While most microbiome research has focused on bacteria, the intestinal microbiota encompasses a diverse constellation of microorganisms, including viruses, fungi, archaea, and protists. Among these microbes, commensal protists have been particularly neglected, to the point that their status as true members of the microbiota remained contentious. However, findings over the past decade revealed that commensal protists, particularly those in the Parabasalia phylum (parabasalids), perform keystone roles within the intestinal ecosystem. Emerging evidence highlights how parabasalids dramatically impact host immunity, gut microbiome ecology, and host susceptibility to both infectious and inflammatory diseases. In this review, we discuss the recent discoveries of the varied and powerful roles of commensal parabasalids in the intestinal microbiota and outline the challenges and opportunities in this burgeoning new area of the microbiome field.</p>","PeriodicalId":23275,"journal":{"name":"Trends in Microbiology","volume":" ","pages":"603-618"},"PeriodicalIF":14.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143426335","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}

We examine the recent literature advancing such systems, including (i) in silico models establishing the theoretical basis for how cell-to-cell interactions can influence population level dynamics, (ii) in vitro models characterizing specific interbacterial interactions, (iii) organ-on-a-chip models revealing the physiologically relevant parameters, such as spatial structure and mechanical forces, that bacteria encounter within a host, and (iv) in vivo plant and animal models connecting the host responses to interbacterial interactions.
