Iotatorquevirus is a genus of viruses in the family Anelloviridae, in group II in the Baltimore classification. It includes one species: Iotatorquevirus suida1a.[1]

Virology

The virons 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]
