Relationship of cell surface hydrophobicity with biofilm formation and growth rate: A study on Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli
Objective(s): This study was designed to determine the relationship of Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli isolates in multispecies biofilms and their individual phenotypic characters in biofilm consortia. Materials and Methods: The subject isolates were recovered from different food samples and identified on the basis of growth on differential and selective med...
متن کاملZinc oxide nanoparticle reduced biofilm formation and antigen 43 expressions in uropathogenic Escherichia coli
Objective(s): This study aimed to investigate the effect of zinc oxide nanoparticles (ZnO-np) on biofilm formation and expression of the flu gene in uropathogenic Escherichia coli (UPEC) strains. Materials and Methods: Minimum inhibitory concentration (MIC) of ZnO-np was determined by agar dilution method. The effect of MIC and sub-MIC concentrations of ZnO-np on biofilm formation were determin...
متن کاملRemoval of nickel and total chromium using Escherichia coli biofilm supported on clinoptilolite
-Biofilm is communities of microorganisms attached to the surface and is able to concentrate metal species within their cell structure. Therefore, the aim of this study was to produce Escherichia coli biofilm on zeolite (clinoptilolite) and evaluate its ability for nickel (Ni) and chromium (Cr) adsorption from aqueous solutions. A laboratory-scale batch model was used for biodsorption assay. Th...
متن کاملInvestigation of Biofilm ability by Microtiter Plate Method in uropathogenic Escherichia coli isolated from patients with urinary tract infection with urinary stones.
Abstract: Background and Aim: Urinary tract infections are one of the most commonly reported nosocomial infections caused by colonization of E. coli in the mucosal epithelium and in the formation of microbial biofilms, which damage the host tissue. The aim of this study was to determine the amount of biofilm formation of uropathogenic E. coli based on urinary tract stones of people with urin...
متن کاملComplex regulatory network controls initial adhesion and biofilm formation in Escherichia coli via regulation of the csgD gene.
The Escherichia coli OmpR/EnvZ two-component regulatory system, which senses environmental osmolarity, also regulates biofilm formation. Up mutations in the ompR gene, such as the ompR234 mutation, stimulate laboratory strains of E. coli to grow as a biofilm community rather than in a planktonic state. In this report, we show that the OmpR234 protein promotes biofilm formation by binding the cs...
