Phylogenetic Analysis of Torque Teno Virus in Hepatitis C Virus Infected Patients in Shiraz

BACKGROUND Torque teno virus (TTV) was the first human Circoviridae detected in a Japanese patient with unknown hepatitis in 1997. Subsequently, several studies performed to evaluate different aspects of Torque teno virus pathogenesis. OBJECTIVES The present study aimed to determine dominant genotype of Torque teno virus in chronic hepatitis disease using 5΄-UTR sequence among patients infect...

Clinical outcomes of Torque teno virus-infected thalassemic patients with and without hepatitis C virus infection

BACKGROUND Although a marked proportion of thalassemic patients acquire Torque teno virus (TTV) through blood transfusion, its clinical importance is unclear. This study was designed to investigate the clinical importance of TTV infection in thalassemic patients with and without hepatitis C virus (HCV) co-infection in Iran. METHODS In this case-control study, 107 thalassemic patients on chron...

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 ...

Torque teno virus: a ubiquitous virus

Torque teno virus (TTV) is a non-enveloped human DNA virus isolated by Nishizawa et al. in 1997.1 TTV, recently classified as the Alphatorquevirus genus within the Anelloviridae family by the International Committee on Taxonomy of Viruses (ICTV), was the first human virus with a single-stranded circular DNA genome to be identified.2 Thus far, five main genetic groups (Groups 1–5) involving at l...
