Virus crystallisation is the re-arrangement of viral components into solid crystal particles. [1] The crystals are composed of thousands of inactive forms of a particular virus arranged in the shape of a prism. [2] The inactive nature of virus crystals provide advantages for immunologists to effectively analyze the structure and function behind ...
Metavirus is a genus of viruses in the family Metaviridae. [1] They are retrotransposons that invade a eukaryotic host genome and may only replicate once the virus has infected the host. [2]
Canine distemper virus is closely related to measles virus and is the most important viral disease of dogs. The disease (which was first described in 1760, by Edward Jenner, the pioneer of smallpox vaccination, is highly contagious, but is well controlled by vaccination. In the 1990s, thousands of African lions died from the infection, which ...
The family Filoviridae is a virological taxon that was defined in 1982 [3] and emended in 1991, [9] 1998, [10] 2000, [11] 2005, [12] 2010 [13] and 2011. [14] The family currently includes the six virus genera Cuevavirus, Dianlovirus, Ebolavirus, Marburgvirus, Striavirus, and Thamnovirus and is included in the order Mononegavirales. [13]
Flavivirus, renamed Orthoflavivirus in 2023, [3] is a genus of positive-strand RNA viruses in the family Flaviviridae.The genus includes the West Nile virus, dengue virus, tick-borne encephalitis virus, yellow fever virus, Zika virus and several other viruses which may cause encephalitis, [4] as well as insect-specific flaviviruses (ISFs) such as cell fusing agent virus (CFAV), Palm Creek ...
The detection of optical scattering and the gradient forces on micron sized particles was first reported in 1970 by Arthur Ashkin, a scientist working at Bell Labs. [1] ...
Like other members of the Paramyxoviridae family, it produces enveloped virions, and is a negative-sense single-stranded RNA virus. The virus is particularly fragile and is quickly inactivated by heat, desiccation, and sunlight. [14] Measles virus evolved from the then-widespread rinderpest virus most probably between the 11th and 12th ...
First described in 1954 by Bjorn Sigurdsson in Iceland, [6] Maedi-visna virus was the first lentivirus to be isolated and characterized, accomplished in 1957 by Sigurdsson. [6] [7] [8] Maedi (Icelandic mæði 'dyspnoea') and visna (Icelandic visna 'wasting' [9] or 'shrinking' of the spinal cord) refer to endemic sheep herd conditions that were only found to be related after Sigurdsson's work.
