在克罗恩病(CD)和溃疡性结肠炎(UC)患者中观察到肠道细菌种群多样性减少。对这些疾病中的病毒组知之甚少。我们发现,肠道病毒组是异常的CD和UC患者。对肠内游离病毒体富集制剂的深入分析显示,CD和UC与尾病毒目噬菌体的显著扩增相关。CD和UC患者的病毒组具有疾病特异性和群体特异性。重要的是,肠道病毒组的扩增和多样化似乎并不继发于细菌种群的变化。这些数据支持病毒组的变化可能导致肠道炎症和细菌生态失调的模型。我们的结论是,病毒组是一个候选人的贡献,或作为一个生物标志物,人类炎症性肠病,并推测肠道病毒组可能在其他疾病中发挥作用。
Decreases in the diversity of enteric bacterial populations are observed in patients with Crohn’s disease (CD) and ulcerative colitis (UC). Less is known about the virome in these diseases. We show that the enteric virome is abnormal in CD and UC patients. In-depth analysis of preparations enriched for free virions in the intestine revealed that CD and UC were associated with a significant expansion of Caudovirales bacteriophages. The viromes of CD and UC patients were disease- and cohort-specific. Importantly, it did not appear that expansion and diversification of the enteric virome was secondary to changes in bacterial populations. These data support a model in which changes in the virome may contribute to intestinal inflammation and bacterial dysbiosis. We conclude that the virome is a candidate for contributing to, or being a biomarker for, human inflammatory bowel disease and speculate that the enteric virome may play a role in other diseases.
