Background: In 1997, a novel DNA virus was isolated from the serum of a patient in Japan, and it was named TT virus (TTV). As the virus is replicated in liver and has the ability to induce apoptosis in hepatocytes (Hepatocellular carcinoma cells) it is hypothesized that TTV is an opportunistic virus and in certain conditions causes liver damage. In this study the frequency of infection with TTV...
