Prevalence and characterization of extended-spectrum β-lactamase-producing and isolated from raw vegetables retailed in Southern Thailand.

Background: The increasing prevalence of broad-spectrum ampicillin-resistant and third-generation cephalosporin-resistant , particularly and , has become a global concern, with its clinical impacts on both human and veterinary medicine. This study examined the prevalence, antimicrobial susceptibility, and molecular genetic features of extended-spectrum β-lactamase (ESBL)-producing and isolates from 10 types of raw vegetables.

Methods: In total, 305 samples were collected from 9 markets in Nakhon Si Thammarat, Thailand, in 2020.
