Ranaviruses cause systemic infection in fish, amphibians and reptiles. Disease outbreaks associated with ranaviruses have been reported worldwide, and their harmful impact on aquaculture and natural populations of host animals has drawn attention to this group of viruses. In this research, genetic relationships among members of genus Ranavirus, including several known and less studied isolates, were investigated. Sequences of several viral genes were obtained and the phylogenetic analyses based on the sequence data were performed. The results confirm that the genus Ranavirus encompasses genetically divergent isolates. Most of the ranaviruses characterized to date are closely related to epizootic haematopoietic necrosis virus (EHNV) and frog virus 3 (FV3). Santee-Cooper ranaviruses and grouper iridoviruses cluster separately from the main group of ranaviruses. Methods based on polymerase chain reaction (PCR) and subsequent restriction enzyme analysis (REA) were developed for the detection and ...

PY - 2006/4/28. Y1 - 2006/4/28. N2 - A polymerase chain reaction (PCR) assay was developed for detection of white sturgeon iridovirus (WSIV). The synthetic oligonucleotides WS 229F and WS 245R generate a 519 bp DNA amplicon from the WSIV genome that encodes the putative major capsid protein (MCP) gene. The WSIV PCR detected as little as 1 fg of plasmid DNA as mixed with 100 ng of host DNA. No amplicons were detected with the WSIV PCR assay upon testing of genomic DNA from uninfected white sturgeon spleen cell line (WSS-2), uninfected white sturgeon tissues, white sturgeon adenovirus (WSAV), Acipenserid herpesvirus 2 (AcHV-2), frog virus 3 (FV-3), epizootic haematopoietic necrosis virus (EHNV), and red sea bream iridovirus (RSIV).

As a consequence of the high prevalence of TorqueTeno virus (TTV) in blood donors, thalassemia patients frequently acquire various genotypes of this virus through therapeutic blood transfusions. At present, the clinical consequences of TTV infection remain indeterminate for these patients. Here, several hundred thalassemia patients were tested for the presence of TTV and its genotypes using a combination of PCR and clone-based DNA sequencing. Approximately 10% (12/118) of the patients aged 2-20 years remained negative for TTV including eight genotypes of SENV. Ferritin, aspartate-aminotransferase (AST) and alanine-aminotransferase (ALT) levels were invariably lower in TTV-negative patients (P = 0.02, |0.01, and 0.06, respectively) than in TTV-positive patients. Patients with TTV-HCV co-infection showed elevated ferritin and ALT levels compared with patients with TTV infection alone (P | 0.02 and P | 0.01). AST and ALT levels were within the normal range for all TTV-negative patients, whereas abnormal

TY - JOUR. T1 - Identification of a novel 23 kDa protein encoded by putative open reading frame 2 of TT virus (TTV) genotype 1 different from the other genotypes. AU - Tanaka, Y.. AU - Orito, E.. AU - Ohno, T.. AU - Nakano, T.. AU - Hayashi, K.. AU - Kato, T.. AU - Mukaide, M.. AU - Iida, S.. AU - Mizokami, M.. PY - 2000/1/1. Y1 - 2000/1/1. N2 - We report the entire open reading frames (ORFs) sequences of four TT virus (TTV) isolates, one genotype 2 (G2) and three G4 isolates. Despite a DNA virus, TTV possesses high rate of amino acid (aa) substitution: the aa sequence homology of ORF1 and 2 is lower than the nucleotide homology. The partial N22 region of ORF1 is suitable for genotyping of prototype TTV isolates, because the phylogenetic tree from partial N22 sequence is consistent with that from the entire ORF1. Based on our sequence data, ORF2 from most isolates excluding G1 encode truncated 49 aa (pORF2a) because of an in-frame stop codon, although ORF2s from most G1 isolates encode 202 ...

TT virus (TTV) was the first member of the new family Anelloviridae to be discovered. TTV, for transfusion transmitted virus or torque teno virus was first reported in a Japanese patient in 1997 by the research scientist T. Nishizawa. The virus is extremely common, even in healthy individuals-as much as 100% prevalent in some countries, and in approximately 10% of blood donors in the UK and the US. Although it does not appear to cause symptoms of hepatitis on its own, it is often found in patients with liver disease. For the most part, TTV infection is believed to be asymptomatic. Initially found in Japanese patients with hepatitis of unknown cause, TTV was detected in various populations without proven pathology, including blood donors. This new virus was initially discovered in 1997 by means of representational difference analysis (RDA) in the plasma of a Japanese patient (initials T.T.) with posttransfusion hepatitis. A sequence (N22) of 500 nucleotides (nt) was first characterized and ...

Cancer affects millions of people worldwide each year. Although effective treatments have been established for many forms of the disease, these therapies target the tumor suppressor p53, which is not involved in all cancers. It is thus critical to seek novel treatment methods that can affect cancers independent of p53. One group of homologous viruses have been found to code for a set of homologous proteins that selectively induce apoptosis in transformed cells in a p53 independent manner. This group includes the human homolog Torque Teno Virus (TTV). In order to explore TTV VP3s potential as a cancer therapeutic, several experiments concerning localization and multimerization were performed to evaluate and compare the apoptotic pathways of the highly characterized CAV Apoptin and TTV VP3.

Les Myeloid-Derived Suppressor Cells (MDSC) sont une population hétérogène de cellules myéloïdes immatures, regroupées en deux sous-populations : les monocytiques-MDSC (M-MDSC) et les polymorphonucléaires-MDSC (PMN-MDSC). Ces cellules ont des capacités immunosuppressives et peuvent exprimer le ligand PD-L1 induisant lanergie des lymphocytes T qui expriment le marqueur PD-1. Au cours du sepsis, divers bouleversements immunologiques surviennent, et la fonction majeure des MDSC est probablement de réguler lhyper-inflammation en participant à létat dimmunodépression rencontré chez les patients. Ceux-ci ont alors un risque de développer des infections secondaires, et de réactiver des virus jusque-là en latence. Notre étude a pour objectifs de mettre en évidence lorigine des MDSC dans le sepsis, et dapprofondir leurs rôles dans létat dimmunosuppression, notamment dans la réactivation du Torque Teno Virus (TTV). Nos résultats montrent tant ex vivo quin vitro, que dans le sepsis,

Microbial DNA induces the expression of type I IFNs and proinflammatory cytokines, leading to the potent induction of innate immunity (Stetson and Medzhitov, 2006a; Kawai and Akira, 2009). Furthermore, synthesized DNA stimulates the innate immune system and acts as a good adjuvant to induce the efficient induction of acquired immune responses (Ishii et al., 2008a). Indeed, TLR9, the receptor for single-stranded DNAs containing unmethylated CpG motifs, is involved in the protection of hosts suffering DNA virus infection, and the ligands for TLR9 efficiently induce acquired immune responses upon vaccination. However, dsDNA derived from bacteria and DNA viruses, as well as host genomic DNA from dying cells, could induce the expression of both type I IFNs and IFN-inducible genes via a TLR-independent pathway (Okabe et al., 2005; Ishii et al., 2006; Stetson and Medzhitov, 2006b; Stetson et al., 2008). Although the specific sensors involved in dsDNA-induced innate immune responses are still unclear, ...

Background: In 1997, a novel DNA virus was isolated from the serum of a patient in Japan, and it was named TT virus (TTV).

Torque Teno virus (TTV) has been associated with non A-G hepatitis. The goal of this study was to estimate the infection rates and genotypic characteristics of TTV in the State of Qatar. A total of 644 blood samples representing different nationalities: (i) Qatari (118) and (ii) non- Qatari (526) nationals (mostly from Arab and South Eeast Asia countries) were tested for the presence of TTV DNA by nested PCR. The majority (573) of the blood samples belonged to healthy blood donors, whereas 54 and 53 of the blood samples belonged to patients infected with hepatitis B virus (HBV) and hepatitis C virus (HCV), respectively. The results obtained showed that the TTV infection rates in the healthy blood donors, and those infected with HBV or HCV patients were 81.4, 90.75 and 84.9%, respectively. Significant association between TTV viremia and age, or nationality was observed. Sequence analysis of PCR fragments amplified from the 50-untranslated region (50- UTR) of all (531) TTV positive samples showed ...

Ranavirus is a genus of viruses, in the family Iridoviridae. There are four other genera of viruses within the family Iridoviridae, but Ranavirus is the only one that includes viruses that are infectious to amphibians and reptiles. Additionally, it is one of the three genera within this family which infect teleost fishes, along with Lymphocystivirus and Megalocytivirus. The family Iridoviridae is one of the five families of nucleocytoplasmic large DNA viruses. The Ranaviruses, like the Megalocytiviruses, are an emerging group of closely related dsDNA viruses which cause systemic infections in a wide variety of wild and cultured fresh and saltwater fishes. As with Megalocytiviruses, Ranavirus outbreaks are therefore of considerable economic importance in aquaculture, as epizootics can result in moderate fish loss or mass mortality events of cultured fishes. Unlike Megalocytiviruses, however, Ranavirus infections in amphibians have been implicated as a contributing factor in the global decline of ...

Author summary The regulation of type I interferon signaling pathway is dynamic sequential processes and must be tightly regulated to keep balance between antiviral immune and hyper-inflammatory responses. The precise regulation mechanisms of the innate immune signaling pathway are still worth studying. Here, we found a novel role of the interferon-inducible p200 family protein IFI204 that specifically inhibits the IRF7-mediated type I interferon production by negative control of the transcriptional activity of IRF7 in the nucleus at the late stage of RNA virus infection. Previous studies showed that IFI204 is involved in DNA sensing during DNA virus infection to initiate antiviral immune responses. We demonstrate that IFI204 can inhibit IRF7-mediated activation of type I IFN responses induced by RNA virus infection, which is in contrast with its role in IRF3 activation in cGAS-STING DNA sensing pathway during DNA virus infection. Such negative regulation may help to avoid hyper-inflammatory responses

Infection with Rana grylio virus (RGV), an iridovirus isolated in China in 1995, resulted in a high mortality rate in frogs. The complete genome sequence of RGV was determined and analyzed. The genomic DNA was 105,791 bp long, with 106 open reading frames (ORFs). Dot plot analysis showed that the gene order of RGV shared colinearity with three completely sequenced ranaviruses. A phylogenetic tree was constructed based on concatenated sequences of iridovirus 26 core-gene-encoded proteins, and the result showed high bootstrap support for RGV being a member of the genus Ranavirus and that iridoviruses of other genera also clustered closely. A microRNA (miRNA) prediction revealed that RGV could encode 18 mature miRNAs, many of which were located near genes associated with virus replication. Thirty-three repeated sequences were found in the RGV genome. These results provide insight into the genetic nature of RGV and are useful for laboratory diagnosis for vertebrate iridoviruses ...

Amphibians are declining worldwide, and one cause of this is infectious disease emergence. Mass mortalities caused by a virus or a group of viruses belonging to the genus Ranavirus have occurred in wild common frogs Rana temporaria in England since the 1980s, and ranaviral disease is widespread in amphibians in North America and Canada, where it can also cause mass die-offs. Although there have be ...

The emergence of an infectious viral disease caused by the Chinese giant salamander iridovirus (GSIV) has led to substantial economic losses. However, no more molecular information is available for the understanding of the mechanisms associated with virus-host interaction. In this study, de novo sequencing was used to obtain abundant high-quality ESTs and investigate differentially-expressed genes in the spleen of Chinese giant salamanders that were either infected or mock infected with GSIV. Comparative expression analysis indicated that 293 genes were down-regulated and 220 genes were up-regulated. Further enrichment analysis showed that the most enriched pathway is complement and coagulation cascades, and significantly enriched diseases include inherited thrombophilia, immune system diseases, primary immunodeficiency, complement regulatory protein defects, and disorders of nucleotide excision repair. Additionally, 30 678 simple sequence repeats (SSRs) from all spleen samples, 26 ...
