Web7 mei 2024 · Yellow fever is an acute viral haemorrhagic disease transmitted by infected mosquitoes. The "yellow" in the name refers to the jaundice that affects some patients. Symptoms of yellow fever include … Flavivirus genomic RNA replication occurs on rough endoplasmic reticulum membranes in membranous compartments. New viral particles are subsequently assembled. This occurs during the budding process which is also responsible for the accumulation of the envelope and cell lysis. Meer weergeven Flavivirus is a genus of positive-strand RNA viruses in the family Flaviviridae. The genus includes the West Nile virus, dengue virus, tick-borne encephalitis virus, yellow fever virus, Zika virus and several other viruses which … Meer weergeven Flaviviruses have positive-sense, single-stranded RNA genomes which are non-segmented and around 10–11 kbp in length. In general, the genome encodes three structural proteins (Capsid, prM, and Envelope) and seven non-structural proteins (NS1, … Meer weergeven The positive sense RNA genome of Flavivirus contains 5' and 3' untranslated regions (UTRs). 5'UTR Meer weergeven The flaviviruses can be divided into two clades: one with vector-borne viruses and the other with no known vector. The vector clade, in turn, can be subdivided into a mosquito-borne clade and a tick-borne clade. These groups can be divided again. The … Meer weergeven Flaviviruses are enveloped and spherical and have icosahedral geometries with a pseudo T=3 symmetry. The virus particle diameter is around 50 nm. Meer weergeven Flaviviruses replicate in the cytoplasm of the host cells. The genome mimics the cellular mRNA molecule in all aspects except for the absence of the poly-adenylated (poly-A) tail. This feature allows the virus to exploit cellular apparatuses to synthesize … Meer weergeven Subgenomic flavivirus RNA (sfRNA) is an extension of the 3' UTR and has been demonstrated to play a role in flavivirus replication and pathogenesis. sfRNA is produced by incomplete degradation of genomic viral RNA by the host cells Meer weergeven
