Family Fuselloviridae



Species :

- Sulfolobus spindle-shaped virus 5, SSV5; circular double-stranded DNA 15,33 bp, sequence acc. no. EU030939

- Sulfolobus spindle-shaped virus 6, SSV6; circular double-stranded DNA 15,684 bp, sequence acc. no. FJ870915.1

- Sulfolobus spindle-shaped virus 7, SSV7; circular double-stranded DNA 17,602 bp, sequence acc. no. FJ870916

- Acidianus spindle-shaped virus 1, ASV1; circular double-stranded DNA 24,186 bp, sequence acc. no. FJ870917




The virions are spindle-shaped for SSV5 and SSV7, and pleomorphic for SSV6 and ASV1, exhibiting a wide range of morphotypes varying  from the standard spindle-shape to an elongated sausage shape. Spindle-shaped virions have multiple thin filaments attached to one of the pointed ends (white arrows); the pleomorphic virions have thick short filaments, forming a crown around the virion tip (black arrows). Scale bars, 200 nm.
