Caudoviricetes ''Caudoviricetes'' is a class of viruses known as tailed viruses and head-tail viruses (''cauda'' is Latin for "tail"). It is the sole representative of its own phylum, ''Uroviricota'' (from ''ouros'' (ουρος), a Greek word for "tailed" + ...

''. Bacteria serve as the natural host, with transmission achieved through passive diffusion. There are two species in this genus.

Taxonomy

The following two species are assigned to the genus: * '' Lubbockvirus CD119'' * '' Lubbockvirus CDHM19''

Structure

Lubbockviruses are

nonenveloped A viral envelope is the outermost layer of many types of viruses. It protects the genetic material in their life cycle when traveling between host cells. Not all viruses have envelopes. A viral envelope protein or E protein is a protein in the env ...

, with a head and tail. The head has a diameter of about 50 nm. The tail is around 110 nm long, and is flexible and contractile.

Genome

Some species have been fully sequenced and are available from ICTV. They range between 50k and 57k nucleotides, with 75 to 82 proteins. The complete genomes are availabl

Life cycle

The virus attaches to the host cell using its terminal fibers, and ejects the viral DNA into the host cytoplasm via contraction of its tail sheath. Once the viral genes have been replicated, the procapsid is assembled and packed. The tail is then assembled and the mature virions are released via lysis.

History

According to the ICTV's 2010–11 report, the genus ''PhiCD119likevirus'' was first accepted as a new genus, at the same time as all three of its contained species. This proposal is currently unavailable, as th

The genus was later renamed to ''Lubbockvirus'' in 2019.
