虽然野生哺乳动物的许多病毒能够感染人类,但我们对人畜共患病可能性的了解尚不完整。病毒的通用性程度各不相同,其特征在于其宿主的系统发育关系。在这一系统发育景观的维度中,在寄生虫宿主范围的研究中很大程度上被忽视的系统发育聚集,在本研究中作为病毒人畜共患状态的关键预测因子出现。似是而非的,表现出聚集性的病毒,以相关宿主物种的离散集群为典型,可能(i)能够缩小与人类的系统发育距离,(ii)随后获得流行病学上相关的宿主,以及(iii)在已实现的宿主群落中表现出相对较高的适应性,这些宿主群落经常在系统发育上聚集。这些与系统发育聚集相关的机制可能有助于解释为什么相关的基本特征(如病毒在细胞质中复制的能力)与人畜共患病相关。
While many viruses of wild mammals are capable of infecting humans, our understanding of zoonotic potential is incomplete. Viruses vary in their degree of generalism, characterized by the phylogenetic relationships of their hosts. Among the dimensions of this phylogenetic landscape, phylogenetic aggregation, which is largely overlooked in studies of parasite host range, emerges in this study as a key predictor of zoonotic status of viruses. Plausibly, viruses that exhibit aggregation, typified by discrete clusters of related host species, may (i) have been able to close the phylogenetic distance to humans, (ii) have subsequently acquired an epidemiologically relevant host and (iii) exhibit relatively high fitness in realized host communities, which are frequently phylogenetically aggregated. These mechanisms associated with phylogenetic aggregation may help explain why correlated fundamental traits, such as the ability of viruses to replicate in the cytoplasm, are associated with zoonoses.
