The rhinovirus is the most common viral infectious agent in humans and is the predominant cause of the common cold. Rhinovirus infection proliferates in temperatures of 33–35 °C (91–95 °F), the temperatures found in the nose. Rhinoviruses belong to the genus Enterovirus in the family Picornaviridae.
Parvoviruses are a family of animal viruses that constitute the family Parvoviridae. They have linear, single-stranded DNA (ssDNA) genomes that typically contain two genes encoding for a replication initiator protein, called NS1, and the protein the viral capsid is made of. The coding portion of the genome is flanked by telomeres at each end that form into hairpin loops that are important during replication. Parvovirus virions are small compared to most viruses, at 23–28 nanometers in diameter, and contain the genome enclosed in an icosahedral capsid that has a rugged surface.
Picornaviruses are a group of related nonenveloped RNA viruses which infect vertebrates including fish, mammals, and birds. They are viruses that represent a large family of small, positive-sense, single-stranded RNA viruses with a 30 nm icosahedral capsid. The viruses in this family can cause a range of diseases including the common cold, poliomyelitis, meningitis, hepatitis, and paralysis.
Primate erythroparvovirus 1, generally referred to as B19 virus(B19V),parvovirus B19 or sometimes erythrovirus B19, is the first known human virus in the family Parvoviridae, genus Erythroparvovirus; it measures only 23–26 nm in diameter. The name is derived from Latin, parvum meaning small, reflecting the fact that B19 ranks among the smallest DNA viruses. B19 virus is most known for causing disease in the pediatric population; however, it can also affect adults. It is the classic cause of the childhood rash called fifth disease or erythema infectiosum, or "slapped cheek syndrome".
Aphthovirus is a viral genus of the family Picornaviridae. Aphthoviruses infect split-hooved animals, and include the causative agent of foot-and-mouth disease, Foot-and-mouth disease virus (FMDV). There are seven FMDV serotypes: A, O, C, SAT 1, SAT 2, SAT 3 and Asia 1, and four non-FMDV serotypes belonging to three additional species Bovine rhinitis A virus (BRAV), Bovine rhinitis B virus (BRBV) and Equine rhinitis A virus (ERAV).
Amdoparvovirus is a genus of viruses in the family Parvoviridae in the subfamily Parvovirinae. Mustelids, skunk, and raccoons serve as natural hosts. There are five species in this genus. Diseases associated with this genus include progressive disorder of immune system.
Carnivore bocaparvovirus 1, formerly Canine minute virus is a species of Bocaparvovirus of the family Parvoviridae that infects dogs. It is similar to bovine parvovirus in its protein structure and DNA. A virus causing respiratory disease in humans has been called human bocavirus due to its similarity to these viruses. Canine minute virus was originally discovered in Germany in 1967 in military dogs, although it was originally thought to not cause disease. Dogs and puppies are infected orally, and the virus is spread transplacentally to the fetuses. Symptoms are seen most commonly between the ages of one to three weeks and include severe diarrhea, difficulty breathing, and anorexia. In severe cases, illness can be fatal.
Dependoparvovirus is a genus in the subfamily Parvovirinae of the virus family Parvoviridae; they are Group II viruses according to the Baltimore classification. Some dependoparvoviruses are also known as adeno-associated viruses because they cannot replicate productively in their host cell without the cell being coinfected by a helper virus such as an adenovirus, a herpesvirus, or a vaccinia virus.
Human bocavirus (HBoV) is the name given to all viruses in the genus Bocaparvovirus of virus family Parvoviridae that are known to infect humans. HBoV1 and HBoV3 are members of species Primate bocaparvovirus 1 whereas viruses HBoV2 and HBoV4 belong to species Primate bocaparvovirus 2. Some of these viruses cause human disease. HBoV1 is strongly implicated in causing some cases of lower respiratory tract infection, especially in young children, and several of the viruses have been linked to gastroenteritis, although the full clinical role of this emerging infectious disease remains to be elucidated.
Erythroparvovirus is a genus of viruses in subfamily Parvovirinae of the virus family Parvoviridae. Primates serve as natural hosts. There are seven species in this genus. Diseases associated with this genus include fifth disease and skin lesions.
Densovirinae is a subfamily of single-stranded DNA viruses in the family Parvoviridae. The subfamily has 11 recognized genera and 21 species. Densoviruses are known to infect members of insect orders Blattodea, Diptera, Hemiptera, Hymenoptera, Lepidoptera, and Orthoptera, while some viruses infect and multiply in crustaceans such as shrimp or crayfish, or sea stars from phylum Echinodermata.
Tetraparvovirus are a genus of viruses in the family Parvoviridae. There are six recognized species: Chiropteran tetraparvovirus 1, Primate tetraparvovirus 1, Ungulate tetraparvovirus 1, Ungulate tetraparvovirus 2, Ungulate tetraparvovirus 3, and Ungulate tetraparvovirus 4.
Bidensovirus is a genus of single stranded DNA viruses that infect invertebrates. The species in this genus were originally classified in the family Parvoviridae but were moved to a new genus because of significant differences in the genomes.
Minute virus of mice (MVM) is the exemplar virus of the species Rodent protoparvovirus 1, in the genus Protoparvovirus of the Parvoviridae family of viruses. MVM exists in multiple variant forms including MVMp, which is the prototype strain that infects cells of fibroblast origin, while MVMi, the immunosuppressive strain, infects T lymphocytes. MVM is a common infection in laboratory mice due to its highly contagious nature. The virus can be shed from infected mice via feces and urine, but also via fomites and nasal secretions. Typically there are no clinical signs of infection in adult mice, however, experimental infection can cause multiple organ damage during fetal development or shortly after birth.
Protoparvovirus is a genus of viruses in the Parvovirinae subfamily of the virus family Parvoviridae. Vertebrates serve as natural hosts. There are 15 species in the genus including Rodent protoparvovirus 1 for which the exemplar virus is minute virus of mice (MVM). This genus also includes canine parvovirus (CPV), which causes gastrointestinal tract damage in puppies that is about 80% fatal, and porcine parvovirus (PPV), which is a major cause of fetal death and infertility in pigs. The genus divides phylogenetically into two branches, one that contains many founder members of the family, such as MVM, CPV and PPV, which have been studied in considerable detail, and a second branch occupied exclusively by predicted viruses whose coding sequences were identified recently in the wild using virus discovery approaches, but whose biology remains minimally explored. This second branch currently contains two species whose members infect humans, called Primate protoparvovirus 1 and Primate protoparvovirus 3. Until 2014, the genus was called Parvovirus, but it was renamed to eliminate confusion between members of this genus and members of the entire family Parvoviridae.
Brevihamaparvovirus is a genus of viruses in subfamily Hamaparvovirinae of the family Parvoviridae. Mosquitoes serve as natural hosts. There are two species in this genus.
Aveparvovirus is a genus of viruses, in the subfamily Parvovirinae of the virus family Parvoviridae. There are three species in this genus. Diseases associated with this genus include: enteric disease and malabsorption syndrome.
Copiparvovirus is a genus of viruses in subfamily Parvovirinae of the virus family Parvoviridae. Pigs and cows are known to serve as natural hosts. There are seven species in this genus.
Penstylhamaparvovirus is the name of a genus of viruses in the subfamily Hamaparvovirinae of the virus family Parvoviridae. Shrimps and insects serve as natural hosts. There is only one species in this genus: Decapod penstylhamaparvovirus 1.
Astroviridae is a family of non-enveloped ssRNA viruses that cause infections in different animals. The family name is derived from the Greek word astron ("star") referring to the star-like appearance of spikes projecting from the surface of these small unenveloped viruses. Astroviruses were initially identified in humans but have since been isolated from other mammals and birds. This family of viruses consists of two genera, Avastrovirus (AAstV) and Mamastrovirus (MAstV). Astroviruses most frequently cause infection of the gastrointestinal tract but in some animals they may result in encephalitis, hepatitis (avian) and nephritis (avian).
