Uropathogenic Escherichia coli is the causative agent for >80% of uncomplicated urinary tract infections (UTIs). Uropathogenic E. coli strains express a number of virulence and fitness factors that allow successful colonization of the mammalian bladder. To combat this, the host has distinct mechanisms to prevent adherence to the bladder wall and to detect and kill uropathogenic E. coli in the e...
Escherichia coli represents the primary etiological agent responsible for urinary tract infections, one of the most common infections in humans. We report here the complete genome sequence of uropathogenic Escherichia coli strain CI5, a clinical pyelonephritis isolate used for studying pathogenesis.
A total of 88 uropathogenic Escherichia coli isolates, including 68 isolates from urine and 20 isolates from blood, were characterized by multilocus sequence typing (MLST). MLST has identified an important genetic lineage of E. coli, designated sequence type 131 (ST-131), represented by 52 of these isolates, 51 of which were resistant to extended-spectrum cephalosporins. ST-131 appears to be a ...
background: one of the most common infections in human is urinary tract infection (uti) and uropathogenic escherichia coli is one of its major causative agents . uti is extremely common among young women. children under age 5 are also highly at risk. considering the prevalence of this disease, it is necessary to design an appropriate diagnostic method for its effective diagnos...
Extra-intestinal pathogenic E. coli (ExPEC) infections are common in mammals and birds. The predominant ExPEC types are avian pathogenic E. coli (APEC), neonatal meningitis causing E. coli/meningitis associated E. coli (NMEC/MAEC), and uropathogenic E. coli (UPEC). Many reviews have described current knowledge on ExPEC infection strategies and virulence factors, especially for UPEC. However, su...
This review discusses recent advances in the understanding of how the common pathogen, uropathogenic Escherichia coli, interacts with the host to lead to infection.
Background and Aim: Uropathogenic Escherichia coli (UPEC) strains are a causative agent in most of the urinary tract infections (UTIs), which constitute a multitude of virulence factors. There is little information about phylogenetic group distribution, types, and their virulence factors in Uropathogenic Escherichia coli (UPEC) in different areas of Iran. In the present study, the phylogenic pa...
BACKGROUND Ureters are fundamental for keeping kidneys free from uropathogenic Escherichia coli (UPEC), but we have shown that 2 strains (J96 and 536) can subvert this role and reduce ureteric contractility. To determine whether this is (1) a widespread feature of UPEC, (2) exhibited only by UPEC, and (3) dependent upon type 1 fimbriae, we analyzed strains representing epidemiologically importa...
A variety of virulence factors (VFs) such as type 1 fimbriae, pilus associated with pyelonephritis, S fimbriae, afimbrial adhesin, alpha-hemolysin, aerobactin and cytotoxic necrotizing factor 1 are associated with uropathogenic Escherichia coli. In this study, 80 uropathogenic E. coli strains in 50 dogs and 30 cats suffering from UTI. In addition, 60 E. coli strains were isolated from fecal sam...
Investigation into the pathogenesis of Escherichia coli urinary tract infection has provided numerous insights into the mechanisms by which bacteria adhere, grow and persist in association with host tissue. Many molecular details concerning the interaction of these bacteria with their host have been elucidated, and the murine model of cystitis has generated a new paradigm by which acute and rec...
