Torque Teno Sus Virus |
Iotatorquevirus is a recently discovered genus in the new family of Anelloviridae, in group II in the Baltimore classification. It encompasses the two type species of the Torque Teno Sus Virus 1 and 2.
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.[1]
They are widespread in the pig population[2][3]
Genome
The genome is a circular single stranded DNA molecule of negative polarity.
Clinical
Postweaning multisystemic wasting syndrome has been causally associated with porcine circovirus type 2.[4] The Iotatorquevirus have also been linked with this syndrome but a causative role—if one exists—has yet to be established.[5]
