Akkermansia
Scientific classification
Domain: Bacteria
Phylum: Verrucomicrobia
Class: Verrucomicrobiae
Order: Verrucomicrobiales
Family: Verrucomicrobiaceae
Genus: Akkermansia
Type species
A. muciniphila

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

Etymology

The name Akkermansia derives from:
New Latin feminine gender noun Akkermansia, named after Antoon DL Akkermans (28 October 1940 – 21 August 2006),[3] a Dutch microbiologist recognized for his contribution to microbial ecology.[4]

Species

The genus contains a single species,[4] namely A. muciniphila ( Derrien et al. 2004, (Type species of the genus).; New Latin neuter gender noun mucinum, mucin; New Latin adjective philus from Greek adjective philos (φίλος) meaning friend, loving; New Latin feminine gender adjective muciniphila, mucin-loving.)[5]

Description of Akkermansia gen. nov.

Akkermansia (Ak.ker.man'si.a. N.L. fem. n. Akkermansia derived from Antoon Akkermans, a Dutch microbiologist recognized for his contribution to microbial ecology). Cells are oval-shaped, non-motile and stain Gram-negative. Strictly anaerobic. Chemo-organotrophic. Mucolytic in pure culture.[2]:1474

Human metabolism

Akkermansia muciniphila, the only currently known species within genus Akkermansia, can reside in the human intestinal tract and is currently being studied for its effects on human metabolism. Recently performed studies in rodents have indicated that Akkermansia muciniphila in the intestinal tract may mediate obesity, diabetes, and inflammation.[6][7][8][9]

Mice that received microbiota from a lard-fed donor showed increased adiposity and inflammation, together with a significant increase in Lactobacillus, compared to mice that received microbiota from a fish-oil-fed donor. Therefore, these data do not provide evidence for a role of Lactobacillus in reducing inflammation. However, we found that the enrichment of Akkermansia co-occurred with partial protection against adiposity and inflammation in mice transplanted with fish-oil microbiota and fed a lard diet, highlighting Akkermansia as a potential mediator of the improved inflammatory and metabolic phenotype of mice fed fish oil.
