Name, Synonyms and Lineage
Synonym(s):
Poxviruses of vertebrates. Virus is of the family
00.058.
Poxviridae.
Virions consist of an envelope, a surface membrane, a
core, and lateral bodies, or a surface membrane, a core, and lateral bodies.
During their life cycle, virions produce extracellular particles and produce
intracellular particles; can occur in two phenotypes; may be enveloped during
their extracellular phase. The infection is initiated by extracellular virions.
Virus may be sequestered within inclusion bodies that are not occluded
and typically contain one nucleocapsid. Virus capsid is enveloped. Virions are
ovoid, or brick-shaped, or pleomorphic. Virions measure
140-260 nm in diameter; 220-450 nm in length. Composed of an external
coat containing lipid and tubular or globular protein structures enclosing two
lateral bodies and a core, which contains the genome, displaying tubular
units, or regular spiral filaments. The core is biconcave with two lateral
bodies. Nested between the core membrane, or between the surface membrane.
Additional electron micrograph of
Poxviridae are found in the Picture Gallery.
Virions have a buoyant density in CsCl of 1.23-1.27 g
cm-3.
The
genome is not segmented and contains a single molecule of linear
double-stranded DNA. The complete genome is 130000-375000
nucleotides long. The genome has a guanine + cytosine content of 35-64 %.
The genome has terminally redundant sequences. The terminally redundant
sequences have reiterated inverted terminal sequences which are tandemly
repeated. The genome sequence is repeated at both ends. Double-stranded DNA is
covalently. Double-stranded DNA is cross-linked at both ends.
GenBank records for
nucleotide sequences;
complete genome sequences.
The viral
genome encodes structural proteins and non-structural proteins.
Lipids are
present and located in the envelope. Virions are composed of 4%
lipids by weight. The composition of viral lipids and host cell membranes are
similar. The lipids are host derived and synthesized de novo (during the
early phase of virus replication) and are derived from plasma
membranes. Viral membranes include glycolipids.
Natural Host
Virus infects during its life cycle a single type of vertebrate host.
Domain
Viral hosts belong to the Domain Eucarya.

Phylum Vertebrata
Subphylum Vertebrata.
Class Mammalia and Aves.
Class Mammalia Order Primates, Artiodactyla,

Virus infects Homo
sapiens (human).
