Virion Properties

Morphology

Virions consist of an envelope, a matrix protein, a nucleoprotein complex, a nucleocapsid, and a polymerase complex. Virus capsid is enveloped. Virions are spherical to pleomorphic; filamentous forms occur. Virions measure 80-120 nm in diameter; 200-300 nm in length. The envelope surrounds one nucleocapsid. Surface projections are densely dispersed, distinctive spikes that cover the surface evenly and comprise esterase-esterase. Surface projections are composed of one type of protein. Surface projections are 10-14 nm long; 4-6 nm in diameter. Capsid/nucleocapsid is elongated and exhibits helical symmetry. The nucleocapsid is helical; and segments have different size classes with a length of 50-130 nm. The nucleocapsids are segmented with loops at one end.

Physicochemical and Physical Properties

The molecular mass (Mr) of virions is 250 x 106. Virions have a buoyant density in sucrose of 1.19 g cm-3. The sedimentation coefficient is 700-800 S20w (for non-filamentous particles). Virions are sensitive. Virions are sensitive to treatment with heat, lipid solvents, non-ionic detergents, formaldehyde, oxidizing agents. The infectivity is reduced after exposure to irradiation.

Nucleic Acid

The genome is segmented and consists of seven segments of linear negative-sense, single-stranded RNA. The complete genome is 10000 nucleotides long. The segment 1. Segment 2. Segment 3. Segment 4 has been fully sequenced, complete sequence is 1586 nucleotides long. Segment 5 has been sequenced, but only an estimate is presented, complete sequence is 600-1500 nucleotides long. The 5'-terminal sequence has conserved regions and repeats complementary to the 3'-terminus (5'-AGUAGACAUCAA..., terminal repeats at the 5'-end are 12 nucleotides long. The 3'-terminus has conserved nucleotide sequences; of 13 nucleotides in length; sequence has conserved regions (3'-UCGUU(A/U)UUGUUCG..., in all RNA species, or some RNA segments. The multipartite genome is encapsidated, each segment in a separate nucleocapsid, and the nucleocapsids are surrounded by one envelope.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins and non-structural proteins.

Biological Properties

Natural Host

Virus infects during its life cycle arthropod and vertebrate hosts. Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Animalia.

Kingdom Animalia
Phylum Arthropoda, or Chordata.

Phylum Vertebrata
Subphylum Vertebrata; Class Mammalia.

Class Mammalia Order Primates;
Family Hominidae.
Virus infects Homo sapiens (human).

Transmission and Vector Relationships

Virus is transmitted by a vector in a direct manner. Virus is transmitted by contact between hosts.

Vector Transmission:
Virus is transmitted by arthropods; arthropod-borne virus is transmitted by arachnids; arthropod-borne virus is transmitted by ticks. Virus is transmitted in a non-persistent manner; retained when the vector moults; replicates in the vector.
