RANK: Species

TAXONOMY: Bacteroidetes/Chlorobi group -> Bacteroidetes -> Bacteroidia -> Bacteroidales -> Rikenellaceae -> Alistipes -> Alistipes shahii

OVERVIEW:

Two groups of previously unknown Gram-negative, strictly anaerobic, pigment-producing, rod-shaped bacteria, which phenotypically and phylogenetically displayed a close association with the recently described species Alistipes finegoldii, were characterized using phenotypic and molecular taxonomic methods. A 16S rRNA gene sequence divergence of approximately 3 % between the two unknown bacteria and A. finegoldii, as well as distinguishable biochemical characteristics, demonstrates that these organisms are genotypically and phenotypically distinct and that each group represents a previously unknown subline within the genus Alistipes. Chromosomal DNA–DNA reassociation studies further confirmed the separateness of the unidentified bacteria and A. finegoldii. On the basis of the phenotypic and phylogenetic findings, two novel species, Alistipes onderdonkii sp. nov. and Alistipes shahii sp. nov., are proposed. The type strains of A. onderdonkii and A. shahii are WAL 8169T (=CCUG 48946T=ATCC BAA-1178T) and WAL 8301T (=CCUG 48947T=ATCC BAA-1179T), respectively; their DNA G+C contents are 58 and 56 mol%, respectively.

This species has been identified as a resident in the human gastrointestinal tract based on the phylogenetic framework of its small subunit ribosomal RNA gene sequences.[PMC 4262072]

COGEM
COGEM released a comprehensive database of pathogenicity assessment of around 2575 bacterial species in 2011. The database ranks the pathogenicity of species on a scale of 1 to 4. Alistipes shahii ranks 2 on this scale: Species that can cause diseases in humans or animals, which are unlikely to spread in the human population and for which an adequate prophylaxis or therapy exists
Identified as a 'core species' of the human gut microbiome. [PMID: 23222524]
