Genome and plasmid diversity of Extended-Spectrum β-Lactamase-producing Escherichia coli ST131 – tracking phylogenetic trajectories with Bayesian inference

Scientific Reports, 2019
Clonal lineages of ESBL (Extended-Spectrum β-Lactamase)-producing E. coli belonging to sequence type 131 (ST131) have disseminated globally during the last 30 years, leading to an increased prevalence of resistance to fluoroquinolones and extended ...

Biofilm formation and antimicrobial resistance pattern of uropathogenic E. coli ST131 isolated from children with malignant tumors

Journal of antibiotics (Tokyo. 1968)
The multidrug-resistant clone identified as Escherichia coli sequence type 131 ( E. coli ST131) has spread world-wide. This study sought to ascertain the frequency and biofilm formation of E. coli ST131 isolated from children with various malignancies. A

Pathogenicity Islands in Uropathogenic Escherichia coli Clinical Isolate of the Globally Disseminated O25:H4-ST131 Pandemic Clonal Lineage: First Report from Egypt

Antibiotics, 2022
Uropathogenic Escherichia coli (UPEC) is the main etiological agent of urinary tract infections (UTIs). The pathogenesis of UTIs relies upon UPEC’s acquisition of virulence determinants that are commonly inserted into large chromosomal blocks which are ...

Overexpression of Escherichia coli yaiX Confers Multidrug Resistance and Enhances Virulence in the Silkworm Infection Model

Microbiology and Immunology, Volume 70, Issue 4, Page 193-205, April 2026.
ABSTRACT The emergence of bacteria with both antimicrobial resistance and high virulence has become a global health concern, underscoring the urgent need to elucidate the molecular basis underlying these traits. Here, we employed the silkworm (Bombyx mori) infection model, which is suitable for high‐throughput screening, together with an Escherichia ...

Evolution of ceftazidime-avibactam and cefiderocol resistance in ST131-H30R1-Escherichia coli isolates with KPC-3 mutants and application of FTIR biotyping

Microbiology spectrum
Ceftazidime-avibactam and cefiderocol represent two of the few alternatives for infections by KPC-producing Enterobacterales. We reported the emergence of resistance to both ceftazidime-avibactam and cefiderocol in a KPC-producing ST131-Escherichia coli (

Hospital-diagnosed infections with Escherichia coli clonal group ST131 are mostly acquired in the community

Scientific Reports, 2021
The worldwide spread of E. coli ST131 has significantly contributed to the dissemination of E. coli producing extended-spectrum β-lactamases (ESBL). In a French University hospital, we assessed the molecular features of ESBL-producing E.

Horizontal transfer of antibiotic resistance genes on abiotic touch surfaces: implications for public health

, 2012
Horizontal gene transfer (HGT) is largely responsible for increasing incidence of antibiotic-resistant infections worldwide. Whilst studies have focussed on HGT in vivo, this work investigates whether the ability of pathogens to persist in the ...
