Mamavirus is a large and complex
virus in the
Group I family
mimiviridae. The virus is exceptionally large, and larger than many
bacteria. Mamavirus and other mimiviridae belong to
nucleocytoplasmic large DNA virus (NCLDVs) family. Mamavirus can be compared to the similar complex virus
mimivirus; mamavirus was so named because it is similar to but larger than mimivirus.
