Antimicrobial resistance and plasmid-associated virulence genes in <i>Salmonella</i> isolated from pigs, pork, and humans in border provinces of Thailand and neighboring countries.

ABSTRACT: In Southeast Asia, most antimicrobial resistance (AMR) data on Salmonella have been generated at the phenotypic level, while insights into the genetic characteristics of AMR and virulence genes remain limited. This study aimed to further characterize AMR Salmonella isolates carrying plasmid-associated virulence genes in Thailand and neighboring countries. A total of 366 Salmonella isolates were collected from pigs (n = 265), pork (n = 69), and humans (n = 32) across Thailand, Lao People's Democratic Republic, Cambodia, and Myanmar. Overall, 69.40% (n = 254/366) were multidrug resistant, including resistance to medically important antimicrobials tigecycline, azithromycin, colistin and ciprofloxacin. Whole genome sequencing analysis revealed t
