akkermansia akkermansia akkermansia is a genus in the phylum verrucomicrobiota (bacteria). the genus was first proposed by derrien et al. (2004), with the type species akkermansia muciniphila (gen. nov., sp. nov). akkermansia scientific classification domain: bacteria phylum: verrucomicrobiota class: verrucomicrobiae order: verrucomicrobiales family: akkermansiaceae genus: akkermansiaderrien et al. 2004 type species akkermansia muciniphiladerrien et al. 2004 species a. glycaniphila "ca. a. intestinavium" "ca. a. intestinigallinarum" a. muciniphila etymology the name akkermansia derives from:neo-latin feminine gender noun akkermansia, named after anton dirk louis akkermans (28 october 1940 – 21 august 2006), a dutch microbiologist recognized for his contribution to microbial ecology. until 2016 the genus contained a single known species, namely a. muciniphila (derrien et al. 2004, (type species of the genus).; 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). however, de vos et al. isolated a novel species in the feces of a reticulated python, akkermansia glycaniphila. 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 organism. chemo-organotrophic. mucolytic in pure culture.: 1474 phylogeny the currently accepted taxonomy is based on the list of prokaryotic names with standing in nomenclature (lpsn) and national center for biotechnology information (ncbi) 16s rrna based ltp_01_2022 120 marker proteins based gtdb 07-rs207 a. muciniphila a. glycaniphila a. muciniphila derrien et al. 2004 a. glycaniphila ouwerkerk et al. 2016 "ca. a. intestinavium" gilroy et al. 2021 "ca. a. intestinigallinarum" gilroy et al. 2021 human metabolism akkermansia muciniphila can reside in the human intestinal tract and is currently being studied for its effects on human metabolism and health.
