TT virus (TTV) is widespread among the global population. Its pathogenic nature is still unclear but TTV seems to be more prevalent in cases of hepatitis than in healthy individuals. TTV harbours similarities to chicken anaemia virus (CAV). Here, the apoptotic potential of a putative TTV-derived 105 aa protein and of the main apoptosis-inducing agent of CAV, Apoptin, is compared. As the putativ...
To investigate the vertical transmission of the newly described TT virus (TTV), serum and breast milk samples from 46 women as well as sera from their 47 newborns were examined for the presence of TTV DNA by PCR. TTV DNA was detected in 47.8% (n = 22) of the women. All but one child born to these women were also viremic for TTV from the first sample onward. TTV DNA was found in 73.9% (n = 17) o...
Torque Teno Viruses (TTVs) are ubiquitous viruses which are highly prevalent in several mammalian species. Human TTV's are epidemiologically associated with several human disease conditions such as respiratory illnesses, auto-immune disorders and hepatitis. Recently it was found that swine TTV's (TTSuVs) can act as primary pathogens. The common occurrence of TTVs as environmental contaminants a...
By PCR screening, we found an extremely high prevalence of TT virus (TTV) in the general populations from different geographic regions. This suggests that TTV may be a common DNA virus with no clear disease association in humans. TTV genotyping by phylogenetic analysis was also performed.
BACKGROUND TT virus (TTV) is a recently discovered human DNA virus with worldwide distribution, but with no clear disease association. The possibility of an enhanced TTV virulence in patients with immunodeficiencies has not yet been investigated but is of particular interest because other viruses have been demonstrated to cause severe and rapid liver disease in such patients. Here we analysed t...
