Background and Objective: Escherichia coli (E-coli) is a normal gram negative organism that inhabit the human and animal intestinal tract. Pap G gene has an important role in creating P -fimbriae tip and in producing septicemia and urinary tract infection. The aim of this study was to investigate the presence of pap G gene in EPEC strains isolated from urine and blood. Materials and Metho...
Charlotte Sahlberg Bang (2016): Carbon monoxide and nitric oxide as antimicrobial agents -focus on ESBL-producing uropathogenic E. coli. Örebro Studies in Medicine 136. Urinary tract infections (UTI) are common in humans and most often caused by uropathogenic Escherichia coli (E. coli). Extended-spectrum beta-lactamase (ESBL)-producing E. coli are increasing worldwide and they are frequently mu...
Urinary tract infections, caused mainly by Escherichia coli, are among the most common infectious diseases. Most isolates of the uropathogenic E.coli can express type 1 and P fimbriae containing adhesins that recognize cell receptors. While P fimbriae recognize kidney glycolipid receptors and are involved in peyelonephritis, the urothelial for type 1 fimbriae were not identified. We show that t...
The low efficacy of current conventional treatments for bacterial infections increases mortality rates worldwide. To alleviate this global health problem, we propose drug-free enzyme-based nanomotors the treatment urinary-tract infections. We develop consisting mesoporous silica nanoparticles (MSNPs) that were functionalized with either urease (U-MSNPs), lysozyme (L-MSNPs), or and (M-MSNPs), us...
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...
مقدمه: باکتری escherichia coli، توانایی ایجاد عفونت مجاری ادراری را دارد و تحت عنوان سویه های ایجاد کننده ی عفونت ادراری (upec یا uropathogenic escherichia coli) نامیده می شود. escherichia coli عامل عفونت ادراری انواع مختلفی از adhesin مانند adhesinهای پیلی (pap یا pyelonephritis associated pili) را بیان می کند که واسطه ی اتصال به سطح سلول های اپی تلیال مجاری ادراری می باشند. پیلی یا فیمبریه ی ...
Due to the genetic similarity of pathogenic Escherichia coli isolated from birds and pathotypes human origin, it is suggested that they have a common ancestor may exchange virulence-associated genes. This study aimed detect genes in E. strains Red-browed Amazon parrot (Amazona rhodocorytha) kept at conservation institute Brazil. High variability virulence was observed, since 12 profiles were fo...
The binding of uropathogenic Escherichia coli is mediated at the tips of pili by the PapG adhesin, which recognizes the Galalpha(1-4)Gal disaccharide on the uroepithelial surface. These receptors have been identified unequivocally in the human and murine urinary tracts but not in intestinal epithelium, yet uropathogenic E. coli strains are commonly found in normal colonic microflora. The gastro...
