Understanding how the human virome, and which of its constituents, contributes to health or disease states is reliant on obtaining comprehensive virome profiles. By combining DNA viromes from isolated virus-like particles (VLPs) and whole metagenomes from the same faecal sample of a small cohort of healthy individuals and patients with severe myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), we have obtained a more inclusive profile of the human intestinal DNA virome. Key features are the identification of a core virome comprising tailed phages of the class , and a greater diversity of DNA viruses including extracellular phages and integrated prophages. Using an in silico approach, we predicted interactions between members of the genus and unique viruses present in ME/CFS microbiomes. This study therefore provides a framework and rationale for studies of larger cohorts of patients to further investigate disease-associated interactions between the intestinal virome and the bacteriome.
了解人类病毒组及其组成部分如何影响健康或疾病状态,依赖于获得全面的病毒组谱。通过结合从小队列的健康个体和患有严重肌痛性脑脊髓炎/慢性疲劳综合征 (ME/CFS) 的患者的分离病毒样颗粒 (VLP) 的 DNA 病毒组和来自相同粪便样本的全宏基因组,我们获得了更全面的人类肠道 DNA 病毒组谱。关键特征是鉴定了包含 类尾巴噬菌体的核心病毒组,以及更多种类的 DNA 病毒,包括细胞外噬菌体和整合的前噬菌体。我们使用计算机模拟方法预测了 ME/CFS 微生物组中属成员和独特病毒之间的相互作用。因此,本研究为进一步研究肠道病毒组与细菌组之间与疾病相关的相互作用提供了更大患者队列研究的框架和依据。
