Bacteria serve as natural hosts, with transmission achieved through passive diffusion.

The icosahedral head is about 60 nm in diameter, with covalently linked capsid proteins.

[3] The virus attaches to the host cell's adhesion receptors using its terminal fiber, and ejects the viral DNA into the host cytoplasm via long flexible tail ejection system.

[1] According to ICTV's 1996 report, the genus L5likevirus was first accepted under the name L5-like phages, assigned only to family Siphoviridae.

The whole family was moved to the newly created order Caudovirales in 1998, and the genus was renamed to L5-like viruses in ICTV's seventh report in 1999.
