Impact of Various Environmental and Growth Conditions on Antigen 43 Gene Expression and Biofilm Formation by Uropathogenic Echserchia coli
ABSTRACT Background and Objectives: Biofilm is a population of bacteria growing on a surface and enclosed in an exopolysaccharides matrix, which increases resistance to antimicrobial agents and immune response. Uropathogenic Escherichia coli (UPEC) are biofilm-forming bacteria and the most common cause of urinary tract infections (UTIs). This study ev...
متن کاملEvaluation of Antibiotic Resistance and Biofilm Formation Ability Uropathogenic E. coli (UPEC) Isolated From Pregnant Women in Karaj
Background and Objective: Uropathogenic Escherichia coli (UPEC) are the most common cause of urinary tract infections. The binding of these bacteria to epithelial cells and the formation of biofilms cause these bacteria to be further colonized and difficult to remove in the urinary tract. This study aimed to determine the antibiotic resistance and to evaluate the biofilm formation power in Esch...
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 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 کاملThe ability of uropathogenic Escherichia coli isolates in biofilm formation on urinary catheter and association with bcsA and draE genes
The product biofilm by E.coli strain can cause serious problem for human health. Catheter is considered to be s suitable place for colonization of microorganisms, so that in %5-10 of patients who used catheter for only one day and also in all patients who used it for over 28 days, this colonization of bacteria is observed on catheter. This study is come out in order to compare biofilm formation...
