2354. Torque Teno Virus (TTV) and Epstein–Barr Virus (EBV) Viral Load in Peripheral Blood as a Biomarker of “Net Immunosuppression”: Factors Influencing Viral Load in Adult Patients Awaiting Solid Organ Transplantation Jutta Preiksaitis, MD, FRCP (C); Curtis Mabilangan, BSc; Yupin Tong, PhD; Catherine Burton, MD MSc and Simon Urschel, MD; Medicine, Infectious Diseases, University of Alberta, Ed...

Torque teno virus (TTV) is prevalent worldwide and has been extensively studied in human and some wild and domestic animals. As the studies on TTV in chickens was rare and there was no information about the infection of domestic village chickens with TTV and also structural resemblance of this virus to chicken anemia virus, the frequency of the infection in domestic village chickens in differen...

OBJECTIVE To investigate the rate of infection caused by Torque teno virus (TTV) in United Arab Emirates (UAEs) healthy population as a pilot study in detecting TTV DNA in 100 healthy blood donors. METHODS We randomly choose a total of 100 healthy blood donors who attended Zayed Military Hospital, Abu Dhabi, UAE from January 20 to May 30, 2005. We carried out a real-time polymerase chain reac...

In the process of searching for the recently described small anelloviruses 1 and 2 (SAVs) with the genomic DNA length of 2.2 or 2.6 kb in human sera, we isolated a novel virus with its genomic organization resembling those of torque teno virus (TTV) of 3.8-3.9 kb and torque teno mini virus (TTMV) of 2.8-2.9 kb. The entire genomic sequence of three isolates (MD1-032, MD1-073 and MD2-013), which ...

Background: Recently, some new viruses have been identified for their association with hepatitis which Torque Teno Mini Virus being among them. The aim of this study was to determine the frequency of Torque Teno Mini Virus in healthy individuals and hepatitis B and C patients in Isfahan, Iran. Materials and Methods: One hundred serum samples of healthy individuals from Isfahan Blood Transfusi...

Torque Teno virus (TTV) is a transfusion transmitted virus that seems to be involved in several complications such as acute respiratory diseases, liver diseases, AIDS, cancer, and autoimmune reactions.  In the present study the frequency of TTV was investigated among β- thalassemia (BT) and haemodialysis (HD) patients (high risk patients for TTV) in Mazandaran province, Iran. DNA was ...

Torque teno virus is a human non-enveloped singlestranded circular DNA virus with icosahedral symmetry and a particle size of approximately 30 nm. TTV was first characterised as a blood-borne virus and was initially referred to as transfusion-transmitted virus (Nishizawa et al. 1997). Its negative-sense genome is 3.6-3.9 kb in size (Mushahwar et al. 1999). Recently, it was renamed Torque teno v...

Ten years after the identification of the first partial sequences of Torque teno virus (TTV), more than 200 full-length related genomes have been characterized in humans and in several animal species. As suspected in the earlier stages of their description, a considerable genetic variability characterizes TTV and related viruses, the current members of the floating genus Anellovirous. Since inf...
