New prevalence estimate of Torque Teno virus (TTV) infection in healthy population and patients with chronic viral hepatitis in Jiujiang, China

Torque Teno Virus (TTV) Infection

TTV has been recently identified as a causative agent of non-A to non-G hepatitis. However, the exact role of this virus in the pathogenesis of chronic liver disease (CLD) and the development of hepatocellular carcinoma (HCC) remain controversial. To clarify these issues, the prevalence of this virus and its impact on the severity of liver disease and development of HCC among Egyptian patients ...

Molecular Epidemiology of Torque Teno Virus (TTV) Isolated from in Healthy and Subjects with Chronic Hepatitis B and C in Jahrom City of Iran

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...

Prevalence and Genotyping of Torque Teno Virus in HBV/HIV and Chronic HBV Patients in Iran

Background: Torque teno virus (TTV) was the first human Anelloviridae detected in a Japanese patient with an unknown type of hepatitis in 1997. TTV is by far the first known single-stranded circular DNA virus infecting human. In spite of its widespread nature in human population, its pathogenesis is still unclear. In addition, information regarding TTV infection in Iranian population is limited...

Torque teno virus (TTV) infection in sows and suckling piglets.

Torque teno virus (TTV) is a single-stranded DNA virus that has been detected in serum of primate and non-primate species including swine. Little information on swine TTV infection and transmission dynamics is nowadays available. The goal of this study was to gain insight into the potential role of the sow in transmitting TTV to piglets and the infection dynamics of both swine TTV genogroups (T...
