'''''Alistipes''''' is a Gram-negative genus of rod-shaped anaerobic bacteria in the phylum Bacteroidota.<ref name="main" /> When members of this genus colonize the human gastrointestinal (GI) tract, they provide protective effects against colitis (intestinal inflammation), and cirrhosis (liver fibrosis).{{citation needed|date=May 2025}} However, this genus can also cause dysbiosis by contributing to anxiety, chronic fatigue syndrome, depression, and hypertension.<ref>{{cite journal | vauthors = Parker BJ, Wearsch PA, Veloo AC, Rodriguez-Palacios A | title = The Genus ''Alistipes'': Gut Bacteria With Emerging Implications to Inflammation, Cancer, and Mental Health | journal = Frontiers in Immunology | volume = 11 | article-number = 906 | date = 2020 | pmid = 32582143 | pmc = 7296073 | doi = 10.3389/fimmu.2020.00906 | doi-access = free }}</ref> Showcasing priority effects in microbiome assembly, when infant GI tracts have bacteria of the species ''Staphylococcus'' but not the species ''Faecalibacterium'', ''Alistipes'' species become less capable of colonization.<ref>{{cite journal | vauthors = Debray R, Herbert RA, Jaffe AL, Crits-Christoph A, Power ME, Koskella B | title = Priority effects in microbiome assembly | journal = Nature Reviews.
