Antimicrobial susceptibility testing was performed using the VITEK-2 system. Genomic analysis included determination of sequence types (STs), clonal complexes (CCs), genomic characterization using multi-locus sequence typing (MLST), core-genome MLST (cgMLST), antimicrobial resistance (AMR) determinants and virulence gene profiles.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results.<\/jats:bold>\n                    Seven isolates (S2\u2013S8) were ST2 and belonged to CC2, whereas S1 and S9 were classified as ST3 and ST308 and belonged to CC3 and CC1, respectively. Phenotypic susceptibility profiles were correlated with genotypic findings, with a conserved resistome dominated by\n                    <jats:italic>fosX<\/jats:italic>\n                    (fosfomycin resistance) and\n                    <jats:italic>vga(G<\/jats:italic>\n                    ) (lincosamide resistance). All isolates harboured conserved core virulence genes associated with stress response, quorum sensing, nutrient regulation, host cell invasion and intercellular survival. The cgMLST analysis demonstrated \u226599.5% genetic similarity among ST2\/CC2 isolates, which clustered together and were genetically distinct from older local isolates (S1, S9) and international reference strains.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusion.<\/jats:bold>\n                    This first WGS-based genomic characterization of\n                    <jats:italic>L. monocytogenes<\/jats:italic>\n                    in Kuwait demonstrates the repeated detection of ST2\/CC2 across multiple maternal and neonatal cases over several years. These findings provide baseline genomic data and highlight the need for integrated, expanded genomic surveillance linking clinical, food and environmental isolates to improve source attribution, early detection and public health interventions for listeriosis.\n                  <\/jats:p>","DOI":"10.1099\/jmm.0.002181","type":"journal-article","created":{"date-parts":[[2026,6,29]],"date-time":"2026-06-29T16:15:52Z","timestamp":1782749752000},"source":"Crossref","is-referenced-by-count":0,"title":["Whole-genome sequencing of Listeria monocytogenes from maternal and neonatal clinical isolates in Kuwait"],"prefix":"10.1099","volume":"75","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3496-2788","authenticated-orcid":false,"given":"Ola H.","family":"Moghnia","sequence":"first","affiliation":[{"name":"Department of Microbiology, College of Medicine, Kuwait University, Kuwait City, Kuwait"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aisha M.","family":"Al-Haqqan","sequence":"additional","affiliation":[{"name":"Microbiology Laboratory, Maternity Hospital, Ministry of Health, Kuwait City, Kuwait"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hessah S.","family":"Al-Otaibi","sequence":"additional","affiliation":[{"name":"Microbiology Laboratory, Maternity Hospital, Ministry of Health, Kuwait City, Kuwait"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdallah","family":"B.
