Microbiol."],"abstract":"<jats:p><jats:italic>Listeria monocytogenes<\/jats:italic> is a foodborne pathogen that causes listeriosis, a disease with a mortality rate of 20\u202f~\u202f30%. This bacterium enters the human body through contaminated food or ingredients and encounters primary innate defense systems, including gastric acid, bile salts, and gut microbiota. These systems play a critical role in preventing pathogen colonization and infection. However, interactions with pathogens can also alter the gut microbiota profile. This study aimed to investigate the host\u2019s defense mechanisms against <jats:italic>L. monocytogenes<\/jats:italic> and the changes in the gut microbiota profile following infection. <jats:italic>L. monocytogenes<\/jats:italic> ATCC 7644 showed the greatest reduction (7.6 log CFU), followed by ATCC 19111 (5.71 log), F2365 (5.02 log), ATCC 19113 (3.96 log), and NCCP 14714 (3.38 log), while the pooled cocktail exhibited a 3.49 log CFU reduction. Notably, the clinical isolates NCCP 14714 and F2365 exhibited greater resistance to the simulated digestive process compared to the food isolate ATCC 7644. <jats:italic>L. monocytogenes<\/jats:italic> infection induced notable shifts in specific bacterial groups, including <jats:italic>Bacteroides<\/jats:italic>, <jats:italic>Bifidobacterium<\/jats:italic>, and the <jats:italic>Mediterraneibacter gnavus<\/jats:italic> group, as well as an increase in ethanol levels. These alterations may contribute to gut barrier disruption and the upregulation of immune responses, ultimately promoting the pathogenesis of <jats:italic>L. monocytogenes<\/jats:italic> infection. The findings from this study provide valuable insights into the interaction between <jats:italic>L. monocytogenes<\/jats:italic> and the human gut microbiota, offering a comparative reference for the interpretation of future research.<\/jats:p>","DOI":"10.3389\/fmicb.2025.1616720","type":"journal-article","created":{"date-parts":[[2025,7,23]],"date-time":"2025-07-23T05:37:03Z","timestamp":1753249023000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Exploring the fate of Listeria monocytogenes in an in vitro digestion and fecal fermentation model: insights into survival during digestion and interaction with gut microbiota"],"prefix":"10.3389","volume":"16","author":[{"given":"Dong Woo","family":"Kim","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saloni","family":"Singh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ui In","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"So Hyeon","family":"An","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyeon Ji","family":"Je","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong Young","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eun Ju","family":"Yun","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":[[2025,7,23]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"672353","DOI":"10.3389\/fimmu.2021.672353","article-title":"Aging-induced dysbiosis of gut microbiota as a risk factor for increased Listeria monocytogenes infection","volume":"12","author":"Alam","year":"2021","journal-title":"Front.
