Torque teno sus virus (TTSuV) in tissues of pigs and its relation with the occurrence of postweaning multisystemic wasting syndrome.

Torque teno sus virus (TTSuV) is a member of the recently created family Anelloviridae. Two distinct species of TTSuVs, 1 (TTSuV1) and 2 (TTSuV2) have been reported so far in domestic pigs and wild boars. Although TTSuVs have not been clearly linked to any specific disease of pigs, a relation between TTSuV infections and postweaning multisystemic wasting syndrome (PMWS) has been suggested.
