class I integrons and gene cassettes in multidrug-resistant Escherichia coli isolates from humans and food-producing animals

Class I integrons have garnered significant attention due to pivotal roles in dissemination of antimicrobial resistance genes (ARGs), which impose risks to public health and food safety. Here, the prevalence and characteristics of class I integrons in Escherichia coli isolates derived from food-producing animals and human patients were assessed.
