Virions consist of an envelope, a tegument, a
nucleocapsid, and a core. Virus capsid is enveloped. Virions are spherical to
pleomorphic. Virions measure 150-200 nm in diameter.
Surface projections are densely dispersed, small spikes that cover evenly the surface. Teguments
do not display a structure and proteins in variable amounts
are arranged sometimes in an asymmetric layer located between envelope and capsid.
Capsid/nucleocapsid is round and exhibits icosahedral symmetry
(T=16). The capsid is isometric
and has a diameter of 100-110 nm. Capsids appear hexagonal in outline.
The capsomer arrangement is clearly visible. The capsid consists of 162
capsomers with a hexagonal base and a hole running half-way down
the long axis. The core consists of a fibrillar spool on which the DNA is
wrapped. The end of the fibers are anchored to the underside of the capsid
shell.
Capsids can be penetrated by stain and some appear dark in the center
(although intact envelope impermeable to stain). Incomplete particles are
common. They are cores lacking capsid shells.
The
genome is not segmented and contains a single molecule of linear
double-stranded DNA. Minor species of non-genomic nucleic
acid are also found in virions. The encapsidated nucleic acid is mainly of
genomic origin, but virions may also contain nucleic acid of host origin
including M host RNA and host rRNA (genome H, virions may contain one
subgenomic nucleic acid species. The complete genome is 145000-165000
nucleotides long. Genome is sequenced, but only an estimate is available,
complete sequence is 112000 nucleotides long (L-DNA of M genome). The
subgenomic RNA-2 is 1400-56000 bp long (H-DNA. The length depends on the
number of repeat units). The genome has a guanine + cytosine content of 36 %
(L-DNA), or 72 % (H-DNA of the M genome; stretch of quasi unique sequences low
in GC content flanked at both ends with numerous repeat sequences of high GC
content). The genome has terminally redundant sequences. The terminally
redundant sequences have reiterated terminal sequences that are tandemly
repeated (H-DNA, are reiterated, but not repeated internally. The genome
sequence is repeated at both ends. Each virion contains multiple copies of the
genome; 2 copies per particle (genome M and H).

The viral
genome encodes structural proteins and non-structural proteins located
in the envelope, capsid, and tegument.
Structural Proteins: Internal lipid membrane consists of
several proteins.
Lipids are
present and located in the envelope. The composition of viral
lipids is not exactly known. The lipids are of host origin
and are derived from nuclear or host cell membranes.
Natural Host
Virus infects during its life cycle a single type of vertebrate host.
Domain
Viral hosts belong to the Domain Eucarya.
Domain Eucarya
Kingdom Animalia.
Kingdom Animalia
Phylum Chordata.
Phylum Vertebrata
