Similarity with Other Taxa

Tailed bacterial viruses resemble Tectiviridae by the presence of a tail-type structure for DNA injection, but differ from them by the permanent nature of their tailes. Tailed viruses resemble Herpesviridae in morphogenesis (use of scaffolding proteins, packageging of DNA into preformed shells, maturation of procapsids by proteolytic cleavage, and capsid expansion) and flow of replication. In addition, temperate tailed phages and Herpesviridae are able to establish latent infections.

Derivation of Name

Caudo: from Latin cauda, "tail"
Myo: from Greek mys, myos, "muscle", relating to the contractile tail
Podo: from Greek pous, "foot", for short tail
Sipho: from Greek siphon, "tube"
