Genotypic Characterization of Virulence Factors in Extended-Spectrum Beta-Lactamase (ESBL)-Producing <i>Escherichia coli</i> Strains from Chickens in Hungary.

ABSTRACT: Background: The increasing attention on extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli strains isolated from poultry flocks stems from concerns about their virulence potential and zoonotic risk. Of particular significance is the identification of extraintestinal pathogenic E. coli (ExPEC) pathotypes in poultry, as these strains pose not only animal health concerns but also serious threats to food safety and public health. Mapping the genetic background of pathogenicity and antimicrobial resistance is essential for risk assessment and the development of effective control strategies. Methods: A total of 87 E. coli isolates were isolated from tracheal and cloacal swab samples collected from healthy chickens between 2022 and 2023. Whole-ge
