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...
Mucosal pathogens differ from normal flora constituents in that they provoke a host response that upsets mucosal integrity. We investigated whether the elaboration of discrete adherence factors is sufficient to break the inertia of the mucosal barrier. PapG-mediated adherence was selected as an example, because P fimbrial expression characterizes uropathogenic Escherichia coli and because adher...
Introduction: Uropathogenic Escherichia coli (UPEC) is among the primary cause of urinary tract infections (UTIs). This study was conducted to determine the antibiotic resistance pattern of E. coli isolates from UTIs in Kermanshah. Methods: In this study, 180 midstream urine samples were collected from outpatients for five months. Based on differential biochemical tests such as oxidase, Indole,...
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...
Abstract Background and Objective: Escherichia coli, one of the most common causative agents of urinary tract infections (UTIs) acquired from community and hospital, has developed multiple resistances to various antibiotics such as aminoglycosides. The main resistance mechanism to aminoglycosides is inactivation of these drugs by a variety of acetyltransferase, nucleotidyltransferase, and phosp...
In recent years, extra intestinal E. coli infection and a high level of drug resistance among such ExPEC is often seen in the World. The treatment of E. coli infections is increasingly becoming difficult because of the multi-drug resistance exhibited by the organism. As multidrug resistance has spread, we are already coming across infections that cannot be cured with any available antibiotics. ...
Abstract Background and Objective: Escherichia coli is the most common cause of urinary tract infections in children and the leading cause of intra-abdominal infections (peritonitis and abscess) followed intestinal injuries. Urinary tract infection, including cystitis and pyelonephritis, is a common childhood infection. E. coli causes more than 90 percent of the community acquired and 50% of ho...
Although many proteins have been described involved in Escherichia coli colonization and infection, only few reports have shown lectins as important components in these processes. Because the mechanisms underlying E. coli colonization process involving lectins are not fully understood, we sought to identify the presence of other non-described lectins in E. coli. Here, we isolated a 75-kDa prote...
Background:Urinary Tract Infections (UTIs) are the most common infectious diseases in childhood. The Uropathogenic Escherichia coli (UPEC) strains account for as much as 80% of UTIs. Objective:From a clinical perspective, it is important to know which virulence factors and antibiotic resistance properties are present in UPEC strains in pediatrics. Therefore, this study was carried out...
ABSTRACT Background and objectives: Urinary tract infections (UTIs) are one of the most common infectious diseases caused by bacteria. The primary etiologic agent of UTIs is Escherichia coli. Uropathogenic E.coli (UPEC) strains have a number of specific virulence factors, which can worsen UTIs. This study was performed to...
