Bcep78likevirus 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 currently five species in this genus, including the type species Burkholderia phage Bcep781.

Taxonomy

Species:

  • Burkholderia phage Bcep1
  • Burkholderia phage Bcep43
  • Burkholderia phage Bcep781 (type species)
  • Burkholderia phage BcepNY3
  • Xanthomonas phage OP2
  • Structure

    Bcep78likeviruses are 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 from here.

    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 Bcep78likevirus was first accepted as a new genus, at the same time as all five of its contained species. This proposal is available here.
