Flavivirus

 
a genus of flaviviruses of worldwide distribution, containing about 75 species in 9 serogroups. It includes the viruses that cause yellow fever, dengue, Japanese B encephalitis, Kyasanur Forest disease, St. Louis encephalitis, tick-borne encephalitis, and West Nile encephalitis. Mosquitoes are the most common vector, with some species being tick-borne and some having no known vector.

flavivirus

A member of the flavivirus genus of the Flaviviridae family. Flaviviruses are arthropod-borne (arbor) viruses and can cause encephalitic or meningitic diseases including Japanese encephalitis, West Nile virus encephalitis, St. Louis encephalitis and Murray Valley encephalitis.

We evaluated the specificity of the assays in a subgroup of 109 serum samples with a strong potential for causing flavivirus cross-reactions (non-Zika subgroup).
It has also been reported that the amino acids surrounding Asnl54 differ in ZIKV E and in other flavivirus, which may provide insight into the pathobiology of Zika virus (31).
The research team used recently developed genome-wide CRISPR screening technology to identify which of the interferon-induced genes played a major role in suppressing flavivirus infection.
Lanciotti and coworkers (12) reported that ZIKV-infected patients had IgM antibodies against dengue viruses, especially if ZIKV was a secondary flavivirus infection.
Flavivirus genomes are mentioned by short names and GenBank IDs.
The arboviral serology report on 17 November indicated evidence of infection with a flavivirus, according to neutralizing antibody testing, with a plaque reduction neutralization test (PRNT) titer > 1 280 for ZIKV (positive control titer > 320).
Standards for defining individual members of the genus Flavivirus (and indeed, for other virus genera) are still evolving, because the genetic sequence database is expanding.
Flavivirus virions are composed of a single positive-strand RNA genome, packaged by the viral capsid protein (C) in a host-derived lipid bilayer and surrounded by 180 copies of two structural proteins, envelope (E) and membrane (M) [9, 10].
