Clonal/subclonal changes and accumulation of CTX-M-type β-lactamase genes in fluoroquinolone-resistant Escherichia coli ST131 and ST1193 strains isolated during the past 12 years, Japan

Journal of Global Antimicrobial Resistance, 2021
: Objectives: Fluoroquinolone (FQ)- and third-generation cephalosporin-resistant Escherichia coli are increasing in Japan. In the early 2000s, the FQ-resistant E. coli clone ST131 increased in clinical settings worldwide. It frequently produces extended-

High Rates of Antimicrobial Resistance and Emergence of High-Risk Clones in Community-Acquired Uropathogenic Escherichia coli. [PDF]

Microbiologyopen
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.

Resistome and Virulome of Multi-Drug Resistant E. coli ST131 Isolated from Residents of Long-Term Care Facilities in the Northern Italian Region [PDF]

Diagnostics, 2022
Long-term care facilities (LTCFs) are important reservoirs of antimicrobial-resistant (AMR) bacteria which colonize patients transferred from the hospital, or they may emerge in the facility as a result of mutation or gene transfer. In the present study,

Using Ongoing Wildlife Surveillance Programs to Monitor Antibiotic Resistant Bacteria in the Environment. [PDF]

Environ Microbiol Rep
Screening of ESBL‐, pAmpC‐ and carbapenemase‐producing Escherichia coli among Swedish wildlife demonstrated a low occurrence of antibiotic resistance in wild animals. Only two ESBL/pAmpC‐producers were detected in red foxes originating from highly populated areas.

Commensal Fitness Advantage May Contribute to the Global Dissemination of Multidrug-Resistant Lineages of Bacteria—The Case of Uropathogenic E. coli

Pathogens, 2023
It is widely accepted that favorable fitness in commensal colonization is one of the prime facilitators of clonal dissemination in bacteria. The question arises as to what kind of fitness advantage may be wielded by uropathogenic strains of the two ...

Pandemic fluoroquinolone resistant Escherichia coli clone ST1193 emerged via simultaneous homologous recombinations in 11 gene loci

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Global growth in antibiotic resistance is a major social and health problem. The most common mechanism of high resistance to fluoroquinolones is the sequential acquisition of 3 mutations in 2 DNA topoisomerases, GyrA and ParC.
