“噬菌体”包括真细菌和古细菌的病毒。自1959年引入阴性染色以来，至少5568个噬菌体在电子显微镜下被检查过。大多数病毒粒子（96%）是尾部的。只有208个噬菌体（3.7%）是多面体、丝状或多形性的。噬菌体分属1目、17科和3个“浮动”类群。噬菌体存在于11个真细菌和古细菌门，可感染154个宿主属，主要是放线菌门、厚壁菌门和变形菌门。在有尾的噬菌体中，61%的噬菌体有长而不收缩的尾巴，属于虹膜病毒科。趋同进化在某些噬菌体群的形态上是可见的。
"Phages" include viruses of eubacteria and archaea. At least 5568 phages have been examined in the electron microscope since the introduction of negative staining in 1959. Most virions (96%) are tailed. Only 208 phages (3.7%) are polyhedral, filamentous, or pleomorphic. Phages belong to one order, 17 families, and three "floating" groups. Phages are found in 11 eubacterial and archaeal phyla and infect 154 host genera, mostly of the phyla Actinobacteria, Firmicutes, and Proteobacteria. Of the tailed phages, 61% have long, noncontractile tails and belong to the family Siphoviridae. Convergent evolution is visible in the morphology of certain phage groups.
