最近发现了许多感染各种脊椎动物宿主的不同多瘤病毒，并且通常可以确定其完整的基因组序列。为了适应这种快速增长的多样性，国际病毒分类委员会（ICTV）多瘤病毒科研究组设计了一个基于宿主和序列的原理，用于更新多瘤病毒科的分类。应用这一点导致了许多分类学修订的建议，这些建议于2015年12月被ICTV执行委员会接受。基于观察到的大T抗原编码序列之间的距离，建立了定义和创建多瘤病毒种的新标准。四个属（α-，β，γ-和δ多瘤病毒），共包括73个物种。物种命名尽可能系统化-大多数物种名称现在由宿主物种的二项名称，其次是多瘤病毒和反映发现顺序的数字组成。希望这一重要的更新科分类将作为一个稳定的基础，为未来的分类发展。
Many distinct polyomaviruses infecting a variety of vertebrate hosts have recently been discovered, and their complete genome sequence could often be determined. To accommodate this fast-growing diversity, the International Committee on Taxonomy of Viruses (ICTV) Polyomaviridae Study Group designed a host- and sequence-based rationale for an updated taxonomy of the family Polyomaviridae. Applying this resulted in numerous recommendations of taxonomical revisions, which were accepted by the Executive Committee of the ICTV in December 2015. New criteria for definition and creation of polyomavirus species were established that were based on the observed distance between large T antigen coding sequences. Four genera (Alpha-, Beta, Gamma- and Deltapolyomavirus) were delineated that together include 73 species. Species naming was made as systematic as possible - most species names now consist of the binomial name of the host species followed by polyomavirus and a number reflecting the order of discovery. It is hoped that this important update of the family taxonomy will serve as a stable basis for future taxonomical developments.
