Comparison of adhesin genes and antimicrobial susceptibilities between uropathogenic and intestinal commensal Escherichia coli strains. [PDF]

PLoS ONE, 2013
The presence of adhesins is arguably an important determinant of pathogenicity for Uropathogenic Escherichia coli (UPEC). Antimicrobial susceptibilities were tested by agar dilution method, fifteen adhesin genes were detected by polymerase chain reaction,

Polyamine production by natural Escherichia coli strains isolated from various sources

Acta Biomedica Scientifica
Background. The polyamines putrescine and cadaverine serve as raw materials for the synthesis of polyamides; their production by microbial synthesis is a current issue of biotechnology, the development of which requires a search for effective producers ...

Evolutionary fine-tuning of conformational ensembles in FimH during host-pathogen interactions [PDF]

, 2017
Positive selection in the two-domain type 1 pilus adhesin FimH enhances Escherichia coli fitness in urinary tract infection (UTI). We report a comprehensive atomic-level view of FimH in two-state conformational ensembles in solution, composed of one low ...

Effects Of Zno Nanoparticles on Initial Adhesion and fimH Gene Expression Level of Uropathogenic Eschercia coli

Journal of Clinical and Basic Research, 2017
Introduction: Uropathogenic Escherichia coli (UPEC) strains are the main causes of urinary tract infections. Adhesion is one of the main and primary steps of UPEC pathogenicity.

Uropathogenic Escherichia coli (UPEC) strains may carry virulence properties of diarrhoeagenic E-coli [PDF]

, 2008
To analyze whether Escherichia coli strains that cause urinary tract infections (UPEC) share virulence characteristics with the diarrheagenic E. coli (DEC) pathotypes and to recognize their genetic diversity, 225 UPEC strains were examined for the ...

Molecular Characterization of Uropathogenic Escherichia coli Reveals Emergence of Drug Resistant O15, O22 and O25 Serogroups

Medicina, 2019
Background and Objectives: Uropathogenic Escherichia coli (UPEC) are common pathogens causing urinary tract infections (UTIs). We aimed to investigate the relationship among clinical manifestation, serogroups, phylogenetic groups, and antimicrobial ...

Characterisation of rpoS alleles in UPEC strain CFT073

Access Microbiology, 2019
Escherichia coli is a major cause of urinary tract infections, bacteraemia and sepsis. CFT073 is a well-studied, prototypic urosepsis isolate. This laboratory has previously shown that strain CFT073 is serum-resistant, with resistance being imparted by factors including capsule and extracellular polysaccharides inter alia.

Molecular Characterization of the Escherichia coli Asymptomatic Bacteriuria Strain 83972: The Taming of a Pathogen [PDF]

, 2006
Escherichia coli is the most common organism associated with asymptomatic bacteriuria (ABU). In contrast to uropathogenic E. coli (UPEC), which causes symptomatic urinary tract infections (UTI), very little is known about the mechanisms by which these ...

The structure of the PapD-PapGII pilin complex reveals an open and flexible P5 pocket [PDF]

, 2012
P pili are hairlike polymeric structures that mediate binding of uropathogenic Escherichia coli to the surface of the kidney via the PapG adhesin at their tips.
