Antimicrobial activity of ethanolic extract Aloe vera were observed against Staphylococcus aureus, pyogenes, saprophyticus, Streptococcus pneumoniae and Escherichia coli, Pseudomonas aeruginosa, Klebsiella . leaf gel was used for extraction.Zones inhibition in millimeter to measure the antimicrobial effect. susceptibility test showed that has growth inhibitory effects tested pathogens. Ethanoli...

Increasing resistances of germs to established antiseptics demand a continuous development of new antimicrobial agents. Therefore, atmospheric pressure plasma was used to produce antimicrobial NaCl-solutions. Its shortand long-term germicidal effects have been investigated by inactivation of Escherichia coli in batches. Liquid changes by plasma exposure that correlate with bacteria inactivation...

Statement of the Problem Orthodontic appliances facilitate microbial plaque accumulation and increase the chance of white spot lesions. There is a need for new plaque control methods independent of patient's cooperation. Purpose The aim of this study was to determine the effects of incorporating copper oxide (CuO) nanoparticles on antimicrobial properties and bond strength of orthodontic adhe...

The aim of this study was to investigate the antimicrobial effect of chitooligosaccharides prepared by chitosanase from Pseudomonas CUY8. Antimicrobial activities of different degrees of deacetylation (DD) and polymerization (DP) of chitooligosaccharides against various species of bacteria and fungi were measured. The antimicrobial effects of chitooligosaccharides compared with chitosan and chi...

BACKGROUND Although the emergence and spread of antibiotic resistance have been well studied for endemic infections, comparably little is understood for epidemic infections such as influenza. The availability of antimicrobial treatments for epidemic diseases raises the urgent question of how to deploy treatments to achieve maximum benefit despite resistance evolution. Recent simulation studies ...

OBJECTIVE In vitro testing of antimicrobial agents is an important tool in the testing hierarchy, and may provide interesting insights into their potential clinical efficacy. Agents with demonstrable in vitro antimicrobial activity may be effective against the same microorganisms in vivo, whereas agents without demonstrable in vitro antimicrobial activity are unlikely to exhibit in vivo antimic...

Over the last decade, decreasing effectiveness of conventional antimicrobial-drugs has caused serious problems due to the rapid emergence of multidrug-resistant pathogens. Furthermore, biofilms, which are microbial communities that cause serious chronic infections and dental plaque, form environments that enhance antimicrobial resistance. As a result, there is a continuous search to overcome or...

Rosa damascena, Tripleurospermum disciforme and Securigera securidaca were used as disinfectant agents and for treatment of some disease in folk medicine of Iran. The antimicrobial effects of different fractions of seeds extract of S. securidaca, petals extract of R. damascena and aerial parts extract of T. disciforme were examined against some gram positive, gram negative and fungi by cup plat...

  Background: Oliveria decumbens Vent. is an endemic plant of Flora Iranica that grows in high temperature areas of south and west of Iran. It is used for indigestion, diarrhea, abdominal pain and fever in traditional medicine.   Objective: In this investigation, chemical composition and antimicrobial effects of Oliveria decumbens has been studied.   Methods: The essential oil of aerial parts o...
