Prevalence and genetic basis of extended-spectrum β-lactamase-producing <i>Escherichia coli</i> carriage in broiler farms in the United Arab Emirates.

ABSTRACT:

Background

Poultry production plays a vital role in ensuring food security and nutritional sustainability in the United Arab Emirates (UAE). However, the emergence and spread of antimicrobial-resistant bacteria in poultry farms present a growing public health concern in the region. To address this gap, this study investigated the prevalence and genetic basis of extended-spectrum β-lactamase (ESBL)-producing Gram-negative bacteria in cecal contents of chickens collected from two major poultry farms in Al Ain, UAE.

Methods

A total of 77 samples were collected over an eleven-month period, yielding 146 non-duplicate Gram-negative isolates, of which Escherichia coli was the most prevalent species (82.9%). All the isolates were tested phenotypically and genotypically by PCR
