Torque 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...
متن کاملHigh 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 کاملInfection dynamics of Torque teno sus virus types 1 and 2 in serum and peripheral blood mononuclear cells.
This study was carried out to investigate the presence of Torque teno sus virus types 1 (TTSuV1) and 2 (TTSuV2) in a longitudinally (14 to 150 days of age) collected paired pooled sera (pSE) and peripheral blood mononuclear cells (pPBMCs) using nested polymerase chain reaction. The detection rate of TTSuV1 in pSE increased from 14 to 90 days of age, but a progressive decline was observed from 1...
