A. putredinis (Weinberg et al. 1937) Rautio et al. 2003[1]
Alistipes is a
Gram-negativegenus of
rod-shapedanaerobicbacteria in the
phylumBacteroidota.[2] When members of this genus colonize the human
gastrointestinal (GI) tract, they provide protective effects against
colitis (intestinal inflammation),
autism, and
cirrhosis (liver fibrosis). 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]
Etymology
Alistipes is derived from the
Neo-Latin noun alistipes, meaning "the other stick", which is further derived from the
Latin adjective alius (other) and noun stipes (log/post).[2]
