Mimivirus, short for "mimicking microbe", is so called to reflect its large size and apparent Gram-staining properties. Mimivirus has a large and complex genome compared with most other viruses. Until 2013, when a larger virus Pandoravirus was described, it had the largest capsid diameter of all known viruses.
Megavirus also joins a group of large viruses known as nucleocytoplasmic large DNA viruses (NCLDV), although this term appears increasingly inappropriate to designate viruses replicating entirely within the cytoplasm of their hosts through the de novo synthesis of large virion factories. Megavirus and Mimivirus share 594 orthologous genes ...
Big Farm Virus belongs to the dangerous malware group of the Trojans. What we call a Trojan is a kind of a virus that can have numerous diverse usages. This makes these malware-based programs so awfully dangerous and frightening.
The interplay between the virus size and the genome length can be captured via the packing ratio which is the percent fraction of the capsid volume taken by viral DNA. For phage lambda it can be calculated to be about 40% whereas for HIV it is more than 10 times lower (BNID 111591).
But their new virus ... Proceedings of the National Academy of Sciences, is an astonishing 1.5 micrometers long, between 10 and 100 times as large as the average-sized virus.
Virus - Virus - Size and shape: The amount and arrangement of the proteins and nucleic acid of viruses determine their size and shape. The nucleic acid and proteins of each class of viruses assemble themselves into a structure called a nucleoprotein, or nucleocapsid.
It is so large and complex that researchers had trouble recognizing it as a virus. "We considered it a bacteria for a year and a half," said Didier Raoult of the Universite de la Mediterranee in ...
Kaspersky has an online virus scanner, too, that supports both files and URLs. A file you upload to this online virus scanner can be as large as 50 MB. The website couldn't be easier to use. Just paste the link or select the attachment icon to upload a file.
Although the virus is carried by other fish species, to date, it has produced disease only in largemouth bass. Scientists do not know how the virus is transmitted or how it is activated into disease. In addition, they know of no cure or preventative, as is commonly the case with viruses.
Giant viruses, more than twice as big as the last largest known viruses, have now been unearthed from sludge across the world, researchers say. Even more titanic viruses might await discovery, the ...
