LESSON 1: VIRUS MORPHOLOGY and ANATOMY Don’t let the word “morphology” scare you. It has a simple meaning. It is the study of the shape of something. That’s right, scientists could have said “let’s look at the shape” but they had to make up a complicated word that uses a Greek word so it would sound more “science-y.” Morphology of Viruses Plant viruses are usually described as 1. Elongated (Rigid Rod or Flexious thread): a. Rigid rod – (Ex) Tobacco mosaic virus (15 X300 nm) Barley stripe mosaic virus (20x 10 nm).

The icosahedral parvovirus particles contain just protein and DNA genome. The three capsid proteins are VP1, VP2, and VP3. Ebola virus morphology studies have been concentrated on human liver tissue (8) (CDC and Prince Leopold Institute of Tropical Medicine, Antwerp), guinea pig tissues (9) (Microbiological Research Establishment, Porton Down) and cell culture preparations (8,9,10) (all laboratories). Hepatitis B Virus 1. Morphology & Genome Organization. The human Hepatitis B Virus (HBV) is the prototype member of the family Hepadnaviridae, a group of small enveloped DNA-viruses found in mammals (woodchucks (WHV), ground squirrels (GSHBV), woolly monkeys (WMHBV)) and birds (pekin ducks (DHBV), grey herons HHBV)).

”LifeClean är effektiv mot de virus som anges i EN 14476 inklusive Adenovirus, Poliovirus och Murine norovirus som är icke-höljeförsedda virus, dessa är Viral Morphology Viruses are acellular, meaning they are biological entities that do not have a cellular structure. Therefore, they lack most of the components of cells, such as organelles, ribosomes, and the plasma membrane.

Virions are spherical in shape with a diameter of about 27nm. The particles are simple in that they are composed of a protein shell surrounding the naked RNA genome. Note - In this video I have mistakenly mentioned that viruses are unicellular in nature sorry for that.

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.

Before its eradication in 1979, infection resulted in a 30–35 percent mortality rate. A complete virus is known as a virion which consists of a nucleic acid, an outer protein coated capsid and occasionally an envelope. Viruses are 100 times smaller than bacteria and are known to be a microscopic parasite whose size ranges from 5 to 300 nanometers. 2019-06-08 Morphology of Viruses.
