Anelloviridae

The Anelloviridae are a recently discovered family of viruses . They are classified as a vertebrate viruses and have a non-enveloped capsid, which is round with isometric, icosahedral symmetry.

The type species is torque teno virus (genus Alphatorquevirus).[1]

Genome

The genome is not segmented and contains a single molecule of circular, negative-sense, single-stranded DNA. The complete genome is 3000–4000 nucleotides long.[2]

Clinical

Anellovirus species are highly prevalent and genetically diverse. They cause chronic human viral infections that have not yet been associated with disease.[3]

Three genera are associated with human infections: Torque teno virus (TTV), Torque teno midi virus (TTMDV) and Torque teno mini virus (TTMV).
