The family Plasmaviridae includes bacterial viruses with slightly pleomorphic, enveloped virions with a diameter of 50-125 nm. Virions contain infectious, circular, supercoiled dsDNA molecule(s) of approximately 12 kbp. Plasmaviruses infect Acholeplasma species, wall-less bacteria of the class Mollicutes, and are released by budding through the cell membrane without causing host cell lysis. Although the temperate bacteriophage Acholeplasma virus L2 of Acholeplasma laidlawii is currently the only classified plasmavirus, related prophages reside in the genomes of different Acholeplasma species, where they are integrated into tRNA genes. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of the Plasmaviridae, which is available at www.ictv.global/report/plasmaviridae.
质膜体病毒科包括具有稍显多形性、包膜的病毒粒子的细菌病毒，直径为 50-125nm。病毒粒子含有约 12kbp 的传染性、环形、超螺旋双链 DNA 分子。质膜体病毒感染无壁细菌柔膜体纲的节杆菌属物种，通过细胞膜出芽释放，而不会导致宿主细胞裂解。虽然温和噬菌体 Acholeplasma laidlawii 的 Acholeplasma 病毒 L2 是目前唯一分类的质膜体病毒，但相关原噬菌体存在于不同的节杆菌属物种的基因组中，在那里它们整合到 tRNA 基因中。这是病毒分类国际委员会（ICTV）关于质膜体病毒科分类报告的摘要，可在 www.ictv.global/report/plasmaviridae 上获得。
