Although many strain typing methods exist for pathogenic Escherichia coli, most have drawbacks in terms of resolving power, interpretability, or scalability. For this reason, multilocus sequence typing (MLST) is an appealing alternative. However, its applicability to different pathogens in specific epidemiologic contexts is not well understood. Here, we applied a previously established MLST met...

BACKGROUND Pathogenic strains in Escherichia coli can be divided into several pathotypes according to their virulence features. Among them, uropathogenic E. coli causes most of the urinary tract infections and has a genotype distinct from other virulent strains of E. coli. In this study, we sequenced and analyzed the genome of E. coli NCCP15653 isolated from the feces of a diarrhea patient in 2...

the ability of uropathogenic e. coli (upec) to cause symptomatic uti is associated with the expression of a variety of virulence factors. biofilm formation enables upec to resist the flow of urine and increases its tolerance to antimicrobials and the host immune response. the measurement of biofilm formation in vitro is affected by the type of culture medium used. the aim of this study was to e...

Quinolones and fluoroquinolones are widely used to treat uropathogenic Escherichia coli infections. Bacterial resistance to these antimicrobials primarily involves mutations in gyrA and parC genes. To date, no studies have examined the potential relationship between biochemical characteristics and quinolone resistance in uropathogenic E. coli strains. The present work analyzed the quinolone sen...

Background and Objective: Escherichia coli strains are the major cause of urinary tract infections which belong to the large group of extra-intestinal pathogenic E. coli. They fall into four main phylogenetic groups: A, B1, B2 and D. The aim of the present study was to determine phylogenetic groups in uropathogenic and commensal Escherichia coli isolated. Also, due to increase in the rate of an...

abstract bachground and objectives: the ability of adherence to the surface of host cell is very critical in the colonization of microbial pathogens. it has been revealed that e. coli strains that infect urinary tracts have different fimbrea such as i, s, fic, dr, and fimbrial adhesions. material and methods: in this study, 363 urine samples were obtained from patients with urinary tract infect...

results we found a high number of pai markers such as pai icft073, pai iicft073, pai i536, pai iv536, pai ii j96 and pai ii536 significantly associated with upec. the pai iv536 was the most detected ones among fecal e. coli isolated from healthy people while pai i536, pai ii536 and pai ij96 were not seen. pcr phylogenetic groups typing revealed that uropathogenic strains were mainly found in b2...

INTRODUCTION Escherichia coli (E. coli) is the most common cause of urinary infections in hospitals. The aim of this study was to evaluate the ERIC-PCR method for molecular typing of uropathogenic E. coli strains isolated from hospitalized patients. METHODS In a cross sectional study, 98 E. coli samples were collected from urine samples taken from patients admitted to Baqiyatallah Hospital fr...

The objective of this work was the phylogenetic characterization of local clinical isolates of uropathogenic E. coli with respect to drug resistance. A total of 59 uropathogenic E. coli responsible for community acquired urinary tract infections were included in this study. A triplex PCR was employed to segregate each isolate into four different phylogenetic groups (A, B1, B2 and D). Drug resis...

background and objectives: urinary tract infection (uti) is one of the most common infections in human, and uropathogenic escherichia coli (upec) strains are the most common cause of uti. these strains colonize in bladder and cause cystitis, which could cause pyelonephritis by movement to the kidneys. since fimh protein has a very important role in colonization of upec strains and causing infec...
