abstract：:Previous reports documented the recovery of a DNA virus from a patient with posttransfusion non-A-G hepatitis and named TT virus (TTV). Although the virus was initially detected as a causative agent of hepatitis, there is doubt about its pathogenicity. The aim of this study was to clarify the relationship between TTV ...
