This review provides a comprehensive overview of the multifaceted mechanisms employed by <em>L. monocytogenes</em> to overcome gastrointestinal hurdles and interact with the host's microbiota, facing chemical and physical barriers such as saliva, stomach acidity, bile salts and mechanical clearance. Proposed evasion strategies will be highlighted, exploring the bacteriocins produced by <em>L. monocytogenes</em>, such as the well-described bacteriocin Listeriolysin S (LLS), a bacteriocin that inhibits inflammogenic species – Lmo2776, and a phage tail-like bacteriocin, monocin. The competitive dynamic interactions within the gut microbiota, as well as the modulation of microbiota composition and immune responses, will also be explored. Finally, the adhesion and invasion of the intestinal epithelium by <em>L. monocytogenes</em> is described, exploring the mechanism of pathogenesis, biofilm and aggregation capacities and other virulence factors. Unlike previous reviews that may focus on individual aspects of <em>L. monocytogenes</em> pathogenicity, this review offers a holistic perspective on the bacterium's ability to persist and cause infection, integrating information about survival strategies, including bacteriocin production, immune modulation, and virulence factors. By connecting recent findings on microbial interactions and infection dynamics, this review incorporates recent developments in the field and connects various lines of research that explore both host and microbial factors influencing infection outcomes.</div></div>","PeriodicalId":18564,"journal":{"name":"Microbiological research","volume":"297 ","pages":"Article 128187"},"PeriodicalIF":6.1,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143863633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, responses of these microbiotas to different extreme environments remain poorly understood. White-lipped deer (<em>Przewalskium albirostris</em>), a native endangered species in the QTP, serves as an ideal model to study how gut microbiotas adapt to season and human disturbances. Here, a multi-omics integrated analysis of 16S rRNA, metagenomics, and untargeted metabolomics was performed to investigate the composition, function, and metabolic characteristics of gut microbiota in White-lipped deer across different seasons and living environments. Our results revealed that extreme winter environment dominated the composition, function, and metabolism of gut microbiota in white-lipped deer. The white-lipped deer exhibited an enriched gut microbiota associated with producing short-chain fatty acids in winter, with core feature genera including norank_o_Rhodospirillales, <em>Rikenellaceae_RC9_gut_group</em>, and unclassified_c_Clostridia.

Pathways associated with carbohydrate metabolism, amino acid metabolism, and immune regulation showed enrichment in winter group as an adaptation to the cold and food scarcity. Among these, <em>Rikenellaceae_RC9_gut_group</em> and unclassified_c_Clostridia contributed significantly to these metabolic pathways. The gut microbiota of white-lipped deer exhibited enrichment in pathways related to intestinal inflammation and enhanced immune regulation to alleviate the stress of captivity.

The results revealed significant differences in bacterial α- and β-diversity, with novel microbial taxa and a complex microbial network emerging postinfection.

Since outer membrane vesicles (OMVs) of Gram-negative bacteria may contribute to antimicrobial resistance, our present study was aimed at investigating OMVs produced by the first two carbapenem- and tetracycline-resistant <em>A. baumannii</em> isolates in Europe.
