mcr-Positive Escherichia coli ST131-H22 from Poultry in Brazil [PDF]

open access: yesEmerging Infectious Diseases, 2020
Escherichia coli sequence type (ST) 131 is of concern because it can acquire antimicrobial resistance and cause extraintestinal infections. E. coli ST131-H22 sublineage appears capable of being transmitted to humans through poultry. We report on multidrug-resistant ST131-H22 poultry isolates in Brazil closely related to international human and poultry ...

Emergence of the New KPC-49 Variant Conferring an ESBL Phenotype with Resistance to Ceftazidime-Avibactam in the ST131-H30R1 Escherichia coli High-Risk Clone

open access: yesPathogens, 2021
We report the emergence of an isolate belonging to the sequence type (ST)131-Escherichia coli high-risk clone with ceftazidime-avibactam resistance recovered from a patient with bacteremia in 2019.

High Rates of Antimicrobial Resistance and Emergence of High‐Risk Clones in Community‐Acquired Uropathogenic Escherichia coli

open access: yesMicrobiologyOpen, Volume 14, Issue 5, October 2025.
A total of 98 E. coli isolates from community‐acquired UTIs were analyzed, revealing high resistance rates to trimethoprim‐sulfamethoxazole and fluoroquinolones. Phylogenetic group B2 was the most prevalent and associated with increased virulence, while ST1193 emerged as the dominant MDR clone.

Characteristics of Escherichia coli sequence type 131 isolates that produce extended-spectrum β-lactamases: global distribution of the H30-Rx sublineage [PDF]

open access: yes, 2014
We designed a study to describe the characteristics of sequence type 131 (ST131) lineages, including the H30-Rx sublineage, among a global collection of extended-spectrum β-lactamase (ESBL)-producing Escherichia coli isolates from 9 countries collected ...

The cnf1 gene is associated with an expanding Escherichia coli ST131 H30Rx/C2 subclade and confers a competitive advantage for gut colonization

open access: yesGut microbes, 2022
Epidemiological projections point to acquisition of ever-expanding multidrug resistance (MDR) by Escherichia coli, a commensal of the digestive tract and a source of urinary tract pathogens. Bioinformatics analyses of a large collection of E.

Molecular Characterisation of Escherichia coli Collected From an Urban River in Johannesburg, South Africa

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 5, October 2025.
Escherichia coli isolates from the Jukskei River in Johannesburg, South Africa, are genetically diverse, indicating multiple contamination sources and potential cross‐environmental transmission between the river, humans and livestock. Moreover, the presence of pathogenic E.

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

open access: yesJournal of Biomedical Sciences, 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

The revolving door between hospital and community: extended-spectrum beta-lactamase-producing Escherichia coli in Dublin. [PDF]

open access: yes, 2012
BACKGROUND: Escherichia coli that produce extended-spectrum beta-lactamases (ESBLs) are an increasing cause of healthcare-associated infection, and community healthcare facilities may be a reservoir for important epidemic clones.

Colistin-Resistant mcr-1-Positive Escherichia coli ST131-H22 Carrying blaCTX–M–15 and qnrB19 in Agricultural Soil

open access: yesFrontiers in Microbiology, 2021
The pandemic Escherichia coli sequence type 131 (ST131) carrying plasmid-mediated colistin resistance mcr genes has emerged worldwide causing extraintestinal infections, with lineages belonging to three major clades (A, B, and C).

Occurrence and spread of carbapenemase‐producing Enterobacterales (CPE) in the food chain in the EU/EFTA. Part 1: 2025 update

open access: yesEFSA Journal, Volume 23, Issue 4, April 2025.
Abstract Carbapenemase‐producing Enterobacterales (CPE) have been reported in the food chain in 14 out of 30 EU/EFTA countries. Commonly reported genes are blaVIM‐1, blaOXA‐48 and blaOXA‐181, followed by blaNDM‐5 and blaIMI‐1. Escherichia coli, target of most of the studies, Enterobacter cloacae complex, Klebsiella pneumoniae complex and Salmonella ...
