Pandoravirus
''Pandoravirus'' is a genus of giant virus, first discovered in 2013. It is the second largest in physical size of any known viral genus. Pandoraviruses have double stranded DNA genomes, with the largest genome size (2.5 million base pairs) of any known viral genus. Discovery The discovery of Pandoraviruses by a team of French scientists, led by husband and wife Jean-Michel Claverie and Chantal Abergel, was announced in a report in the journal ''Science'' in July 2013. Other scientists had previously observed the pandoravirus particles, but owing to their enormous size they were not expected to be viruses. Patrick Scheid, a parasitologist from the Central Institute of the Bundeswehr Medical Service in Koblenz, Germany, found one in 2008, in an amoeba living in the contact lens of a woman with keratitis. Its development within the amoebal host was documented extensively. Unlike in other cases with such giant viruses, the large particles within ''Acanthamoeba'' were not mistak ...

Megavirales
''Nucleocytoviricota'' is a phylum of viruses. Members of the phylum are also known as the nucleocytoplasmic large DNA viruses (NCLDV), which serves as the basis of the name of the phylum with the suffix - for virus phylum. These viruses are referred to as nucleocytoplasmic because they are often able to replicate in both the host's cell nucleus and cytoplasm. The phylum is notable for containing the giant viruses. There are nine families of NCLDVs that all share certain genomic and structural characteristics; however, it is uncertain whether the similarities of the different families of this group have a common viral ancestor. One feature of this group is a large genome and the presence of many genes involved in DNA repair, DNA replication, transcription, and translation. Typically, viruses with smaller genomes do not contain genes for these processes. Most of the viruses in this family also replicate in both the host's nucleus and cytoplasm, thus the name nucleocytoplasmic. Th ...

Pandoraviridae
''Pandoraviridae'' is a family of double-stranded DNA viruses that infect amoebae. There is only one genus in this family: ''Pandoravirus''. Several species in this genus have been described, including ''Pandoravirus dulcis'', '' Pandoravirus salinus'' and ''Pandoravirus yedoma''. History The viruses were discovered in 2013. Description The viruses in this family are the second largest known virus (~1 micrometer) in capsid length, after ''Pithovirus'' (1.5 micrometer). ''Pandoravirus'' has the largest viral genome known, containing double-stranded DNA of 1.9 to 2.5 megabase A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both D ... pairs. Evolution These viruses appear to be related to the phycodnaviruses.

Megavirus
Megavirus is a viral genus containing a single identified species named ''Megavirus chilensis'', phylogenetically related to Acanthamoeba polyphaga Mimivirus (APMV). In colloquial speech, Megavirus chilensis is more commonly referred to as just “Megavirus”. Until the discovery of pandoraviruses in 2013, it had the largest capsid diameter of all known viruses, as well as the largest and most complex genome among all known viruses. Discovery Megavirus was isolated from a water sample collected in April 2010 off the coast of Chile, near the marine station in Las Cruces, by Jean-Michel Claverie and Chantal Abergel from the Structural & Genomic Information laboratory (IGS, CNRS and Aix-Marseille University). Megavirus was isolated by co-cultivation with a variety of ''Acanthamoeba'' laboratory strains ('' A. polyphaga'', '' A. castellanii'', '' A. griffini'') following a protocol pioneered by Timothy Rowbotham for isolating intracellular parasitic bacteria. Megavirus infects a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pandoravirus Yedoma
''Pandoravirus yedoma'', also known as ''P. yedoma'', is a virus that originated 48,500 years ago that was discovered in the deep Siberian permafrost in 2022. The scientists also revived 13 new pathogens and characterized them as 'zombie viruses'. It has been shown to infect amoeba An amoeba (; less commonly spelled ameba or amœba; plural ''am(o)ebas'' or ''am(o)ebae'' ), often called an amoeboid, is a type of cell or unicellular organism with the ability to alter its shape, primarily by extending and retracting pseudop ... cells, killing them in the process. https://www.newsweek.com/fact-check-zombie-virus-permafrost-siberia-pandoravirus-yedoma-1763191 References {{Virus-stub ...
