In vitro Relative Fitness, in vivo Intestinal Colonization and Genomic Differences of Escherichia coli of ST131 Carrying blaCTX–M–15

Frontiers in Microbiology, 2022
IntroductionExtended-spectrum beta-lactamase (ESBL) producing Escherichia coli have become prevalent worldwide, with E. coli of sequence type 131 (ST131) as the dominant genotype. E.

Possible step-up in prevalence for Escherichia coli ST131 from fecal to clinical isolates: inferred virulence potential comparative studies within phylogenetic group B2

Journal of Biomedical Science, 2022
Background Escherichia coli sequence type (ST)131 is an important urinary tract pathogen, and is responsible for considerable healthcare-associated problems and costs worldwide. A better understanding of the factors that contribute to its rapid worldwide

Clonal diversity, virulence genes content and subclone status of Escherichia coli sequence type 131: comparative analysis of E. coli ST131 and non-ST131 isolates from Iran

BMC Microbiology, 2019
Background The Escherichia coli sequence type 131 (ST131) is a well established clone causing significant extraintestinal infections worldwide. However, no studies have been reported the phenotypic and molecular traits of ST131 isolates in comparison to ...

Phylogeny, Resistome, and Virulome of Escherichia coli Causing Biliary Tract Infections [PDF]

, 2019
Escherichia coli is the most frequent Gram-negative bacilli involved in intra-abdominal infections. However, despite high mortality rates associated with biliary tract infections due to E. coli, there is no study focusing on this pathogen. In this study,

Characterization of Globally Spread Escherichia coli ST131 Isolates (1991 to 2010) [PDF]

Antimicrobial Agents and Chemotherapy, 2012
ABSTRACT The characterization of a broad representative sample of ST131 Escherichia coli isolates from different origins and settings (1991 to 2010) revealed that this clonal group has likely diversified recently and that the expansion of particular variants has probably been favored by the capture of ...

Cephem Potentiation by Inactivation of Nonessential Genes Involved in Cell Wall Biogenesis of ß-Lactamase-Producing Escherichia coli [PDF]

, 2017
Reversal of antimicrobial resistance is an appealing and largely unexplored strategy in drug discovery. The objective of this study was to identify potential targets for “helper” drugs reversing cephem resistance in Escherichia coli strains producing β ...

Escherichia coli O25b-ST131: a pandemic, multiresistant, community-associated strain [PDF]

Journal of Antimicrobial Chemotherapy, 2010
Escherichia coli sequence type 131 (ST131) is a worldwide pandemic clone, causing predominantly community-onset antimicrobial-resistant infection. Its pandemic spread was identified in 2008 by utilizing multilocus sequence typing (MLST) of CTX-M-15 extended-spectrum β-lactamase-producing E. coli from three continents.

Comparative Metabolic Characterization of Extraintestinal Pathogenic Escherichia coli Blood Isolates from Saudi Arabia

Journal of Tropical Medicine, 2022
Background. The prevalence of bloodstream infections caused by extraintestinal pathogenic Escherichia coli (ExPEC) has increased substantially. E. coli ST131 is one of the dominant ExPEC clones among E. coli bacteremia population.
