background: uropathogenic escherichia coli o- serogroups with their virulence factors are the most prevalent causes of utis. objectives: the present investigation was performed to study the virulence factors and o-serogroups profiles of upec isolated from iranian pediatric patients. patients and methods: this cross sectional investigation was performed on 100 urine samples collected from hospit...

Objective(s): Escherichia coli is the key pathogen in the family producing ESBL (extended spectrum β-lactamase) and associated with community-acquired infections. Therefore, this study was planned to determine the antibiotic susceptibility pattern of uropathogenic E. coli, prevalence of the ESBL gene group and class 1 integrons.Materials and Methods: Clinical isolates of uropathogenic E. coli w...

Extraintestinal Escherichia coli (ExPEC), a heterogeneous group of pathogens, encompasses avian, neonatal meningitis, and uropathogenic E. coli strains. While several virulence factors are associated with ExPEC, there is no core set of virulence factors that can be used to definitively differentiate these pathotypes. Here we describe a multiplex of four virulence factor-encoding genes, yfcV, va...

conclusions the results of this study indicated that more than 90% of e. coli isolates harbored the fimh gene. the high binding ability of fimh could result in the increased pathogenicity of e. coli; thus, fimh could be used as a possible diagnostic marker and/or vaccine candidate. materials and methods a total of 140 isolated e. coli strains from patients with uti were identified using biochem...

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...

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...

Because uropathogenic Escherichia coli are better adapted than other E. coli to the urethra, periurethra, and vagina, the authors reasoned that uropathogenic E. coli would be more likely than commensal E. coli to be shared between sex partners. In this 1996-1999 Michigan study, the genetic identity of E. coli isolated from 166 women with E. coli urinary tract infection (UTI) and 94 women withou...

background: uropathogenic escherichia coli (upec) are major bacterial agent of urinary tract infection (uti). this infection is more prevalent among women because approximately half of all women will experience a uti in their life-time and near a quarter of them will have a recurrent infection within 6–12 months. iuta protein has a major role during upec pathogenesis and consequently infection....
