High prevalence of TT virus (TTV) and TTV-like minivirus in cervical swabs.
نویسندگان
چکیده
Genomes of TT virus (TTV) and TTV-like minivirus DNA were detected in 80% and 61% of cervical swabs from healthy women, respectively, regardless of concurrent human papillomavirus infection. These results show that the potential exists for sexual transmission of TTV and related viruses.

Distribution of TT virus (TTV), TTV-like minivirus, and related viruses in humans and nonhuman primates.
TT virus (TTV) and TTV-like minivirus (TLMV) are small DNA viruses with single-stranded, closed circular, antisense genomes infecting man. Despite their extreme sequence heterogeneity (>50%), a highly conserved region in the untranslated region (UTR) allows both viruses to be amplified by polymerase chain reaction (PCR). TTV/TLMV infection was detected in 88 of 100 human plasma samples; amplifi...
متن کاملStudy on Prevalence of TTV among Cirrhotic patients due to Hepatitis B & C in Ahwaz University Hospitals during the Years 2004-2005
Background and Aims: Recently, a novel DNA virus was isolated from the serum of a patient with post-transfusion non A-G hepatitis and named TT virus. The aim of this study was to determine the prevalence TT virus among cirrhotic patients due to hepatitis B & C in infection Ahwaz. Methods: The prevalence of TTV infection was studied in 41 patients with liver cirrhosis. TTV DNA was detected ...
متن کاملGenomic and molecular evolutionary analysis of a newly identified infectious agent (SEN virus) and its relationship to the TT virus family.
A new group of transmissible single-stranded (ss) DNA viruses (SENV) distantly related to the large TT virus (TTV) family was recently identified. Eight different SENV isolates have been found, some with an association with posttransfusion hepatitis. A phylogenetic analysis of near-complete open-reading frame 1, including conserved motifs and excluding recombinant regions, was performed. The an...
متن کاملDetection of the Frequency of the Novel TT virus by PCR and Its Role in the Induction of Hepatic Injuries in Blood Donors in West Azerbaijan, Iran
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...

A sequence-independent PCR amplification method was used to identify viral nucleic acids in the plasma samples of 25 individuals presenting with symptoms of acute viral infection following high-risk behavior for human immunodeficiency virus type 1 transmission. GB virus C/hepatitis G virus was identified in three individuals and hepatitis B virus in one individual. Three previously undescribed ...
