Species similar to or like Mimivirus
Genus of viruses, in the family Mimiviridae. Wikipedia
Filamentous bacteriophage in the genus Plectrovirus of the family Inoviridae, part of the group of single-stranded DNA viruses. The virus has many synonyms, such as SpV1-R8A2 B, Spiroplasma phage 1, and Spiroplasma virus 1, SpV1 (not to be confused with simply "SpV1" to refer to the entire spiroplasma virus morphological group 1).

- The giant mimivirus, in some sense an intermediate between tiny prokaryotes and ordinary viruses, was described in 2003 and sequenced in 2004.
- Mimivirus is one of the largest characterised viruses, with a capsid diameter of 400 nm.
- One comes from the discovery of unusually large and complex viruses, such as Mimivirus, that possess typical cellular genes.
- Of particular interest here is mimivirus, a giant virus that infects amoebae and encodes much of the molecular machinery traditionally associated with bacteria.
- Mimivirus, a nucleocytoplasmic large DNA virus with a genome size of about 1.1 megabases, was described in 1992 but not recognized as a virus until 2003.
- Mamavirus can be compared to the similar complex virus mimivirus; mamavirus was so named because it is similar to but larger than mimivirus.
- In similar manner, the sputnik virophage is dependent on mimivirus, which infects the protozoan Acanthamoeba castellanii.
- Megavirus is a viral genus containing a single identified species named Megavirus chilensis, phylogenetically related to Acanthamoeba polyphaga Mimivirus (APMV).
- Like the other very large viruses Mimivirus and Megavirus, Pandoravirus infects amoebas, but its genome, containing 1.9 to 2.5 megabases of DNA, is twice as large as that of Megavirus, and it differs greatly from the other large viruses in appearance and in genome structure.
- Acanthamoeba polyphaga mimivirus is its closest known relative, although the two viruses share less than one-third of homologous genes.
- The hypothesis was proposed by Philip Bell in 2001 and gained support as large, complex DNA viruses (such as Mimivirus) capable of protein biosynthesis were discovered.
- CroV is distantly related to Mimivirus and belongs to a group of viruses known as Nucleocytoplasmic large DNA viruses.
- A CeV strain was later found in the Gulf of Main in 2013 and the phylogenetic analysis of some specific marker confirmedits proximity with mimiviruses.
- As Klosneuviruses are related to Mimivirus, it was proposed to put them all together into a subfamily Megavirinae.
- In 2003, Didier Raoult identified with Bernard La Scola a giant amoebic virus, mimivirus, and in 2004 established its genome.
- The virus called Mimivirus infects amoebae.
- ASFV has similarities to the other large DNA viruses, e.g., poxvirus, iridovirus, and mimivirus.
- For example, viroplasms of mimivirus have a similar size to the nucleus of its host, the amoeba Acanthamoeba polyphaga.
- The replication strategy of faustovirus in amoeba is similar to that of mimivirus.
- It is a member of the Megavirales order with characteristics of phycodnaviridae and mimivirus families.
- While few giant viruses have been characterized in detail, the most notable examples are the phylogenetically related megavirus and mimivirus — belonging to the Megaviridae and Mimiviridae families, respectively — due to their having the largest capsid diameters of all known viruses.
- Brooks describes the huge and highly resistant Mimivirus found in Bradford, England in 1992 and whether this challenges the traditional view of viruses being inanimate chemicals rather than living things.
- Zamilon is restricted in its range of helper viruses; it can be supported by viruses from Mimivirus-like Mimiviridae lineages B and C, but not from lineage A. This appears to be a consequence of a rudimentary immune system of the helper virus, termed MIMIVIRE (mimivirus virophage resistance element), akin to the CRISPR-Cas pathway.
- The virophage has subsequently been shown to be capable of replicating in association with Moumouvirus and Monve, two Mimiviridae from lineage B, as well as with Terra1 and Courdo11 from lineage C; however, it cannot replicate in association with either Mimivirus or Mamavirus, classified as lineage A. This is unlike Sputnik, which can replicate in association with any Mimivirus-like member of Mimiviridae.
