High Prevalence of Co-Infection with Multiple Torque Teno Sus Virus Species in Italian Pig Herds
Torque teno viruses (TTVs) are a large group of vertebrate-infecting small viruses with circular single-stranded DNA, classified in the Anelloviridae family. In swine, two genetically distinct species, Torque teno sus virus 1a (TTSuV1a) and 1b (TTSuV1b) are currently grouped into the genus Iotatorquevirus. More recently, a novel Torque teno sus virus species, named Torque teno sus virus k2b (TT...
متن کاملRescue of a porcine anellovirus (torque teno sus virus 2) from cloned genomic DNA in pigs.
Anelloviruses are a group of single-stranded circular DNA viruses infecting humans and other animal species. Animal models combined with reverse genetic systems of anellovirus have not been developed. We report here the construction and initial characterization of full-length DNA clones of a porcine anellovirus, torque teno sus virus 2 (TTSuV2), in vitro and in vivo. We first demonstrated that ...
متن کاملDetection of swine torque teno virus in Italian pig herds.
Anellovirus is a recently created, floating genus of viruses. Torque teno virus (TTV), the type species in the genus, was first discovered in a human patient with a post-transfusion hepatitis of unknown aetiology. Recently, TTV genetically related to but distinct from those discovered in humans have also been found in animals, including pigs. The aims of this study were to estimate the prevalen...
متن کاملTorque Teno Sus Virus (TTSuV) in Cell Cultures and Trypsin
Torque teno sus virus (TTSuV), a member of the family Anelloviridae, is a single-stranded, circular DNA virus, widely distributed in swine populations. Presently, two TTSuV genogroups are recognized: Torque teno sus virus 1 (TTSuV1) and Torque teno sus virus 2 (TTSuV2). TTSuV genomes have been found in commercial vaccines for swine, enzyme preparations and other drugs containing components of p...
متن کاملTorque teno sus virus 1 and 2 viral loads in faeces of porcine circovirus 2-positive pigs
Recently, studies have suggested an association between the Torque teno sus virus (TTSuV) and the Porcine circovirus-2 (PCV2) in PCV2-associated disease cases. The aim of this study was to verify TTSuVs loads in pig faeces from PCV2-positive animals with and without diarrhea from PCVADaffected and PCV2-unvaccinated herds. A total of 80 faecal samples were collected individually from nursery and...
