Virulence Gene Profiles of Extended-Spectrum β-Lactamase (ESBL)-Producing <i>Escherichia coli</i> Isolated from Turkeys in Hungary: A Whole-Genome Sequencing Study.

ABSTRACT: Background:Escherichia coli strains associated with poultry are increasingly recognized as reservoirs of both virulence and resistance genes, posing significant zoonotic risks throughout the food production chain. However, the genotypic architecture and pathogenic potential of isolates from large-scale turkey farms remain under characterized, particularly in the context of extended-spectrum β-lactamase (ESBL) production. Methods: A total of 160 ESBL-producing E. coli isolates were collected from healthy turkeys on intensive Hungarian farms. Whole genome sequencing (WGS) was performed to characterize virulence factors. Functional annotation included screening for fimbrial adhesins, iron acquisition systems, secretion pathways, and autotransporter toxins, using Vi
