The growing importance of materials that prevent microbial adhesion: antimicrobial effect of medical devices containing silver
(Elsevier B.V., 2009-08-01)
Research has clarified the properties required for polymers that resist bacterial colonisation for use in medical devices. The increase in antibiotic-resistant microorganisms has prompted interest in the use of silver as ...
Potentiation Effect of Iodine Species on the Antimicrobial Capability of Surfaces Coated with Electroactive Phthalocyanines
(American Chemical Society, 2021-12)
The spreading of different infections can occur through direct contact with glass surfaces in commonly used areas. Incorporating the use of alternative therapies in these materials seems essential to reduce and also avoid ...
Antimicrobial action of ozone gas on surfaces and in the air
(Univ Fed Sao Paulo, Dept Enfermagen, 2021-01-01)
Objective: Assess the antimicrobial action of ozone gas (O-3) on surfaces and artificially cooled ambient air. Methods: Cross-sectional experimental/laboratory study carried out in ten rooms of a medical microbiology ...
Chapter 11: Antiviral, Antimicrobial, and Antibiofilm Properties of Biosurfactants
(2021-04-01)
In an era of increasing drug resistance, the search for antimicrobial agents is crucial for the development of a sustainable future. Biosurfactants are amphiphilic molecules with recognised surface tension, and biological ...
The importance of 2D aggregates on the antimicrobial resistance of Staphylococcus aureus sessile bacteria
(Elsevier Science, 2016-04)
Biofilms formed on implanted devices are difficult to eradicate. Adhesion mechanism, high bacterial density, aggregation, induction of persisters and stressed bacteria are some of the factors considered when the antimicrobial ...
Disruption of Saccharomyces cerevisiae by Plantaricin 149 and investigation of its mechanism of action with biomembrane model systems
(ELSEVIER SCIENCE BV, 2009)
The action of a synthetic antimicrobial peptide analog of Plantaricin 149 (Pln149a) against Saccharomyces cerevisiae and its interaction with biomembrane model systems were investigated. Pln149a was shown to inhibit S. ...
Interactions of “de novo” designed peptides with bacterial membranes: Implications in the antimicrobial activity
(Elsevier Science, 2020-11)
Antimicrobial peptides are small molecules that display antimicrobial activity against a wide range of pathogens. In a previous work, by using model membranes we studied P6, a peptide that shows no antimicrobial activity, ...
Nanostructured Antimicrobials in Food Packaging—Recent Advances
(2019-12-01)
Active food packaging systems promote better food quality and/or stability, such as by releasing antimicrobial agents into food. Advantages of adding antimicrobials to the packaging material instead of into the bulk food ...
Antimicrobial-resistant enterobacteria in surface waters with fecal contamination from urban and rural communities
(Sociedade Brasileira de Medicina Tropical, 2021)
