In South Korea, listeriosis had only been reported sporadically among hospitalized patients until the first foodborne outbreak occurred in 2018. In this study, a <jats:italic>L. monocytogenes<\/jats:italic> strain responsible for this outbreak (FSCNU0110) was characterized via whole genome sequencing and compared with publicly available <jats:italic>L. monocytogenes<\/jats:italic> genomes of the same clonal complex (CC). Strain FSCNU0110 belonged to multilocus sequence typing (MLST)-based sequence type 224 and CC224, and core genome MLST-based sublineage 6,178. The strain harbored tetracycline resistance gene <jats:italic>tetM<\/jats:italic>, four other antibiotic resistance genes, and 64 virulence genes, including <jats:italic>Listeria<\/jats:italic> pathogenicity island 1 (LIPI-1) and LIPI-3. Interestingly, <jats:italic>llsX<\/jats:italic> in LIPI-3 exhibited a characteristic SNP (deletion of A in position 4, resulting in a premature stop codon) that was missing among all CC224 strains isolated overseas but was conserved among those from South Korea. In addition, the <jats:italic>tetM<\/jats:italic> gene was also detected only in a subset of CC224 strains from South Korea. These findings will provide an essential basis for assessing the characteristics of CC224 strains in South Korea that have shown a potential to cause listeriosis outbreaks.<\/jats:p>","DOI":"10.3389\/fmicb.2023.1182090","type":"journal-article","created":{"date-parts":[[2023,6,2]],"date-time":"2023-06-02T13:20:51Z","timestamp":1685712051000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":13,"title":["Whole-genome sequencing of Listeria monocytogenes isolated from the first listeriosis foodborne outbreak in South Korea"],"prefix":"10.3389","volume":"14","author":[{"given":"Seung Hun","family":"Lee","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sangmi","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang Hun","family":"Park","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ok Kyung","family":"Koo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,6,2]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"5401","DOI":"10.1073\/pnas.1501775112","article-title":"Cryo-EM structure of the tetracycline resistance protein TetM in complex with a translating ribosome at 3.9-\u00c5 resolution","volume":"112","author":"Arenz","year":"2015","journal-title":"Proc.
