Group: Group V ((−)ssRNA)
Order: Unassigned
Family: Ophioviridae

Ophioviridae is a family of viruses characterized by an elongated and highly filamentous and flexible nucleocapsid with helical symmetry.[1][2]

The protein capsid is non-enveloped and has a constant diameter of 1500–2500 nm and a width of 3 nm, or 9 nm. The capsids form kinked circles, which can collapse to form linear duplex structures, much like a spring.[2]

The entire genome is 1100–1200 nucleotides long.[2][3]


The family has one genus, Ophiovirus, which has seven recognized species. Members of both the family and the genus are referred to as ophioviruses.[2]
