Indivirus (IndV) is a genus of giant double-stranded DNA-containing viruses (NCLDV).

This genus was detected during the analysis of metagenome samples of bottom sediments of reservoirs at the wastewater treatment plant in Klosterneuburg, Austria.

New Klosneuvirus (KNV), Hokovirus and Catovirus genera (all found in these sewage waters) were also described together with Indivirus, building up a putative virus subfamily Klosneuvirinae (Klosneuviruses) with KNV as type genus.

[1] Indivirus has a genome of 0.86 million base pairs (660 gene families).

GC content is 26.6 %[1] Classification of metagenome, made by analyzing 18S rRNA indicate that their hosts are relate to the simple Cercozoa.
