The viruses circulating among Antarctic wildlife remain largely unknown. In an effort to identify viruses associated with Weddell seals (Leptonychotes weddellii) inhabiting the Ross Sea, vaginal and nasal swabs, and faecal samples were collected between November 2014 and February 2015. In addition, a Weddell seal kidney and South Polar skua (Stercorarius maccormicki) faeces were opportunistical...

Torque teno viruses (TTVs) are recently discovered DNA viruses, with heterogeneous genomes, highly prevalent in populations worldwide. The species that infect humans are Torque teno virus (TTV), Torque teno midi virus (TTMDV) and Torque teno mini virus (TTMV). High-resolution melting analysis (HRMA) is a sensitive and effective method for genotyping and mutation scanning. Up to now, HRMA has no...

Anellovirus (AV) is a ubiquitous virus in the human population. Individuals can be infected with multiple AV genera and species to form heterogeneous repertoire, termed anellome. Using advanced methods, we examined anellomes from 12 paired serum liver samples, as well 2701 subjects different clinical diagnoses. Overall, are remarkably individualized, significant among-group differences (Kruskal...

conclusions although significant differences (p < 0.01) were observed in the frequency of ttmdv/sav between healthy controls and each of the hiv positive and hiv/hcv co-infected individuals, no significant difference was observed between hiv positive and hiv/hcv co-infected cases, which may be due to hiv associated immunodeficiency. this is the first time that ttmdv/sav is reported in hiv infec...

BACKGROUND Torque Teno Midi Virus/Small Anellovirus (TTMDV/SAV) is a member of the Gammatorquevirus genus within the family Anelloviridae. It is detected in healthy, Hepatitis B Virus, Hepatitis C Virus and HIV infected individuals and also patients with acute respiratory disease in different countries, but its role in clinical diseases and its full geographical distribution is still unclear. ...

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...

24 Anellovirus is a group of single-stranded circular DNA viruses infecting human and other animal 25 species. Animal models combined with reverse genetics systems of anellovirus have not been 26 developed. We report here the construction and initial characterization of full-length DNA clones 27 of a porcine anellovirus, Torque teno sus virus 2 (TTSuV2), in vitro and in vivo. We first 28 demons...

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...
