Abstract

We compared 15 Salmonella Enteritidis isolates collected in South Korea in 2023: 11 from chickens and 4 from humans. All isolates belonged to ST11, and they were divided into two clusters, rST3888 and rST1425. All four human isolates were colistin-resistant, and mcr-1 was identified in three isolates.

Keywords: Colistin resistance; Salmonella Enteritidis; rMLST.
