Mouse Coronavirus
Murine coronavirus (M-CoV) is a virus in the genus ''Betacoronavirus'' that infects mice. Belonging to the subgenus ''Embecovirus'', murine coronavirus strains are :wikt:enterotropic, enterotropic or polytropic. Enterotropic strains include mouse hepatitis virus (MHV) strains D, Y, RI, and DVIM, whereas polytropic strains, such as JHM and A59, primarily cause hepatitis, enteritis, and encephalitis. Murine coronavirus is an important pathogen in the laboratory mouse and the laboratory rat. It is the most studied coronavirus in animals other than humans, and has been used as an animal disease model for many virological and clinical studies. Types Murine hepatitis virus Murine coronavirus was first discovered in 1949. The researchers isolated the virus from the brain, spinal cord, liver, lung, spleen, and kidney of a rat with symptoms of encephalitis and severe myelin injury, and gave it the strain name mouse hepatitis virus (MHV)-JHM. MHV is now the most studied coronavirus in anim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virion
A virion (plural, ''viria'' or ''virions'') is an inert virus particle capable of invading a Cell (biology), cell. Upon entering the cell, the virion disassembles and the genetic material from the virus takes control of the cell infrastructure, thus enabling the virus to Replication (virus), replicate. The genetic material (''Viral core, core'', either DNA or RNA, along with occasionally present virus core protein) inside the virion is usually enclosed in a protection shell, known as the capsid. While the terms "virus" and "virion" are occasionally confused, recently "virion" is used solely to describe the virus structure outside of cells, while the terms "virus/viral" are broader and also include biological properties such as the infectivity of a virion. Components A virion consists of one or more nucleic acid genome molecules (single-stranded or double-stranded RNA or DNA) and coatings (a capsid and possibly a viral envelope). The virion may contain other proteins (for examp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
