Akkermansia is a genus in the phylum Verrucomicrobiota (Bacteria).[2] The genus was first proposed by Derrien et al. (2004), with the type species Akkermansia muciniphila (gen. nov., sp. nov).[1]

Species[2]

Until 2016 the genus contained a single known species, namely A. muciniphila.[2] In 2016, Akkermansia glycaniphila was isolated in the feces of a reticulated python.[3]

Etymology

edit

The name Akkermansia (Ak.ker.man'si.a.) derives from: Neo-Latin feminine gender noun Akkermansia, named after Anton Dirk Louis Akkermans (28 October 1940 – 21 August 2006),[4] a Dutch microbiologist recognized for his contribution to microbial ecology.[2] Neo-Latin neuter gender noun mucinum, mucin; Neo-Latin adjective philus from Greek adjective philos (φίλος) meaning friend, loving; Neo-Latin feminine gender adjective muciniphila, mucin-loving).[1]

Description

edit

Cells are oval-shaped, non-motile and stain Gram-negative. Strictly anaerobic organism. Chemo-organotrophic. Mucolytic in pure culture.[1]: 1474 

Phylogeny

edit

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)[2] and National Center for Biotechnology Information (NCBI)[5]

Human metabolism

edit

Akkermansia muciniphila can reside in the human intestinal tract and is currently being studied for its effects on human metabolism and health.[12] It could be of interest for the treatment of obesity and type 2 diabetes. Akkermansia has been shown to reverse high-fat diet-induced metabolic disorders in mice by increasing intestinal levels of endocannabinoids (e.g. 2-arachidonoylglycerol and 2-oleoylglycerol) and mucosal thickness.[13][14][15] Another study showed that Akkermansia muciniphil alleviates depression-like behavior by regulating gut microbiota and metabolites in a chronic stress mouse model.[16]
