Abstract:

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 Transfusion Organization were collected. A total of 25 human serum samples from hepatitis B and 25 samples from hepatitis C infected patients were also collected from Mahdieh diagnostic laboratory in Isfahan, Iran. Viral DNA was extracted and Torque Teno Mini Virus DNA was detected using a nested PCR with primer sets designed for a conserved region of the Torque Teno Mini Virus genome. PCR and Reverse transcriptase PCR were used for detection of HBV and HCV respectively. Results: Torque Teno Mini Virus -DNA was detected in 17% of healthy individuals. It also was detected in 20% and 48% of serum samples from hepatitis B and C infected individuals, respectively. The frequency of Torque Teno Mini Virus was significantly higher in hepatitis C patients versus healthy individuals (P < 0.05). Also, the frequency of TTMV in hepatitis C patients was significantly higher than hepatitis B patients (P < 0.05). Conclusions: The difference in Torque Teno Mini Virus frequency between the hepatitis C and healthy group was significant (P< 0.05). The etiology of the higher infection rate in hepatitis C individuals needs to be determined. Keywords: Torque Teno Mini Virus, Hepatitis B, Hepatitis C, PCR.

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...

Torque teno mini virus infection in chronic cervicitis and cervical tumors in Isfahan, Iran.

OBJECTIVES Torque teno mini virus (TTMV) is classified as the Betatorquevirus genus of Anelloviridae. Little is known about the prevalence of TTMV in humans. Worldwide, cervical cancer is the second most common cancer affecting women. This study aimed to estimate the TTMV infection frequency in cervicitis cases and cervical tumors including intraepithelial neoplasia (CIN), squamous cell carcino...

Hepatitis C virus infection and genotypes in blood donors

Abstract: Genotyping of the hepatitis C virus (HCV) is important for designing therapeutic strategies and regional specific diagnostic assays. The aim of this study was to identify the HCV genotypes in HCV infected blood donors. This is the first report on HCV genotypes in blood donors in Iran. In this cross-sectional study, 103 blood donors with hepatitis C were investigated for HCV genotype...

Background: The human T-cell lymphotropic virus type I is the first retrovirus idenfied in humans. The virus has been associated with adult T-cell leukemia/lymphoma, human T-lymphotropic virus type I, myelopathy/tropical spasc paraparesis, uveis, arthris, pulmonary lymphocyc alveolis, keratoconjuncvis sicca, and infecous dermas. Human T-lymphotropic virus type Iis endemic in Japan...
