BACKGROUND & OBJECTIVE The recent discovery of a novel parenterally transmitted, unenveloped, single-stranded DNA virus called TT virus (TTV) in chronic hepatitis patients with unclear pathogenesis throughout the world led us to investigate, its presence in chronic hepatitis patients attending a hospital in New Delhi, India, and to evaluate its role in liver disease. METHODS TT virus DNA was ...

The quantification of viral nucleic acids in serum by real-time PCR plays an important role in diagnosing hepatitis B virus and hepatitis C virus infection. In this study, we developed an assay using specific primers and probes to quantify hepatitis B virus DNA or hepatitis C virus RNA in serum from infected patients. For standardization and validation of the assay, an international panel of he...

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...
