Characterization of Virulence Genetic Profile and Potential Effect of Nanoparticles against Multidrug-Resistant Uropathogenic E. coli at Menuofia University Hospitals

Journal of Pure and Applied Microbiology
One of the most significant pathogens involved in urinary tract infections is Uropathogenic E. coli (UPEC). In addition to assessing biofilm production and the effect of gold and silver nanoparticles on the isolated strains’ ability to form biofilms, the

Phylogenetic Group B2 Expressed Significant Biofilm Formation among Drug Resistant Uropathogenic Escherichia coli

Libyan Journal of Medicine, 2021
Biofilm is an important virulent marker attributed to the development of urinary tract infections (UTIs) by uropathogenic E. coli (UPEC). Drug-resistant and biofilm-producing UPEC are highly problematic causing catheter-associated or recurrent UTIs with ...

Structural and Biophysical Comparison of UPEC and ETEC Adhesion Fimbriae [PDF]

Biophysical Journal, 2015
Adhesion fimbriae (pili) of uropathogenic and enterotoxigenic Escherichia coli (UPEC and ETEC, respectively) facilitate adherence of the bacteria to target cells.

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 ...

Characterization of Phylogroups, Virulence Factors and Antimicrobial Resistance in Canine Pyometra‐associated Escherichia coli

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study characterized 56 Escherichia coli isolates obtained from canine pyometra, which predominantly belonged to phylogroup B2 and harboured multiple virulence genes, with high multidrug resistance rates indicating potential clinical and zoonotic risks. ABSTRACT The presence of multidrug‐resistant extraintestinal pathogenic Escherichia coli (ExPEC)

Interleukin-6 Limits Host Susceptibility to Urinary Tract Infection by Promoting Urothelial Expulsion of Intracellular Bacteria

Journal of Innate Immunity
Introduction: Interleukin (IL)-6 has an important role in limiting urinary tract infection (UTI). Mice lacking IL-6 are more susceptible to uropathogenic Escherichia coli (UPEC), including increased formation of intracellular bacterial ...

Better 10‐Year Cerebrovascular Outcome After Transplant Than on Standard‐Care in Sickle Cell Anemia: DREPAGREFFE Trial

American Journal of Hematology, Volume 101, Issue 8, Page 1799-1817, August 2026.
ABSTRACT Management of cerebral vasculopathy in sickle cell anemia (SCA) includes standard‐care, that is, chronic transfusion (CT) or hydroxyurea, and hematopoietic cell transplantation (HCT). DREPAGREFFE‐1 (December 2010/June 2013), a French multicenter trial, was the first prospective trial comparing standard‐care to match sibling donor (MSD)‐HCT in ...

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.

Bacteriophage-mediated reduction of uropathogenic E. coli from the urogenital epithelium

Infection and Immunity
Urinary tract infections (UTIs), primarily caused by uropathogenic Escherichia coli (UPEC), affect millions annually. UPEC gains access to the urinary tract through mucosal reservoirs, including the vaginal tract.

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 ...
