DNAウイルス
CroV is the sole member of the genus Cafeteriavirus in the family Mimiviridae within the proposed order Megavirales. Phylogenetic analysis indicates that the virus is a nucleocytoplasmic large DNA virus (NCLD virus). Acanthamoeba polyphaga mimivirus is its closest known relative, although the two viruses share less than one-third of homologous genes.
