The subfamily Entomopoxvirinae is a related but distinct member of the family Poxviridae. These viruses share many biological features of the poxviruses of chordates, but instead infect the larvae of a number of insect families. The three genera that comprise the entomopoxviruses are the genus Alphaentomopoxvirus, infecting beetles; genus Betaentomopoxvirus, infecting butterflies, moths, grasshoppers, and locusts, and the genus Gammaentomopoxvirus infecting flies and mosquitoes. The entomopoxviruses, like their vertebrate counterparts, have a double-stranded linear DNA genome that is transcribed in a temporal fashion. Entomopoxviruses are occluded in a paracrystalline protein matrix, forming spheroids that protect the virus from environmental conditions. A number of genes are conserved between the entomopoxviruses and chordopoxviruses defining a minimal complement of poxvirus genes. The entomopoxviruses have some unique molecular features. This review covers pathogenesis, transcription, and molecular analysis of the entomopoxviruses. [ABSTRACT FROM AUTHOR]

The article deals with Entomopoxvirus B from the Poxviridae family. The virus has surface globular mulberry-shaped units of 40 nanometers in diameter. The genome of Entomopoxvirus B is terminally linked and contains inverted terminal repeats. The egress mechanism of the replication of the virus buds through the cell membrane, while the spheroids are released after cellular disintegration. The history of Entomopoxvirus B is presented.

The article provides information on Suipoxvirus from the Poxviridae family. The brick-shaped virus has biconcave DNA-containing core, and has distinct intracellular and extracellular enveloped form of virus. The central core region of Suipoxvirus are flanked by variable ends. The replication of Suipoxvirus start with receptor-mediated endocytosis. The history of Suipoxvirus is presented.
