They found that these viruses mimic the infectious particles of several pathogenic flaviviruses in the finest details. There are four dengue virus serotypes (1-4), each of which is known to trigger mild to severe disease. Most areas of Australia do not have the type of mosquitoes that carry dengue, although outbreaks of the disease still occur in North Queensland every year when someone becomes infected overseas, then is bitten by a mosquito in Australia and that mosquito spreads the virus to others. The protein encoded by this gene is an interferon-induced membrane protein that helps confer immunity to influenza A H1N1 virus, West Nile virus, and dengue virus. Virion: Most virions are spheroidal or rod-shaped. The structure also reveals the presence of two zinc ion binding motifs. Dengue is a mosquito-transmitted virus that causes dengue fever, a flu-like illness. The genetic material is responsible for the infectivity while the proteins in the capsid are responsible for the specificity of the virus. The different shapes of a virus are helical, icosahedral, prolate, envelope, and complex. IgM capture and IgG capture ELISAs are the most common assays for this purpose. It does not show any metabolic activity. Dr. Rebeca Rico-Hesse’s laboratory is studying the structural (RNA and/or protein) and transmission (replication in Aedes aegypti) characteristics of dengue type 2 and type 3 virus variants that have produced dengue hemorrhagic fever in humans throughout the world.
