Genomic and phenotypic description of the newly isolated human species Collinsella bouchesdurhonensis sp. nov

Abstract

Using culturomics, a recently developed strategy based on diversified culture conditions for the isolation of previously uncultured bacteria, we isolated strain Marseille-P3296^T from a fecal sample of a healthy pygmy female. A multiphasic approach, taxono-genomics, was used to describe the major characteristics of this anaerobic and gram-positive bacillus that is unable to sporulate and is not motile. The genome of this bacterium is 1,878,572 bp-long with a 57.94 mol% G + C content. On the basis of these characteristics and after comparison with its closest phylogenetic neighbors, we are confident that strain Marseille-P3296^T (=CCUG 70328 = CSUR P3296) is the type strain of a novel species for which we propose the name Collinsella bouchesdurhonensis sp. nov.
