Escherichia coli ST131, an Intriguing Clonal Group [PDF]

Clinical Microbiology Reviews, 2014
SUMMARY In 2008, a previously unknown Escherichia coli clonal group, sequence type 131 (ST131), was identified on three continents. Today, ST131 is the predominant E. coli lineage among extraintestinal pathogenic E.

OmpC regulation differs between ST131 and non-ST131 Escherichia coli clinical isolates and involves differential expression of the small RNA MicC [PDF]

Journal of Antimicrobial Chemotherapy, 2020
Abstract Background Virulence genes and the expression of resistance mechanisms undoubtedly play a role in the successful spread of the pandemic clone Escherichia coli ST131. Porin down-regulation is a chromosomal mechanism associated with antibiotic resistance.

Molecular epidemiology and virulence of Escherichia coli O16:H5-ST131: Comparison with H30 and H30-Rx subclones of O25b:H4-ST131

International Journal of Medical Microbiology, 2014
The present study was carried out to evaluate the prevalence of the clonal subgroup O16:H5-ST131 and the H30 and H30-Rx subclones among E. coli isolates causing extraintestinal infections and to know their virulence potential. The ST131 clonal group accounted for 490 (16%) of the 2995 isolates obtained from clinical samples in five Spanish hospitals ...

Escherichia coli ST131 producing CTX-M-15 in Australia [PDF]

Journal of Antimicrobial Chemotherapy, 2010
Sir, Escherichia coli clonal group ST131 has been reported from many parts of the world and is frequently associated with production of CTX-M-type extended-spectrum β-lactamase (ESBL), in particular CTX-M-15.1,2 Clonal group ST131 may be associated with other β-lactamases or may be resistant to fluoroquinolones; some isolates may be cephalosporin ...

Escherichia coli ST131 Associated with Increased Mortality in Bloodstream Infections from Urinary Tract Source

Journal of Clinical Microbiology, 2023
Escherichia coli sequence type 131 (ST131) is a globally dominant multidrug-resistant clone, although its clinical impact on patients with bloodstream infection (BSI) is incompletely understood.

Evaluation of presence of clone ST131 and biofilm formation in ESBL producing and non-producing Escherichia coli strains

Molecular Biology Reports, 2023
Objective Escherichia coli ST131 is a pandemic clone associated with multidrug resistance, starting with beta-lactamase production and fluoroquinolone resistance in the first place, leading to significant systemic infections.

The Molecular Characterization and Risk Factors of ST131 and Non-ST131 Escherichia coli in Healthy Fecal Carriers in Tehran, Iran

Jundishapur Journal of Microbiology, 2022
Background: Commensal extended-spectrum β-lactamase (ESBL) producing Escherichia coli isolates in the gut can be the reservoir of virulence factors and resistance genes. Objectives: We investigated the molecular feature, risk factors, and quinolone/fluoroquinolone (Q/FQ) resistance in sequence type 131 (ST131) and non-ST131: ESBL-producing E. coli (EPE)

Different Factors Associated with CTX-M-Producing ST131 and Non-ST131 Escherichia coli Clinical Isolates

PLoS ONE, 2013
To determine factors associated with CTX-M-producing ST131 Escherichia coli which is the worldwide predominant lineage among CTX-M-producing E. coli isolates.Consecutive inpatients with a clinical sample positive for CTX-M-producing E. coli and considered as cases in a previous 8-month (2008-2009) case-control study performed in ten university ...

Distinct genealogies for plasmids and chromosome [PDF]

, 2014
An earlier perspective on the diversity of conjugative elements in microbes [1] attempted to provide a broad audience with an introductory overview of the arcane biology of mobile genetic elements and their terminologies. It might well have been entitled
