High prevalence of multidrug-resistant <i>Salmonella enterica</i> in Thailand food markets: insights from complete genome and phenotypic characterization of ESBL-producing strains.

ABSTRACT: Salmonella contamination in the food chain is a common root of foodborne outbreaks. The transmission of antimicrobial resistance among Salmonella and food bacteria raises global public health concern. As a major food exporter and travel hub in Southeast Asia, Thailand is particularly susceptible. To better understand the circulating Salmonella, we characterized 74 non-typhoidal Salmonella isolates previously obtained from Thailand food markets. Whole genome sequencing, drug susceptibility testing, and host invasion efficiency assays were performed. The most prevalent serotype was Salmonella serotype Rissen (32.43%) followed by Derby (12.16%). Fifty-two isolates were multidrug-resistant (MDR), with their primary resistance pattern being ampicillin, strepto
