关于微生物组多样性的研究充斥着当前的文献,但生态学的教训清楚地表明,多样性只是分析生态系统及其稳定性、结构和功能时需要考虑的因素之一。多样性测量可能是解释宏基因组数据的有用工具,但问题仍然是它们的信息量有多大以及它们可以为微生物组的状态提供什么见解。一项利用数学模型研究微生物群落生态动态的研究表明,多样性和稳定性可能并不总是相伴而生。这一发现与肠道微生物组领域相关,特别是因为健康状态和病理状态之间的多样性比较经常产生矛盾的结果。如果我们想更好地了解这个复杂的生态群落及其在人类健康和疾病中的作用,就需要扩大微生物组数据分析的方法。
Studies on microbiome diversity are flooding the current literature, yet lessons from ecology clearly demonstrate that diversity is just one factor to consider when analyzing an ecosystem, along with its stability, structure and function. Measures of diversity may be a useful tool for interpreting metagenomic data but the question remains as to how informative they are and what insight they may provide into the state of the microbiome. A study utilizing mathematical modeling to investigate the ecological dynamics of microbial communities has shown that diversity and stability may not always be concomitant. This finding is pertinent to the gut microbiome field, especially since diversity comparisons between healthy and pathological states frequently yield contradictory results. There is a need to broaden our approach to the analysis of microbiome data if we are to better understand this complex ecological community and its role in human health and disease.
