^aTwo of these seven sphaerolipovirus species have been isolated from extremophile bacterial hosts [21]
^bFor a recent discussion on the diversity of Mimiviridae and their taxonomic challenge, see Ref. [53]
^cClaverie and Abergel [53] list eleven members of the Mimiviridae family that have been physically isolated and fully sequenced, covering a genome length range of 370–1500 kbp and a particle size range of 140–600 nm (for the icosahedral shell)
