Using microbial culturomics, we were able to isolate strain Marseille-P3078 from a stool sample of a healthy 50-year-old Saudi Arabian woman. To this end, we used taxonogenomics that combines phenotypic, biochemical and genomic analyses, to describe this bacterium. Cells from strain Marseille-P3078 are anaerobic and Gram-negative rods that are motile and unable to sporulate. Its genome size is 3,377,914-bp-long with a 66.33 mol% G + C content. Based on its phenotypic and genomic features, including a 94.6% 16S rRNA similarity with Paraeggerthella hongkongensis strain JCM 14552, its closest phylogenetic neighbor withstanding in nomenclature, we propose that strain Marseille-P3078T (= CSUR P3078 = DSM 104007) is the representative strain of a new genus for which we propose the name Arabiibacter massiliensis gen. nov., sp. nov.
利用微生物培养组学，我们从一名 50 岁沙特阿拉伯健康女性的粪便样本中分离出了一株马赛 P3078 菌株。为此，我们采用了分类基因组学，将表型、生化和基因组分析相结合，来描述这种细菌。马赛 P3078 菌株的细胞为厌氧革兰氏阴性棒状，能运动但不能形成孢子。其基因组大小为 3,377,914-bp，G+C 含量为 66.33 mol%。基于其表型和基因组特征，包括与 Paraeggerthella hongkongensis 菌株 JCM 14552 的 16S rRNA 相似性为 94.6%，这是其在命名上最接近的系统发育邻居，我们建议将马赛 P3078T 株（= CSUR P3078 = DSM 104007）作为一个新属的代表菌株，我们提议将其命名为 Arabiibacter massiliensis gen. nov.，sp. nov.。
