Antimicrobial Resistance and Virulence Factors Assessment in Escherichia coli Isolated from Swine in Italy from 2017 to 2021.

ABSTRACT: Prudent antibiotic use in pigs is critical to ensuring animal health and preventing the development of critical resistance. We evaluated the antimicrobial resistance (AMR) pattern in commensal and enterotoxigenic Escherichia&nbsp;coli (ETEC) isolates obtained in 2017-2021 from pigs suffering from enteric disorders. Overall, the selected 826 E. coli isolates showed the highest level of resistance to ampicillin (95.9%), tetracycline (89.7%), cefazolin (79.3%), and trimethoprim/sulfamethoxazole (74.8%). The resistance rates of the isolates to ampicillin increased (p < 0.05), reaching 99.2% of resistant strains in 2021. Regarding isolates harboring virulence genes, ETEC F18+ were significantly more resistant to florfenicol, gentamicin, kanamycin, and trimethoprim/su
