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. [1]

Contents

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. [2]

They are widespread in the pig population. [3] [4]

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. [5] The Iotatorquevirus have also been linked with this syndrome but a causative role—if one exists—has yet to be established. [6]
