Ultrastructure of Bodo saltans virus particles and its replication

Klosneuvirus (KNV, also KloV) is a new type of giant virus found by the analysis of low-complexity metagenomes from a wastewater treatment plant in Klosterneuburg, Austria. It has a 1.57-Mb genome coding unusually high number of genes typically found in cellular organisms, including aminoacyl transfer RNA synthetases with specificities for 19 different amino acids, over 10 and several tRNA-modifying enzymes.[1] Klosneuvirus, Indivirus, Catovirus and Hokovirus, are part of a group of giant viruses denoted as or , a proposed subfamily of the Mimiviridae.

Species in this clade include Bodo saltans virus infecting the kinetoplastid Bodo saltans.[2]

Phylogenetic tree topology of Mimiviridae is still under discussion. As Klosneuviruses are related to Mimivirus, it was proposed to put them all together into a subfamily Megavirinae.[2] Other authors (CNS 2018) like to put Klosneuviruses just together with Cafeteria roenbergensis virus (CroV) and Bodo saltans virus (BsV) into a tentative subfamily called Aquavirinae.[3]
