Naesvirus
''Naesvirus'' is a genus of viruses in the family ''Myoviridae'', not assigned to a subfamily. Bacteria serve as the natural host, with transmission achieved through passive diffusion. There are five species in this genus. Taxonomy Species: :*''Burkholderia virus Bcep1'' :*''Burkholderia virus Bcep43'' :*''Burkholderia virus Bcep781'' :*''Burkholderia virus BcepNY3'' :*''Xanthomonas virus OP2'' Structure Naesviruses are viral envelope, nonenveloped, with a head and tail. Genome All five species have been fully sequenced and are available from ICTV. They range between 46k and 49k nucleotides, with 62 to 71 proteins. The complete genomes are available frohere 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 Ac ...

Myoviridae
''Myoviridae'' is a family of bacteriophages in the order ''Caudovirales''. Bacteria and archaea serve as natural hosts. There are 625 species in this family, assigned to eight subfamilies and 217 genera. Subdivisions The subfamily ''Tevenvirinae'' (synonym: ''Tequatrovirinae'') is named after its type species ''Enterobacteria phage T4''. Members of this subfamily are morphologically indistinguishable and have moderately elongated heads of about 110 nanometers (nm) in length, 114 nm long tails with a collar, base plates with short spikes and six long kinked tail fibers. The genera within this subfamily are divided on the basis of head morphology with the genus ''Tequatrovirus'' (Provisional name: ''T4virus'') having a head length of 137 nm and those in the genus ''Schizot4virus'' being 111 nm in length. Within the genera on the basis of protein homology the species have been divided into a number of groups. The subfamily ''Peduovirinae'' have virions with heads of 6 ...
