The Big Picture Book of Viruses: Flaviviridae


Taxonomy: Synonym(s): Flavivirus group. Description is on the taxonomic level of family. Taxon contains the following Genera: Flavivirus, Pestivirus, "hepatitis C-like viruses".

Host: Taxon infects vertebrates.

Genome: Linear; single stranded; RNA. Genome monopartite. Genomic nucleic acid positive sense; infectious. Total genome 10000-11000 nucleotides long. 3' terminus has no poly (A) tract. 5' terminus has a methylated nucleotide cap, or a genome-linked protein (VPg).

Morphology: Virions uniform in shape; spheroidal; enveloped; 40-60 nm in diameter. Surface projections of envelope small (surface appears rough), or distinct (and are obvious fringes in negative stains). Nucleocapsids isometric; 25-30 nm in diameter. Symmetry polyhedral.
