Characterization of a highly divergent TT virus genome. (1/138)

A novel TT virus (TTV)-like DNA sequence was detected in the serum of a patient (PM) with acute non-A-E hepatitis. The full-length genome sequence, referred to here as PM virus (PMV), was obtained and its relationship to other full or near full-length TTV sequences examined. Although it shares a common genomic arrangement and short conserved regions, the majority of the genome is extremely divergent, displaying an average genetic distance of 0.60 from all other TTV sequences. By comparing PMV with TTV genomes representing the most divergent types so far described, six major groups can be distinguished. The level of genetic diversity seen between these genomes is higher than would be expected within a single virus species. Indeed, PMV could be considered the prototype of an independent taxonomic group within the Circoviridae: family. A genoprevalence study of sera from blood donors and patients with acute hepatitis suggests that PMV is rare. (+info)

Three spliced mRNAs of TT virus transcribed from a plasmid containing the entire genome in COS1 cells. (2/138)

A permuted whole-genome construct of a TT virus (TTV), named VT416, had 3,852 nucleotides (nt) 98.2% similar to the prototype TA278 genome. To allow the transcription of TTV from the internal promoter, pBK*VT416(1.3G), carrying 1.3 units of VT416, was constructed. The poly(A)(+) RNAs expressed in COS1 cells 48 h posttransfection contained three TTV mRNA species 3.0, 1.2, and 1.0 kb in length, which were recovered in the 13 DNA clones from a lambda phage cDNA library. These mRNAs in the antigenomic orientation possessed in common the 3' terminus downstream of a poly(A) signal (A(3073)ATAAA) and the 5' terminus downstream of a cap site (C(98)ACTTC). A common splicing to join nt 185 with nt 277 was detected in all mRNAs. The coding region of the largest open reading frame (ORF) was maintained in 3.0-kb mRNA, because this splicing was located upstream of its initiation codon (A(589)TG). The second splicing was detected in 1.2-kb mRNA to join nt 711 with nt 2374 and in 1.0-kb mRNA to bind nt 711 to nt 2567. They linked a proposed ORF2 to another ORF for creating new ORFs over nt 2374 to 2872 in frame 2 and nt 2567 to 3074 in frame 3. The donor and acceptor sites of all three splicings matched the consensus sequence and were conserved in most of the 16 TTVs of distinct genotypes retrieved from the database. The observed transcription profile is unique to TTV among known members in the family Circoviridae. (+info)

Sequestration of TT virus of restricted genotypes in peripheral blood mononuclear cells. (3/138)

Peripheral blood mononuclear cells (PBMC) harbored TT virus (TTV) of genotypes (3 and 4) different from those (1 and 2) of free virions in plasma of the same individuals. PBMC may act as a reservoir, and TTV of particular genotypes might have tropism for hematopoietic cells. (+info)

Detection rates of TT virus DNA in serum of umbilical cord blood, breast milk and saliva. (4/138)

To date, the routes of mother-to-infant transmission of TT virus (TTV) have not been fully elucidated. The present study examines the detection rates of TTV DNA in the serum of pregnant Japanese women and in cord blood at the time of delivery, as well as in the saliva and breast milk of mothers one-month postpartum. Primers derived from the well-known translated region N22 (N22 system), as well as the untranslated region (UTR system) were used. The prevalence of TTV DNA in the serum of pregnant women was found to be 11.9% (19/160) using the N22 system and 72.4% (55/76) using the UTR system. No TTV DNA was detected in the cord blood samples (0/160) when the N22 system was used for detection but TTV DNA was detected in 11.8% (7/76) of samples studied with the UTR system. Using the N22 system, TTV DNA was not detected in breast milk, but was detected in saliva. However using the UTR system, TTV DNA was detected in both specimens. These results imply that some babies are vertically infected with TTV via cord blood at the time of delivery or via breast milk or saliva. However, further research is necessary to confirm this hypothesis. polymerase chain reaction; pregnant women; horizontal route of transmission (+info)

TT virus infection in Japanese children: isolates from genotype 1 are overrepresented in patients with hepatic dysfunction of unknown etiology. (5/138)

The pathogenecity of the TT virus (TTV) especially during childhood remains obscure. We investigated the prevalence of TTV in 40 patients with non-A to C hepatic dysfunction (non-A to C hepatic dysfunction group). Five patients with fulminant hepatitis of unknown etiology were enrolled in this group. We also examined 380 children without a history of transfusion or liver disease (control group). Subsequently, the genotypes of TTV strains isolated were analyzed in terms of their nucleotide sequences including 222 bp in the open reading frame 1 region. The prevalence of serum TTV DNA was 10/40 (25%) in the non-A to C hepatic dysfunction group and 25/380 (7%) in the control group. Sixty-six percent (23/35) of all examined cases exhibited either genotype 1 or 2. However, assessment of genotype in the non-A to C hepatic dysfunction group (10 cases) revealed a higher prevalence of genotype 1 than of all other genotypes (80% vs. 20%). This result differed significantly from that of the control group (25 cases; 32% vs. 68%). Such overrepresentation of genotype 1 suggests that this type of TTV strain is associated with the development of hepatic dysfunction of unknown etiology in Japanese children. (+info)

Fecal excretion of a novel human circovirus, TT virus, in healthy children. (6/138)

The role of TT virus (TTV) as a human pathogen is unclear, as is the mode of TTV transmission. To determine the prevalence of TTV infection and the possible fecal-oral route of transmission, we analyzed fecal specimens from 67 healthy, nontransfused children for TTV DNA sequences by heminested PCR, using the NG and T primer sets. The overall prevalence of TTV fecal excretion was 22.4% (15 of 67), with the T primer set (19.4%) being more sensitive than the NG primer set (10.4%). TTV prevalence based on gender or ethnicity showed no significant differences. None of seven children in the 0- to 6-month age group had detectable TTV in feces. Of three sets of siblings, two unrelated sets of twins, ages 33 and 37 months, were negative for fecal TTV DNA, while the third set of siblings, ages 99 and 35 months, was positive. The absence of TTV in the feces of children younger than 6 months and the high prevalence (40%) in children 7 to 12 months of age is consistent with age-specific acquisition of TTV infection by the nonparenteral route. TTV genotypes 1, 3, 4, and 5 were represented in our study population. TTV-positive siblings had TTV genotypes 1 and 4, suggesting unrelated environmental sources of TTV infection. This observation suggests a possible time frame for TTV acquisition in children which coincides with increased interaction with their environment and increased susceptibility to infectious agents.

Full-length nucleotide sequence of a simian TT virus isolate obtained from a chimpanzee: evidence for a new TT virus-like species. (7/138)

Recently, we identified TT virus (TTV) isolates from nonhuman primates and named them simian TTV (s-TTV). To characterize the genomic structure of these isolates in more detail, the full-length nucleotide sequence of the s-TTV isolate (designated s-TTV CH65-1), recovered from a chimpanzee born in West Africa, was amplified by nested PCR with inverted primers deduced from the untranslated region of s-TTV DNA. CH65-1 was composed of 3899 nucleotides (nt) and had two open reading frames (ORF) spanning 2295 nt (ORF1) and 402 nt (ORF2). The sequence had only 52.3% similarity to the prototype TA278 human isolate. Phylogenetic analysis demonstrated that CH65-1 was distinct from the human TTV isolates. These results suggested that s-TTV may represent a new TTV-like viral species or genus. (+info)

Species-specific TT viruses in humans and nonhuman primates and their phylogenetic relatedness. (8/138)

By means of polymerase chain reaction with a primer pair (NG133-NG147) deduced from the untranslated region (UTR) of TT virus (TTV), TTVs with markedly distinct genomic lengths were recovered from sera of humans and nonhuman primates, and their entire nucleotide sequences were determined. A human TTV [TGP96 of 2908 nucleotides (nt)] was obtained that was about 900 nt shorter than heretofore reported TTVs (3787-3853 nt). Likewise, TTVs of chimpanzee occurred in two distinct genomic sizes [Pt-TTV6 (3690 nt) and Pt-TTV8-II (2785 nt)]. Two TTVs of Japanese macaque [Mf-TTV3 (3798 nt) and Mf-TTV9 (3763 nt)] were comparable in genomic length, but only 55% similar in sequence. These five human and nonhuman primate TTVs, along with TTVs of tamarin [So-TTV2 (3371 nt)] and douroucouli [At-TTV3 (3718 nt)], were compared over the entire nucleotide sequence. Although the seven TTVs were only < or = 55% similar, they share a common genomic organization with two open reading frames (ORFs), designated ORF1 (654-735 amino acids) and ORF2 (91-152 amino acids). The N-terminal sequences of ORF1 proteins were rich in arginine, and sequence motifs necessary for transcription and replication were conserved among them all. Like the human prototype TTV (TA278), all seven TTVs from various animals possessed in common two 15-nt sequences (CGAATGGCTGAGTTT and AGGGGCAATTCGGGC) in the UTR that were covered by NG133 and NG147, respectively. These primers would be instrumental in research on TTVs in previously unexamined species for defining their virological characteristics and evolutionary relationships. (+info)

Torque teno virus (TTV) is a single-stranded DNA virus that belongs to the family Anelloviridae. It was first identified in 1997 and has since been found to be present in the majority of human populations worldwide. The virus is classified into several genotypes and subtypes, with TTV being the prototype member of the genus Alphainellovirus.

TTV is a small virus, measuring only about 30-40 nanometers in diameter. It has a circular genome that ranges in size from 2.8 to 3.9 kilobases and encodes for several non-structural proteins involved in viral replication. The virus does not appear to cause any specific disease symptoms, but it has been associated with various clinical conditions such as liver disease, respiratory tract infections, and cancer.

TTV is primarily transmitted through the fecal-oral route, although other modes of transmission have also been suggested, including saliva, blood, and vertical transmission from mother to child during pregnancy or delivery. The virus has been detected in various body fluids, tissues, and organs, including blood, stool, respiratory secretions, and the liver.

The clinical significance of TTV infection remains unclear, as it is frequently found in both healthy individuals and those with various diseases. However, some studies have suggested that TTV viral load or genotype may be associated with certain clinical conditions, such as liver disease, transplant rejection, and cancer. Further research is needed to better understand the role of TTV in human health and disease.

DNA virus infections refer to diseases or conditions caused by the invasion and replication of DNA viruses in a host organism. DNA viruses are a type of virus that uses DNA as their genetic material. They can cause a variety of diseases, ranging from relatively mild illnesses to severe or life-threatening conditions.

Some examples of DNA viruses include herpes simplex virus (HSV), varicella-zoster virus (VZV), human papillomavirus (HPV), hepatitis B virus (HBV), and adenoviruses. These viruses can cause a range of diseases, including cold sores, genital herpes, chickenpox, shingles, cervical cancer, liver cancer, and respiratory infections.

DNA virus infections typically occur when the virus enters the body through a break in the skin or mucous membranes, such as those found in the eyes, nose, mouth, or genitals. Once inside the body, the virus infects cells and uses their machinery to replicate itself, often causing damage to the host cells in the process.

The symptoms of DNA virus infections can vary widely depending on the specific virus and the severity of the infection. Treatment may include antiviral medications, which can help to reduce the severity and duration of symptoms, as well as prevent the spread of the virus to others. In some cases, vaccines may be available to prevent DNA virus infections.

"Torque" is not a term that has a specific medical definition. It is a physical concept used in the fields of physics and engineering, referring to a twisting force that causes rotation around an axis. However, in certain medical contexts, such as in discussions of spinal or joint biomechanics, the term "torque" may be used to describe a rotational force applied to a body part. But generally speaking, "torque" is not a term commonly used in medical terminology.

Anellovirus is a type of small, single-stranded DNA virus that infects humans and animals. These viruses are classified in the family Anelloviridae and include several genera such as Torque teno virus (TTV), Torque teno mini virus (TTMV), and Torque teno midi virus (TTMDV).

Anelloviruses are widespread and found in various body fluids, including blood, saliva, and stool. They are believed to be transmitted through close contact with infected individuals or through contaminated food and water. Although anelloviruses have been detected in people with various diseases, their role in human health and disease remains unclear.

In immunocompromised individuals, such as those with HIV/AIDS or organ transplant recipients, anellovirus infections can become persistent and may be associated with adverse health outcomes. However, more research is needed to fully understand the clinical significance of these viruses.

Water purification is the process of removing or reducing contaminants in water to make it safe and suitable for specific uses, such as drinking, cooking, irrigation, or medical purposes. This is typically achieved through physical, chemical, or biological methods, or a combination thereof. The goal is to eliminate or reduce harmful substances like bacteria, viruses, parasites, heavy metals, pesticides, and other pollutants that can cause illness or negatively impact human health, aquatic life, or the environment.

The specific purification methods used may vary depending on the nature of the contaminants and the desired level of purity for the intended use. Common techniques include filtration (using various types of filters like activated carbon, ceramic, or reverse osmosis), disinfection (using chemicals like chlorine or UV light to kill microorganisms), sedimentation (allowing particles to settle and be removed), and distillation (heating water to create steam, which is then condensed back into pure water).

A viral genome is the genetic material (DNA or RNA) that is present in a virus. It contains all the genetic information that a virus needs to replicate itself and infect its host. The size and complexity of viral genomes can vary greatly, ranging from a few thousand bases to hundreds of thousands of bases. Some viruses have linear genomes, while others have circular genomes. The genome of a virus also contains the information necessary for the virus to hijack the host cell's machinery and use it to produce new copies of the virus. Understanding the genetic makeup of viruses is important for developing vaccines and antiviral treatments.

Viral DNA refers to the genetic material present in viruses that consist of DNA as their core component. Deoxyribonucleic acid (DNA) is one of the two types of nucleic acids that are responsible for storing and transmitting genetic information in living organisms. Viruses are infectious agents much smaller than bacteria that can only replicate inside the cells of other organisms, called hosts.

Viral DNA can be double-stranded (dsDNA) or single-stranded (ssDNA), depending on the type of virus. Double-stranded DNA viruses have a genome made up of two complementary strands of DNA, while single-stranded DNA viruses contain only one strand of DNA.

Examples of dsDNA viruses include Adenoviruses, Herpesviruses, and Poxviruses, while ssDNA viruses include Parvoviruses and Circoviruses. Viral DNA plays a crucial role in the replication cycle of the virus, encoding for various proteins necessary for its multiplication and survival within the host cell.

"Swine" is a common term used to refer to even-toed ungulates of the family Suidae, including domestic pigs and wild boars. However, in a medical context, "swine" often appears in the phrase "swine flu," which is a strain of influenza virus that typically infects pigs but can also cause illness in humans. The 2009 H1N1 pandemic was caused by a new strain of swine-origin influenza A virus, which was commonly referred to as "swine flu." It's important to note that this virus is not transmitted through eating cooked pork products; it spreads from person to person, mainly through respiratory droplets produced when an infected person coughs or sneezes.

Polymerase Chain Reaction (PCR) is a laboratory technique used to amplify specific regions of DNA. It enables the production of thousands to millions of copies of a particular DNA sequence in a rapid and efficient manner, making it an essential tool in various fields such as molecular biology, medical diagnostics, forensic science, and research.

The PCR process involves repeated cycles of heating and cooling to separate the DNA strands, allow primers (short sequences of single-stranded DNA) to attach to the target regions, and extend these primers using an enzyme called Taq polymerase, resulting in the exponential amplification of the desired DNA segment.

In a medical context, PCR is often used for detecting and quantifying specific pathogens (viruses, bacteria, fungi, or parasites) in clinical samples, identifying genetic mutations or polymorphisms associated with diseases, monitoring disease progression, and evaluating treatment effectiveness.

Phylogeny is the evolutionary history and relationship among biological entities, such as species or genes, based on their shared characteristics. In other words, it refers to the branching pattern of evolution that shows how various organisms have descended from a common ancestor over time. Phylogenetic analysis involves constructing a tree-like diagram called a phylogenetic tree, which depicts the inferred evolutionary relationships among organisms or genes based on molecular sequence data or other types of characters. This information is crucial for understanding the diversity and distribution of life on Earth, as well as for studying the emergence and spread of diseases.

Parvovirus, Porcine (PPV) is a single-stranded DNA virus that belongs to the family Parvoviridae and genus Parvovirus. It is a small, non-enveloped virus that primarily infects the rapidly dividing cells of piglets, particularly those in the intestinal epithelium and bone marrow.

PPV infection can cause a variety of clinical signs, including diarrhea, vomiting, lethargy, and loss of appetite, which can lead to severe dehydration and death in young piglets. The virus is highly contagious and can be spread through fecal-oral transmission or by ingesting infected material.

PPV infection is also associated with reproductive failure in sows, including stillbirths, mummified fetuses, and weak newborn piglets. This condition is known as Porcine Parvovirus Syndrome (PPVS). The virus can cross the placenta and infect developing fetuses, causing damage to their cardiovascular and nervous systems.

There are currently no specific treatments for PPV infection, but vaccination programs have been developed to prevent the spread of the virus in pig herds. Good biosecurity practices, such as isolating infected animals and thoroughly cleaning and disinfecting facilities, can also help reduce the risk of transmission.

Porcine Postweaning Multisystemic Wasting Syndrome (PPWS) is not a widely recognized or officially established medical term in human healthcare. However, it is a significant disease in swine (pig) farming. Here's the definition of PPWS from a veterinary medicine perspective:

Porcine Postweaning Multisystemic Wasting Syndrome (PPWS) is a complex and poorly understood disease affecting piglets after weaning. The syndrome is characterized by wasting, diarrhea, and various secondary symptoms impacting multiple body systems. The primary cause of PPWS remains elusive, but it is believed to be associated with a combination of infectious agents (such as viruses and bacteria) and non-infectious factors (like management practices, environmental conditions, and genetics). The disease has a significant economic impact on the swine industry due to reduced growth rates, increased mortality, and decreased feed conversion efficiency in affected piglets.
