Molecular epidemiology of pESI-carrying <i>Salmonella</i> Infantis in Korea: insights from a one health framework.

ABSTRACT: The emergence and global dissemination of Salmonella Infantis carrying the pESI megaplasmid is a growing public health concern owing to its association with multidrug resistance (MDR), enhanced virulence, and increased environmental adaptability. This study investigated the molecular epidemiology and transmission dynamics of pESI-carrying S. Infantis in the poultry production chain and human clinical cases in Korea. A total of 295 Salmonella isolates were collected from poultry sources (farms, slaughterhouses, and retail meats) in 2023, of which 219 (74.2%) were identified as S. Infantis. Additionally, 22 human-origin S. Infantis isolates collected between 2016 and 2023 were included in this study. Among these 241 S. Infantis isolates, 218 from pou
