Oral and parenteral treatment with a third-generation cephalosporin promotes the proliferation of diverse ESBL-producing Escherichia coli in the chicken intestinal tract

ABSTRACT The global rise of antimicrobial resistance is a major public health threat, with Escherichia coli facilitating the spread of extended-spectrum beta-lactamase (ESBL) genes like blaCTX-M, which confer resistance to third-generation cephalosporins (3GCs). This study examines the impact of 3GC...
