Structure of Hepatitis A Virus HAV (Hepatitis A Virus) is a distinct member of the picornavirus family, assigned to genus hepatovirus. HAV is a 27 nm to 32 nm spherical particle with icosahedral symmetry containing a linear single-stranded RNA genome with a size of 7.5 kb and non-enveloped. Hepatitis A virions have a primary buoyant density of 1.32 to 1.34 g/cc …
Structure of Rotavirus The name rotavirus is derived from the Latin word rota, meaning “wheel,” which refers to the virion’s appearance in negative-stained electron micrographs. Rotavirus falls under Reoviridae family and subfamily Sedoreovirinae, which appear more smooth, lacking the large surface projections. The virion has icosahedral symmetry and is triple-layered capsid lacking an envelope and measures 70–75 nm in diameter. …
Structure of Rabies Virus The virus is enveloped, rod shaped particles measuring 75 × 180 nm. Mature virion appears either as bullet shaped particles with one rounded and one flattened end or as bacilliform particles. The particles are surrounded by a membranous lipid envelope. The particles have a buoyant density in CsCl of about 1.19 g/cm3. The virion outer surface is …
Structure of Hepatitis C virus Hepatitis C virus (HCV) is a RNA virus belonging to the family Flaviviridae, genus Hepacivirus. The HCV virion is 55-65 nm in diameter containing in it a 9.6 kb positive sense single-stranded RNA genome composed of a long open reading frame (ORF) flanked by untranslated regions (UTR’s) at both the ends. The genome of HCV is …
