ttv was first isolated from the serum of a japanese patient with post transfusion hepatitis of unknown etiology in 1977. ttv has been visualized by electron microscopy and was found to be an unenveloped, small, spherical particle with a diameter of 30-32 nm, and is a member of family related to circovridae family. the exact role of ttv in the pathogenesis of liver disease is yet to be establish...

BACKGROUND AND PURPOSE Transfusion-transmitted virus (TTV), a recently discovered DNA virus, was first identified in patients with non-A to -G hepatitis following blood transfusion. Transmission is generally via the parenteral route but recent data suggest that TTV can also be transmitted by the fecal-oral route. METHODS This cross-sectional study was conducted in March 2005 and included 324 ...

Torque Teno virus (TTV) is a transfusion transmitted virus that seems to be involved in several complications such as acute respiratory diseases, liver diseases, AIDS, cancer, and autoimmune reactions.  In the present study the frequency of TTV was investigated among β- thalassemia (BT) and haemodialysis (HD) patients (high risk patients for TTV) in Mazandaran province, Iran. DNA was ...

Background and Aims: Torque teno virus (TTV) is a DNA virus that isolated from the serum of a Japanese patient without A-G transfusion-transmitted hepatitis and other etiology. TTV is detectable in plasma and peripheral blood mononuclear cells, different body fluids and secretions such as stools, saliva, semen, vaginal fluid. The genome exhibits high diversity that has enabled the determination...

TT virus (TTV) is a newly discovered transfusion-transmissible DNA virus, which may cause posttransfusion hepatitis. The virus was detected in 12% of Japanese blood donors. The aim of the study is to investigate the prevalence and clinical influence of TTV in bone marrow transplant (BMT) recipients. Sera from 25 BMT recipients obtained 6 to 12 weeks after the transplant were examined for TTV-DN...

TTV is an unenveloped circular single-stranded DNA virus with a diameter of 30-32 nm that first was described in 1997 in Japan. TTV was detected in various populations without proven pathology, including blood donors and in patients with chronic HBV and HCV hepatitis. The aim of this study was to determine the prevalence of TTV DNA in Iranian patients with chronic hepatitis B and C. Viral TTV-D...
