Virulence Potential and Genomic Mapping of the Worldwide Clone Escherichia coli ST131

PLoS ONE, 2012
Recently, the worldwide propagation of clonal CTX-M-15-producing Escherichia coli isolates, namely ST131 and O25b:H4, has been reported. Like the majority of extra-intestinal pathogenic E. coli isolates, the pandemic clone ST131 belongs to phylogenetic group B2, and has recently been shown to be highly virulent in a mouse model, even though it lacks ...

Genomic epidemiology reveals geographical clustering of multidrug-resistant Escherichia coli ST131 associated with bacteraemia in Wales

Nature Communications
Antibiotic resistance is a significant global public health concern. Uropathogenic Escherichia coli sequence type (ST)131, a widely prevalent multidrug-resistant clone, is frequently associated with bacteraemia.

Escherichia coli ST131- H 22 as a Foodborne Uropathogen [PDF]

mBio, 2018
E. coli ST131 is an important extraintestinal pathogen that can colonize the gastrointestinal tracts of humans and food animals. Here, we combined detection of accessory traits associated with avian adaptation (ColV plasmids) with high-resolution phylogenetics to quantify the portion of human infections caused by ST131 strains ...

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

Molecular epidemiology of CTX-M-producing escherichia coli isolates at a tertiary medical center in western pennsylvania [PDF]

, 2009
A combination of phenotypic and genotypic methods was used to investigate 70 unique Escherichia coli clinical isolates identified as producing extended-spectrum beta-lactamases (ESBLs) at a medical center in Pittsburgh, PA, between 2007 and 2008.

Bacteremia Caused by Extended-Spectrum-β-Lactamase-Producing Escherichia coli Sequence Type ST131 and Non-ST131 Clones: Comparison of Demographic Data, Clinical Features, and Mortality [PDF]

Antimicrobial Agents and Chemotherapy, 2011
ABSTRACT Escherichia coli producing the highly virulent, multidrug-resistant, CTX-M-15 extended-spectrum β-lactamase (ESBL), sequence type 131 (ST131), has emerged on three continents since the late 2000s. We described the molecular epidemiology, clinical features, and outcome of ESBL-producing E. coli

Genomic Epidemiology of C2/H30Rx and C1-M27 Subclades of Escherichia coli ST131 Isolates from Clinical Blood Samples in Hungary

Antibiotics
Extended-spectrum β-lactamase-producing Escherichia coli ST131 has become widespread worldwide. This study aims to characterize the virulome, resistome, and population structure of E. coli ST131 isolates from clinical blood samples in Hungary. A total of

Antibacterial Potential of Actinomycete Extracts and Characterization of β‐Lactamase‐Producing Multidrug‐Resistant Uropathogenic Escherichia coli

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Antibacterial Potential of Actinomycete Extracts Against Multidrug‐Resistant Escherichia coli in Babil Province, Iraq. ABSTRACT The increasing prevalence of multidrug‐resistant (MDR) uropathogenic Escherichia coli (UPEC) strains, particularly those producing β‐lactamase enzymes, complicates urinary tract infection (UTI) treatment and poses a ...

Escherichia coli ST131: a multidrug-resistant clone primed for global domination [PDF]

F1000Research, 2017
A single extra-intestinal pathogenic Escherichia coli (ExPEC) clone, named sequence type (ST) 131, is responsible for millions of global antimicrobial-resistant (AMR) infections annually. Population genetics indicate that ST131 consists of different clades (i.e. A, B, and C); however, clade C is the most dominant globally.

Colonisation with ESBL-producing and carbapenemase-producing Enterobacteriaceae, vancomycin-resistant enterococci, and meticillin-resistant Staphylococcus aureus in a long-term care facility over one year. [PDF]

, 2015
BACKGROUND: This study examined colonisation with and characteristics of antimicrobial-resistant organisms among residents of a long-term care facility (LTCF) over one year, including strain persistence and molecular diversity among isolates of extended ...
