초록
Listeriosis is one of serious foodborne disease caused mainly by consumption of food contaminated with Listeria monocytogenes. In this study, we isolated L. monocytogenes strain IJPL9-1 from pork in Korea and conducted whole-genome sequencing (WGS). WGS data revealed a single chromosome of 2,913,085 bp. The strain was identified as sequence type (ST) 224, clonal complex (CC) 224, lineage I, and sub-lineage (SL) 6178 based on multilocus sequence typing (MLST) and core genome MLST (cgMLST). The average nucleotide identity was 95.15% with the reference genome EGD-e and 99.99% with FSCNU_000110, the outbreak strain in Korea in 2018. The serogroup was determined to be IIb, and the presence of antimicrobial resistance genes fosX, vga(G), mprF, norB, and sul was determined.
