Strain Marseille-P4119T was isolated from a faecal sample of a healthy 32-year-old faecal transplant donor. The bacterium was anaerobic, Gram-negative, rod-shaped, non-motile and did not produce spores. We studied its phenotypic characteristics and sequenced its whole genome. The major fatty acids were C15:0 anteiso and C15:0 iso. The final genome assembly was 3912 650 bp long with a 44.4 mol% G + C content, 3094 protein-coding genes and 74 RNA genes. Strain Marseille-P4119T exhibited a 97.10% 16S rRNA sequence identity and a 29.0% dDDH with Prevotella stercorea CB35T, OrthoANI values ranged from 68.5% with Prevotella enoeca to 77.4% with Prevotella stercorea, the phylogenetically closest bacterial species with standing in nomenclature. Based on the phylogenetic, phenotypic and genomic analyses, we propose the creation of the novel species Prevotella merdae sp. nov. The type strain is Marseille-P4119T ( = CSUR P4119T = CECT 9566T).
