Distribution and expression of virulence genes (hlyA, sat) and genotyping of Escherichia coli O25b/ST131 by multi-locus variable number tandem repeat analysis in Tehran, Iran.

Acta Microbiologica et Immunologica Hungarica, 2022
Escherichia coli ST131 is a pandemic clone with high antibiotic resistance, and it is a major causative agent of urinary tract infection (UTI) and bloodstream infections.

Geographic containment and virulence‐resistance trade‐offs drive the evolution of hypervirulent Klebsiella pneumoniae

iMeta, Volume 4, Issue 5, October 2025.
The global emergence of hypervirulent, carbapenem‐resistant Klebsiella pneumoniae (hvCRKP) poses a paradox: why do such dangerous clones remain geographically confined? By analyzing over 2500 CC23 genomes across 90 years, we uncover a core evolutionary constraint—virulence and resistance rarely coexist without trade‐offs. Potent carbapenemases (blaKPC,

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

MicrobiologyOpen, 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.
