the aim of this study was to evaluate the ability of 15 serotypes of salmonella to form biofilm on polystyrene, polyvinyl chloride (pvc) and glass surfaces. .initially slime production was assessed on cra agar and hydrophobicity of 20 salmonella strains isolated from poultry and human and two salmonella enterica serovar typhimurium references strains was achieved by microbial adhesion to n-hexa...

The adsorption and assembly of B18 peptide on various solid surfaces were studied by reflectometry techniques and atomic force microscopy. B18 is the minimal membrane binding and fusogenic motif of the sea urchin protein bindin, which mediates the fertilization process. Silicon substrates were modified to obtain hydrophilic charged surfaces (oxide layer and polyelectrolyte multilayers) and hydr...

The entomopathogenic fungus Beauveria bassiana produces at least three distinct single-cell propagules, aerial conidia, vegetative cells termed blastospores, and submerged conidia, which can be isolated from agar plates, from rich broth liquid cultures, and under nutrient limitation conditions in submerged cultures, respectively. Fluorescently labeled fungal cells were used to quantify the kine...

conclusions: these data demonstrated that the attachment of bacteria to hydrophilic acrylic iols was more than hydrophobic pmma ones independent of the brand. according to these results the bacterial strain might have more hydrophilic properties. augmenting the biomass of biofilm by passing of time demonstrated the key role of time in biofilm formation on the iol surfaces. the differences betwe...

Studies have been carried out on the adsorption properties of plasma fibronectin (FN) on hydrophobic and hydrophilic surfaces. The hydrophobic and hydrophilic surfaces used were nonwettable bacteriological dishes and wettable tissue culture dishes, respectively. At low plasma FN concentrations, there was more plasma FN binding to hydrophobic surfaces than to hydrophilic surfaces. Under these co...

Bacteria adhere to almost any surface, despite continuing arguments about the importance of physico-chemical properties of substratum surfaces, such as hydrophobicity and charge in biofilm formation. Nevertheless, in vivo biofilm formation on teeth and also on voice prostheses in laryngectomized patients is less on hydrophobic than on hydrophilic surfaces. With the aid of micro-patterned surfac...

This paper presents the principle, fabricated structure, characterization and results obtained for a new class of surfaces—“hydrophobic non-fouling surfaces”—for droplet-based microfluidics. Building on the theory of wetting of rough surfaces, we have developed novel surfaces which are chemically hydrophilic, i.e., the droplet is in contact with a non-fouling hydrophilic material but exhibits h...
