Zoonoses are infectious agents that are transmissible between animals and humans. Up to 60% of known infectious diseases and 75% of emergent diseases are zoonotic. Genomic variation between homeostatic populations provides a novel window into the effect of environmental pathogens on allelic distributions within the populations. Genodynamics is a biophysical approach utilizing developed metrics on biallelic single-nucleotide polymorphisms (SNPs) that can be used to quantify the adaptive influences due to pathogens. A genomic free energy that is minimized when overall population health is optimized describes the influence of environmental agents upon genomic variation. A double-blind exploration of over 100 thousand SNPs searching for smooth functional dependencies upon four zoonotic pathogens carried by four possible hosts amidst populations that live in their ancestral environments has been conducted. Exemplars that infectious agents can have significant adaptive influence on human populations are presented. One discussed SNP is likely associated with both adaptive and innate immune regulation. The adaptive response of another SNP suggests an intriguing connection between zoonoses and human cancers. The adaptive forces of the presented pathogens upon the human genome have been quantified.
人畜共患病是可在动物和人类之间传播的传染性病原体。高达 60%的已知传染病和 75%的新发传染病都是人畜共患病。在稳态种群之间的基因组变异为环境病原体对种群内等位基因分布的影响提供了一个新的窗口。Genodynamics 是一种生物物理方法,利用双等位基因单核苷酸多态性 (SNP) 的已开发指标,可以用于量化因病原体而产生的适应性影响。当整体人口健康得到优化时,基因组自由能最小化,描述了环境因素对基因组变异的影响。对超过 10 万个 SNP 进行了双盲探索,在四个可能的宿主携带的四个人畜共患病原体中寻找对种群中生活在其祖先环境的平滑功能依赖性。提出了传染病原对人类种群可能具有重要适应性影响的范例。讨论的一个 SNP 可能与适应性和先天免疫调节都有关。另一个 SNP 的适应性反应表明,人畜共患病和人类癌症之间存在有趣的联系。已量化了所提出的病原体对人类基因组的适应性力量。
