Iotatorquevirus


Iotatorquevirus is a genus of viruses in the family Anelloviridae, in group II in the Baltimore classification. The genus has two species: Iotatorquevirus suida1a and Iotatorquevirus ursid17.

Virology

The virions are small and non-enveloped.
The viruses are usually acquired soon after birth and may invade virtually any tissue in the body.
They are widespread in the pig population.

Genome

Iotatorqueviruses have a circular, single-stranded DNA genome. The genome is negative-sense.

Clinical

Postweaning multisystemic wasting syndrome has been causally associated with porcine circovirus type 2. The Iotatorquevirus have also been linked with this syndrome but a causative role—if one exists—has yet to be established.
