclusions the study results showed that stimulation of the american cockroach’s immunity system lead to production of antibacterial proteins and peptides which had inhibitory effect on the bacteria, depending on the bacterial strains and their sensitivity. likely this feature of insects can be used as therapeutic strategies to produce natural antimicrobial compounds against the pathogenic bac...

Recent research has increased our knowledge and understanding of the antimicrobial effect of marine Streptomyces. In a systematic screening effect, Streptomyces isolates from different marine seaweeds were investigated for antimicrobial activity against Vibrio pathogens (V. harveyji, V. parahemolyticus, V. vulnificus and V. algniolyticus) and potentially active secondary metabolites. The differ...

objective: punica granatum, commonly known as pomegranate, has emerged as a medicinal plant with potential antimicrobial activity. the present study was planned to evaluate this activity against both gram positive staphylococcus aureus (s. aureus) and negative pseudomonas aeruginosa (p. aeruginosa) bacteria as well as against pathogenic yeast, candida albicans (c. albicans). material and method...
