Molecular and biophysical characterization of TT virus: evidence for a new virus family infecting humans. (1/30)

The recent isolation of a novel DNA virus from the serum of a Japanese patient (T.T.) has provided the latest possible candidate virus associated with cryptogenic hepatitis. In the present study, we report the complete nucleotide sequence of this virus (TTV) isolated from the serum of a West African. Based on PCR studies designed to amplify overlapping regions of the viral genome and sensitivity to digestion with mung bean nuclease, the viral genome is circular and negative stranded, and comprises 3,852 nt, which is 113 nt longer than the prototype isolate from Japan. Cesium chloride density gradient centrifugation demonstrated banding of the virus at 1.31-1.34 g/ml; filtration studies indicated that TTV had a particle size of 30-50 nm. These results suggest that the virus is similar to the Circoviridae, viruses known to infect plants and vertebrates (e. g., birds and swine); however, sequence similarity searches of available databases did not reveal identity between TTV and other viruses. Phylogenetic analyses of a 260-nt region from 151 globally distributed isolates demonstrated the existence of three major TTV genotypes. Several individuals at high risk for infection with parenterally transmitted viruses were infected with more than one genotype. There was no correlation between genotype and geographic origin. Finally, intravenous inoculation of TTV-positive human serum into chimpanzees demonstrated that TTV can be transmitted to primates; no biochemical or histological evidence for hepatitis was obtained. The distinct biophysical and molecular characteristics of TTV suggest that it is a member of a new family of viruses, which we have tentatively named the Circinoviridae.  (+info)

Complete circular DNA genome of a TT virus variant (isolate name SANBAN) and 44 partial ORF2 sequences implicating a great degree of diversity beyond genotypes. (2/30)

Information on the entire genome of TT virus (TTV) has been scarce. The circular ssDNA genome of a variant (isolate name SANBAN) that we sequenced was only 56.7% homologous to the prototype isolate (TA278), with even lower homology at the amino acid level: 34.2% for ORF1 and 39.7% for ORF2. Regarding the ORF1, SANBAN was only very distantly related to the six major TTV genotypes reported to date. In partial ORF2 sequences determined on 44 isolates taken together, TTV has a broad range of genetic diversity and the SANBAN isolate may represent a new TTV-like viral species or genus and not merely a genotype of TTV.  (+info)

TT virus infection is widespread in the general populations from different geographic regions. (3/30)

By PCR screening, we found an extremely high prevalence of TT virus (TTV) in the general populations from different geographic regions. This suggests that TTV may be a common DNA virus with no clear disease association in humans. TTV genotyping by phylogenetic analysis was also performed.  (+info)

Detection of TT virus DNA in liver biopsies by in situ hybridization. (4/30)

A novel hepatitis-associated virus named TT virus (TTV) has been isolated. However, its hepatotropism has not been proven. We have retrospectively analyzed the presence of TTV-DNA by polymerase chain reaction (PCR) and in situ hybridization in liver biopsies from 30 patients with liver disease (15 TTV-DNA-positive and 15 TTV-DNA-negative in serum), and prospectively in serum and liver from eight patients with normal liver histology. TTV-DNA was detected by PCR in the liver from the 15 patients with serum TTV-DNA and in serum and liver of two of the eight patients without liver disease. TTV-DNA titers in liver were 10 times higher than in serum, although no correlation between TTV-DNA titers in serum and liver were observed. In situ hybridization shows positive signals in the hepatocytes of the 17 patients infected by TTV but in none of the TTV-DNA-negative patients by PCR. No morphological changes were observed in the hepatocytes showing hybridization signals. The percentage of positive hepatocytes ranged from 2.1% to 30% and correlated with the TTV-DNA titers in liver (r = 0.54; P = 0.037). In conclusion, our results show that TTV is able to infect liver cells although they do not support a role for TTV in causing liver disease.  (+info)

Mixed viral infection identified using heteroduplex mobility analysis (HMA). (5/30)

It is now recognised that mixed viral infection, or infection of an individual with two or more distinct strains of a single viral species, often occurs particularly with RNA viruses. Current methods for detection of mixed infection normally involve genotyping or cloning and DNA sequencing. These methods are not always accurate or sensitive at detecting mixed infection and cannot be used for large numbers of samples. Furthermore subsequent sequence determination of the coinfecting viruses is labour intensive. This paper describes a simple, generic method based upon PCR and heteroduplex mobility analysis (HMA) that can be used to rapidly determine mixed infection with two strains of the same virus. The utility of this method is illustrated with hepatitis C virus (HCV) and TT virus (TTV) as examples. PCR-HMA detected mixed infection in 3 (8%) of 38 sera from intravenous drug users (IVDU) and 28 (30%) of 70 TTV-positive sera from Australia, China, and Vietnam. HMA can also be used to screen recombinant colonies to identify the sequences of the coinfecting viruses. The methods described here could be applied to analyse any PCR product containing two or more divergent sequences, whether derived from viruses, bacteria, or eukaryotic organisms.  (+info)

Nucleotide sequence analysis of a novel circovirus of canaries and its relationship to other members of the genus Circovirus of the family Circoviridae. (6/30)

The circular, single-stranded DNA genome of a novel circovirus of canaries, tentatively named canary circovirus (CaCV), was cloned and sequenced. Sequence analysis indicated that the genome was 1952 nucleotides (nt) in size and had the potential to encode three viral proteins, including the putative capsid and replication-associated (Rep) proteins. The CaCV genome shared greatest sequence similarity (58.3% nt identity) with the newly characterized columbid circovirus (CoCV) and was more distantly related to the two porcine circovirus strains, PCV1 and PCV2, beak and feather disease virus (BFDV) and a recently isolated goose circovirus (GCV) isolate (46.8-50.9% nt identity). In common with other members of the Circovirus genus, several nt structures and amino acid motifs thought to be implicated in virus replication were identified on the putative viral strand. Phylogenetic analysis of both the capsid and Rep protein-coding regions provided further evidence that CaCV is more closely related to CoCV and BFDV and more distantly related to GCV, PCV1 and PCV2.  (+info)

Observation of positive selection within hypervariable regions of a newly identified DNA virus (SEN virus)(1). (7/30)

To elucidate the evolution of SEN virus (SEN-V), serial sequences of chronically SEN-V-infected patients were analyzed. In the hypervariable regions, non-synonymous substitutions significantly predominated. This could be attributed to positive selection in evading immune surveillance of the hosts and to establish a persistent infection. On the basis of the sequences in the two open reading frames of SEN-V DNA, the rate of synonymous substitutions was 7.32 x 10(-4) per site per year. Since this rate is close to RNA viruses and higher than other DNA viruses, the SEN-V might be replicated by machinery with poor or no proofreading function.  (+info)

Investigation of SEN virus infection in patients with cryptogenic acute liver failure, hepatitis-associated aplastic anemia, or acute and chronic non-A-E hepatitis. (8/30)

SEN virus (SENV) has been tentatively linked to transfusion-associated non-A-E hepatitis. We investigated SENV's role in unexplained hepatitis in other settings. Polymerase chain reaction amplification was used to detect 2 SENV variants (SENV-D and SENV-H) in 1706 patients and control subjects. SENV was detected in 54 (22%) of 248 patients with acute or chronic non-A-E hepatitis, 9 (35%) of 26 patients with hepatitis-associated aplastic anemia, and 0 of 17 patients with cryptogenic acute liver failure, compared with 150 (24%) of 621 control subjects with liver disease and 76 (10%) of 794 healthy control subjects. When controlling for geographic region, the prevalence of SENV among case and control subjects was not significantly different. The severity of acute or chronic hepatitis A, B, or C was not influenced by coexisting SENV infection. No etiological role for SENV in the cause of cryptogenic hepatitis could be demonstrated.  (+info)

Circoviridae is a family of viruses. Birds and mammals serve as natural hosts. There are currently 70 species in this family, divided among 2 genera. Diseases associated with this family include: PCV-2: postweaning multisystemic wasting syndrome; CAV: chicken infectious anemia. Viruses in the family Circoviridae are non-enveloped, with icosahedral and round geometries, and T=1 symmetry. The diameter is around 20 nm. Genomes are circular and non-segmented, around 3.8kb in length. The capsid consists of 12 pentagonal trumpet shaped pentamers. There are two main open reading frames arranged in opposite directions that encode the replication (Rep) and capsid (Cap) proteins. Alternative start codons are common in the avian species. Viral replication is nuclear. Entry into the host cell is achieved by penetration into the host cell. Replication follows the ssDNA rolling circle model. DNA templated transcription, with some alternative splicing mechanism is the method of transcription. The virus exits ...
This assessment is related to the publication of the identification of a new cyclovirus species, tentatively named cyclovirus-Vietnam (CyCV-VN), in cerebrospinal fluid of patients with acute central nervous system infection. However, there are insufficient data to assess the risk for disease occurrence in humans or potential of human-to-human transmission. Further studies should be encouraged in Europe and elsewhere to investigate the possible pathogenicity, epidemiology, and transmission patterns of cycloviruses. ...

The first step to producing our specially designed enzymes was to change the wild-type gene that codes for Kumamolisin to code instead for variant enzymes with our desired amino acid substitutions. We designed mutagenic oligonucleotide primers that would anneal to the wild-type Kumamolisin gene and incorporate point mutations that, when expressed, would result in a variant of Kumamolisin with the desired amino acid shift. To incorporate these mutations, we first isolated single stranded DNA (ssDNA) of our vector harboring the wild-type Kumamolisin gene. To do this we infected cells with bacteriophage M13, which packages its own ssDNA genome identified by length, and so in tandem packaged our vector in single stranded form. We then harvested the phage from the lysed culture of E. coli, and extracted our single stranded vector DNA. Next, we annealed and extended our mutagenic oligos to incorporate the specified mutations into the newly synthesized antisense strand. This hybrid vector was ...

Understanding emerging viruses is critical for disease monitoring and prediction; however, surveys of novel viruses are hindered by the lack of a universal assay for viruses. Viral metagenomics, consisting of viral particle purification and shotgun sequencing, is a powerful technique for discovering viruses in a wide variety of sample types. However, current protocols are not effective on tissue samples (e.g., lungs, livers and tumors), where they are hindered by the high amount of host nucleic acids which limits the percentage of sequences that originate from viruses. In this dissertation, a modified viral metagenomics protocol was developed and utilized to effectively purify viruses from tissues, enabling the sequencing of novel viruses from animals, plants, and insect vectors. Viral metagenomics performed directly on tissue samples enabled the discovery of novel vertebrate, plant, insect and bacterial viruses. From a sea turtle fibropapilloma, viral metagenomics revealed a novel tornovirus STTV1,
BACKGROUND: One of the most important global pathogens infecting all age groups is Streptococcus pneumoniae (the pneumococcus). Pneumococci reside in the paediatric nasopharynx, where they compete for space and resources, and one competition strategy is to produce a bacteriocin (antimicrobial peptide or protein) to attack other bacteria and an immunity protein to protect against self-destruction. We analysed a collection of 336 diverse pneumococcal genomes dating from 1916 onwards, identified bacteriocin cassettes, detailed their genetic composition and sequence diversity, and evaluated the data in the context of the pneumococcal population structure. RESULTS: We found that all genomes maintained a blp bacteriocin cassette and we identified several novel blp cassettes and genes. The composition of the bacteriocin/immunity region of the blp cassette was highly variable: one cassette possessed six bacteriocin genes and eight putative immunity genes, whereas another cassette had only one of each.

Animal circoviruses belong to the Circovirus genus of the Circoviridae family. Nowadays, only swine and birds were identified as circovirus hosts. Circoviruses have a single-stranded circular genome of approximately 2000 nucleotide long. DNA of these viruses possesses : (i) a nonanucleotide sequence essential for replication, flanked by inverted repeat sequences, a palindrome that has the potential to form a stem-loop structure and (ii) two major ORFs, located on the viral and complementary strands, which encode respectively the replication-associated protein (Rep) and the capsid protein (Cap). All the circoviruses described at the present time, except porcine circovirus of type 1, are associated with immunosuppressive or immunodepressive diseases. Histopathological lesions such as cytoplasmic inclusions of virus in histiocytic cells and T and B lymphocyte depletion in lymphoid organs, are commonly noticed. No medical prophylaxis of circovirus infections is currently available.. ...
The Duck circovirus (DuCV) is a type of virus found in ducks. Strains of the virus have predominantly been found in China, though strains have also been isolated from ducks in Germany and the United States. Duck circovirus is a small nonenveloped virus with a monomeric single-stranded circular DNA genome. DuCV has been clustered in the Circoviridae family genus Circovirus, according to the eighth report of the International Committee on Taxonomy of Viruses. Scientists have studied the Duck circovirus by using polymerase chain reaction (PCR)-based methods and dot blot hybridisation (DBH) tests. Infection with DuCV appears to cause growth disorders in ducks as well as eventual immunosuppression due to depletion of lymphatic cells. It was found that ducks between the ages of 40∼60 days were more susceptible to Duck circovirus. There was no evidence showing that the DuCV virus was capable of vertical transmission. The symptoms are immunosuppression, stunting in growth, and also feather ...

Cisplatin is the first-line chemotherapeutic drug for non-small cell lung cancer (NSCLC), and emerging evidences suggests that targeting circular RNAs (circRNAs) is an effective strategy to increase cisplatin-sensitivity in NSCLC, but the detailed mechanisms are still not fully delineated. Cell proliferation, viability and apoptosis were examined by using the cell counting kit-8 (CCK-8) assay, trypan blue staining assay and Annexin V-FITC/PI double staining assay, respectively. The expression levels of cancer associated genes were measured by using the Real-Time qPCR and Western Blot analysis at transcriptional and translated levels. Dual-luciferase reporter gene system assay was conducted to validated the targeting sites among hsa_circRNA_103809, miR-377-3p and 3′ untranslated region (3UTR) of GOT1 mRNA. The expression status, including expression levels and localization, were determined by immunohistochemistry (IHC) assay in mice tumor tissues. Here we identified a novel hsa_circRNA_103809/miR-377

The field of metagenomics has developed insight into many of the complex microbial communities responsible for maintaining life on this planet. Sequencing efforts often uncover novel genetic content; this is most evident for viral metagenomics, in which upwards of 90% of all sequences demonstrate no sequence similarity with present databases. For the small fraction which can be identified, the top BLAST hit is often posited as being representative of the phage taxon. However, as previous research has shown, the top BLAST hit is sometimes misinterpreted. Furthermore, the appearance of a particular gene homolog is frequently not representative of the presence of the particular taxon in question. To circumvent these limitations, we have developed a new method for the analysis of metaviromic datasets. BLAST hits are weighted, integrating the sequence identity and length of alignments as well as a phylogenetic signal. A genic rather than genomic approach is presented in which each gene is evaluated ...

IDENTIFICATION AND USE: Porcine circoviruses are small, icosahedral viruses that were discovered in 1974 as contaminants of a porcine kidney cell line. They were later called circoviruses when their genome was found to be a circular, single-stranded DNA molecule. Upon entry into cells, the viral ssDNA genome enters the nucleus where it is made double-stranded by host enzymes. It is then transcribed by host RNA polymerase II to form mRNAs that are translated into viral proteins. There is some evidence that circoviruses might have evolved from a plant virus that switched hosts and then recombined with a picorna-like virus.. Porcine circoviruses are classified in the Circoviridae family, which contains two genera, Circovirus and Gyrovirus. There are two porcine circoviruses, PCV-1 and PCV-2; only the latter causes disease in pigs. Infection probably occurs via oral and respiratory routes, and leads to various diseases including postweaning multisystemic wasting syndrome, and porcine dermatitis and ...
Baltimore Classification== ===Higher order taxa=== Viruses; ssDNA viruses; Circoviridae; Circovirus ===Species=== Beak and feather disease virus, Canary circovirus, Goose circovirus ==Description and Significance== Circoviruses are very small non-enveloped icosahedral viruses with a single stranded circular DNA genome. They have been described in pigs (porcine circovirus, PCV), chickens (chicken anemia virua, ChAV), psittacines (psittacine beak and feather disease virus, PBFD) and pigeons. The virus targets the lymphoid tissue and causes immunosuppression in the host. Circoviruses are the smallest pathogenic DNA viruses that have been identified and characterized in animals. ==Genome Structure== The genome of the circovirus is monomeric. It is unsegmented and contains a single molecule of circular, ambisense, sinle-stranded DNA that forms a covalently closed circle. The complete genome is 1800-2000 nucleotides long and the genome has a guanine+cytosine content of 48.4-53.1 %. (source: ...
Emerging viral infections can be identified by using a viral metagenomics approach for clinical human material. Diarrhea samples of patients with unexplained gastroenteritis from the Netherlands were analyzed by using viral metagenomics. Novel circular DNA viruses, bufaviruses, and genogroup III picobirnaviruses were identified. These data expand our knowledge of the human virome.
Dragonflies (Odonata) are one of the ancestral groups of extant insects. They represent one of the three most basal branches in the phylogeny of winged insects. The other two groups are the Ephemeroptera, mayflies, and Neoptera, the latter which covers the remaining winged insects. The first paper is about the phylogenetic position of Odonata in relation to the other basal insect clades using 18S and 28S rDNA sequences. It was demonstrated that there are under certain parameters a strong statistical support for a sister-group relationship between Odonata and Neoptera forming the group Palaeoptera. The second paper is about the phylogeny of the Holarctic dragonfly Leucorrhinia. Dragonfly larvae are frequently equipped with spines on the abdomen, with great variation in spinyness between species. From an analysis of sequences of ITS and 5.8S rDNA it was found that spines have been lost at least twice in Leucorrhinia, in the European L. rubicunda and again in a clade of North American species. The ...

Naiads will molt nine to 17 times before becoming adults (Corbet 1999). The number of generations per year depends on the species of odonate. Species at higher altitudes or in dry environments usually have one generation per year while those in tropical habitats may undergo multiple generations per year depending on the availability of appropriate habitats. When naiads are ready for their final molt they leave the water and crawl onto the bank or vegetation where they will molt into adults. Much like a caterpillar emerging from a chrysalis, they need to pump up their wings and allow their bodies to harden before they can be effective fliers. A newly emerged odonate is teneral (soft). A teneral dragonfly has glossy wings and the colors on the body are often pale. Several days after emerging and hardening completely, a dragonfly will have taken on the colors of an adult dragonfly. Adults: Identifying males and females is not difficult. Males will have what appears to be a pouch on the second and ...

Keywords: Airway epithelial civilizations, influenzavirus B, respiratory infections, VIDISCA-454, trojan discovery Launch The breakthrough of new viruses has been boosted in the last decade by high-throughput sequencing methods. These techniques can generate tens of thousands of sequence reads directly from a medical sample, and sequence alignment tools consequently can reveal the presence of previously unfamiliar viruses. The main limitation of these viral metagenomics techniques is that the detection of sequence reads derived from a viral genome does not necessarily indicate the disease is definitely pathogenic, in the absence of info on phenotypic properties such as infectivity, cell tropism, and the ability to induce the immune system.1 Once a new disease is identified, the fulfillment of Kochs postulates is needed to establish the part of the disease in disease. A disease tradition stage is definitely therefore needed to obtain relatively genuine disease shares for inoculation in an animal ...
Abundant bioinformatics resources are available for the study of complex microbial metagenomes, however their utility in viral metagenomics is limited. HoloVir is a robust and flexible data analysis pipeline that provides an optimized and validated workflow for taxonomic and functional characterization of viral metagenomes derived from invertebrate holobionts. Simulated viral metagenomes comprising varying levels of viral diversity and abundance were used to determine the optimal assembly and gene prediction strategy, and multiple sequence assembly methods and gene prediction tools were tested in order to optimize our analysis workflow. HoloVir performs pairwise comparisons of single read and predicted gene datasets against the viral RefSeq database to assign taxonomy and additional comparison to phage-specific and cellular markers is undertaken to support the taxonomic assignments and identify potential cellular contamination. Broad functional classification of the predicted genes is provided ...

When retroviruses have integrated their own genome into the germ line, their genome is passed on to a following generation. These endogenous retroviruses (ERVs), contrasted with exogenous ones, now make up 5-8% of the human genome.[7] Most insertions have no known function and are often referred to as "junk DNA". However, many endogenous retroviruses play important roles in host biology, such as control of gene transcription, cell fusion during placental development in the course of the germination of an embryo, and resistance to exogenous retroviral infection. Endogenous retroviruses have also received special attention in the research of immunology-related pathologies, such as autoimmune diseases like multiple sclerosis, although endogenous retroviruses have not yet been proven to play any causal role in this class of disease.[8] While transcription was classically thought to occur only from DNA to RNA, reverse transcriptase transcribes RNA into DNA. The term "retro" in retrovirus refers to ...
The hepatitis envelope proteins are composed of subunits made from the viral preS1, preS2, and S genes. The L (for "large") envelope protein contains all three subunits. The M (for "medium") protein contains only preS2 and S. The S (for "small") protein contains only S. The genome portions encoding these envelope protein subuntis share both the same frame and the same stop codon (generating nested transcripts on a single open reading frame. The pre-S1 is encoded first (closest to the 5' end), followed directly by the pre-S2 and the S. When a transcript is made from the beginning of the pre-S1 region, all three genes are included in the transcript and the L protein is produced. When the transcript starts after the pro-S1 at the beginning of the pre-S2 the final protein contains the pre-S2 and S subunits only and therefore is an M protein. The smallest envelope protein containing just the S subunit is made most because it is encoded closest to the 3' end and comes from the shortest transcript. ...
Viruses in Betanodavirus are non-enveloped, with icosahedral geometries, and T=3 symmetry. The diameter is around 30 nm. Genomes are linear and segmented, bipartite, around 21.4kb in length.[8]. The crystal structure of a betanodavirus- T=3 Grouper nervous necrosis virus (GNNV)-like particle has been determined by X-ray crystallography. The virus-like particle contains 180 subunits of the capsid protein, and each capsid protein (CP) shows three major domains: (i) the N-terminal arm, an inter-subunit extension at the inner surface; (ii) the shell domain (S-domain), a jelly-roll structure; and (iii) the protrusion domain (P-domain) formed by three-fold trimeric protrusions. [10]. ...
Nucleic acid analysis suggests a very long association of the viruses with the wasps (greater than 70 million years).. Two proposals have been advanced for how the wasp/virus association developed. The first suggests that the virus is derived from wasp genes. Many parasitoids that do not use PDVs inject proteins that provide many of the same functions, that is, a suppression of the immune response to the parasite egg. In this model, the braconid and ichneumonid wasps packaged genes for these functions into the viruses-essentially creating a gene-transfer system that results in the caterpillar producing the immune-suppressing factors. In this scenario, the PDV structural proteins (capsids) were probably "borrowed" from existing viruses.. The alternative proposal suggests that ancestral wasps developed a beneficial association with an existing virus that eventually led to the integration of the virus into the wasp's genome. Following integration, the genes responsible for virus replication and the ...
The Herpesvirales naming system originated in 1973 and has been elaborated considerably since. All herpesviruses described since this system was adopted have been named in accordance with it. The recommended naming system specifies that each species name consists of three parts: a first word, a second word, and finally a number. The first word should be derived from the taxon (family or subfamily) to which its primary natural host belongs. The subfamily name is used for viruses from members of the family Bovidae or from primates (the virus name ending in -ine, e.g. bovine), and the host family name for other viruses (ending in -id, e.g. equid). Human herpesviruses have been treated as an exception (human rather than hominid). Following the host-derived term, species in the family Herpesviridae, which are divided into subfamilies Alphaherpesvirinae, Betaherpesvirinae, and Gammaherpesvirinae, will have the word alphaherpesvirus, betaherpesvirus, or gammaherpesvirus added, respectively. Species in ...
