"Tupanvirus", a new genus in the family Mimiviridae.

The genus "Tupanvirus" is a new proposed taxon to be included in the family Mimiviridae. The two known tupanvirus isolates were isolated from soda lake and oceanic sediments samples collected in Brazil and were named "tupanvirus soda lake" and "tupanvirus deep ocean", respectively. These viruses exhibit similarities to amoeba-infecting mimiviruses, but there are also several differences that place them in a separate group within the family Mimiviridae.

Acanthamoeba polyphaga mimivirus and other giant viruses: an open field to outstanding discoveries.

In 2003, Acanthamoeba polyphaga mimivirus (APMV) was first described and began to impact researchers around the world, due to its structural and genetic complexity. This virus founded the family Mimiviridae. In recent years, several new giant viruses have been isolated from different environments and specimens.
