The family Ampullaviridae includes viruses with linear dsDNA genomes that replicate in hyperthermophilic archaea from the genus Acidianus. The virions have a unique champagne bottle-shaped morphology and consist of a nucleoprotein filament condensed into a cone-shaped core, which is encased by an envelope, with the base of the 'bottle' decorated with a ring of 20 filaments. Genome replication is presumably carried out by the virus-encoded protein-primed family B DNA polymerase. The bottle-shaped morphology is unprecedented among viruses of bacteria and eukaryotes and represents a group of archaea-specific virion morphotypes. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of the Ampullaviridae, which is available at www.ictv.global/report/ampullaviridae.
球形病毒科包括具有线性 dsDNA 基因组的病毒，这些病毒在来自超嗜热古菌属 Acidianus 的嗜热古菌中复制。病毒粒子具有独特的香槟酒瓶形状的形态，由凝聚成锥形核心的核蛋白丝组成，核心被包膜包裹，“瓶子”的底部装饰有 20 根丝组成的环。基因组复制可能由病毒编码的蛋白引发的 B 族 DNA 聚合酶进行。在细菌和真核生物的病毒中，这种瓶状形态是前所未有的，代表了一组专性古菌的病毒形态类型。这是国际病毒分类委员会（ICTV）关于球形病毒科分类报告的摘要，可在 www.ictv.global/report/ampullaviridae 上查阅。
