Noncontiguous finished genome sequence and description of Fusobacterium massiliense sp. nov. isolated from human duodenum

Abstract

The strain Marseille-P2749T (= CSUR P2749=DSM 103085) was isolated as part of culturomics study from a liquid duodenum sample from a French man. Bacterial cells were Gram-negative bacilli, fusiform shaped and non–spore forming, and they grew in microaerophilic and anaerobic atmosphere. Its genome is 1 809 169 bp long and contains 1646 protein-coding genes. The DNA G+C content was 27.33 mol%. This strain exhibited a 95.9% sequence similarity with Fusobacterium periodonticum, the phylogenetically closest species with standing in nomenclature. Strain Marseille-P2749T is suggested to be a novel species belonging to the genus Fusobacterium, for which the name Fusobacterium massiliense sp. nov. is proposed.
