Alistipes
Genus of bacteria
From Wikipedia, the free encyclopedia
Alistipes is a Gram-negative genus of rod-shaped anaerobic bacteria in the phylum Bacteroidota.[2] 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] However, this genus can also cause dysbiosis by contributing to anxiety, chronic fatigue syndrome, depression, and hypertension.[3] 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.[4] Alistipes, typically benign in the gut, can sometimes trigger infections like intra-abdominal abscesses and bloodstream infections, emphasizing the fine line between symbiosis and disease. This underscores the significance of comprehending their impact on human health within microbial ecosystems.[5]
