1 BASIC VIROLOGY VIRUS MORPHOLOGY: • Capsid: Composed of numerous repeating subunits. Viral genome is thus conserved in that a single protein can be transcribed many times to make the capsid. • Capsomere: Clusters of polypeptides which, when completely assembled, form the capsid.

Image 12476218. Apr 30, 2018 Viral morphology provides the basis for grouping viruses into families. A virus family may consist of members that replicate only in invertebrates,  Viruses are capable of latching onto host cells and getting inside them. H3N2 influenza virus particles © CDC / Science Photo Library. H3N2 influenza virus  Now, the viruses are surrounded by an outer protein coating called the capsid, which protects the viral genome and aids in its transfer between host cells.

14.18) is pleomorphic and its diameter is 80- 120 nm. It is an enveloped virus possessing genome segmented into eight linear single- stranded molecules ranging in size from 890 to 2341 nucleotides. Morphology: Viruses are grouped The virus possesses a negative-sense single-stranded RNA genome of approximately 13.3 kb encapsidated by multiple copies of the nucleoprotein (N), The varicella-zoster virus, like other herpesviridae, has an enveloped polyhedral structure. This type of structure has a polyhedral caspid surrounded by a membranous envelope. In the case of VZV, the caspid is icosahedral which means it is a regular shape with 20 triangular faces and 12 corners.

The virus can infect any mammal, and most die within weeks of infection. Smallpox is a human virus transmitted by inhalation of the variola virus, localized in the skin, mouth, and throat, which causes a characteristic rash. Before its eradication in 1979, infection resulted in a 30 to 35 percent mortality rate.

Picornaviruses are small, ether- insensitive viruses with an RNA genome. There are three poliovirus serotypes: serotype 1, 2, and 3.

Field, December 1988, Churchill Livingstone edition, Hardcover in English - 2nd edition Zika virus was discovered in Uganda in 1947. It’s a type of virus called a flavivirus. Other flaviviruses include dengue, yellow fever, and West Nile viruses. Like its relatives, Zika virus is mainly transmitted to humans through the bite of infected Aedes aegypti mosquitoes.

The Henipavirus family is pleomorphic, meaning their shape is varied, and traditionally 40 to 600 nm in diameter [9]. Morphology. Under the EM, virions appear roughly as spheres (some experts say they're "pleomorphic"), 40-65 nm in diameter.
