Comments "The order Megavirales, also known as nucleocytoplasmic large DNA viruses, contains 7 viral families: Poxviridae, Iridoviridae, Ascoviridae, Mimiviridae, Phycodnaviridae, Asfarviridae, and Marseilleviridae [13, 14]. Marseillevirus, the first representative of the Marseilleviridae family, was isolated because of its ability to prey on amoebae [primary source]. Marseillevirus possesses a 368-kb double-stranded DNA genome, the sixth largest known viral genome, enclosed in a 250-nm icosahedral capsid. In this study, [researchers] describe a new giant virus, termed “giant blood Marseillevirus” (GBM), recovered from blood donated by asymptomatic humans."
