Species of the Bacteroidales order are among the most abundant and stable bacterial members of the human gut microbiome, with diverse impacts on human health. We cultured and sequenced the genomes of 408 Bacteroidales isolates from healthy human donors representing nine genera and 35 species and performed comparative genomic, gene-specific, metabolomic, and horizontal gene transfer analyses. Families, genera, and species could be grouped based on many distinctive features. We also observed extensive DNA transfer between diverse families, allowing for shared traits and strain evolution. Inter- and intra-species diversity is also apparent in the metabolomic profiling studies. This highly characterized and diverse Bacteroidales culture collection with strain-resolved genomic and metabolomic analyses represents a valuable resource to facilitate informed selection of strains for microbiome reconstitution.

对大型人类肠道拟杆菌属 (Bacteroidales) 培养物保藏库的全面分析揭示了物种和菌株水平的多样性和进化



拟杆菌目 (Bacteroidales) 是人类肠道微生物组中最丰富和最稳定的细菌成员之一,对人类健康有多种影响。我们对来自健康人类供体的 408 个拟杆菌属分离株的基因组进行了培养和测序,这些分离株代表 9 个属和 35 个物种,并进行了比较基因组、基因特异性、代谢组学和水平基因转移分析。科、属和种可以根据许多独特的特征进行分组。我们还观察到不同家族之间的广泛 DNA 转移,允许共享性状和菌株进化。物种间和物种内的多样性在代谢组学分析研究中也很明显。这种高度表征和多样化的拟杆菌属培养物保藏品具有菌株分辨基因组和代谢组学分析,是促进微生物组重建菌株的明智选择的宝贵资源。
