Bocaparvovirus
''Bocaparvovirus'' is a genus of viruses in the subfamily ''Parvovirinae'' of the virus family ''Parvoviridae''. Humans, cattle, and dogs serve as natural hosts. There are 28 species in this genus. Diseases associated with this genus include, in humans, acute respiratory illness, and in cattle, diarrhea and mild respiratory symptoms. History Bocaviruses were first described in animals in the early 1960s. Genome Like the other members of this family, bocaparvoviruses have two open reading frames—ORF1 and 2. Unique among parvoviruses, the bocaparvoviruses contain a third open reading frame between non-structural and structural coding regions. This gene encodes a highly phosphorylated nonstructural protein (NP1). ORF1 encodes a nonstructural protein (NS1) that is involved in viral genome replication. ORF2 encodes the two capsid proteins—VP1 and VP2. Like other parvoviruses, the VP1 unique region contains a phospholipase A(2) motif with a conserved Histidine– Aspartic acid-X ...

Carnivore Bocaparvovirus 1
''Carnivore bocaparvovirus 1'', formerly ''Canine minute virus'' (or minute virus of canines; MVC) 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. In experimental infections, the virus is spread transplacentally when the dam is infected between 25 and 30 days of gestation and can result in abortion. When the dam is infected between 30 and 35 days, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ungulate Bocaparvovirus 1
''Ungulate bocaparvovirus 1'', formerly ''Bovine parvovirus'' (BPV), also known as Haemadsorbing enteric Virus, is a member of the parvovirus group, with three significant sub-species: BPV1, 2 and 3. BPV most commonly causes diarrhea in neonatal calves and respiratory and reproductive disease in adult cattle. The distribution of the virus is worldwide. Transmission is both vertical (transplacental route) and horizontal ( oro-fecal route). The virus is very resistant to chemical and physical challenges. Clinical signs and diagnosis Diarrhea is often the only clinical sign in neonatal calves. Reproductive infection causes abortion and the birth of weak or stillborn calves. Respiratory signs such as coughing, dyspnea, and nasal discharge also can occur. The clinical signs of BPV may be made worse by concurrent GI infections. Immunofluorescence (IF), PCR, hemagglutination, ELISA and electron microscopy can be used to identify the virus. Aborted fetuses are edematous and have i ...

Parvoviridae
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. Parvoviruses enter a host cell by endocytosis, travelling to the nucleus where they wait until the cell enters its replication stage. At that point, the genome is uncoated and the coding portion is replicated. Viral messenger RNA (mRNA) is then transcribed and translated, resulting in NS1 initiating replication. During replication, the hairpins repeatedly unfold, are replicated, and refold to chang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Primate Bocaparvovirus 3
Primates are a diverse order of mammals. They are divided into the strepsirrhines, which include the lemurs, galagos, and lorisids, and the haplorhines, which include the tarsiers and the simians ( monkeys and apes, the latter including humans). Primates arose 85–55 million years ago first from small terrestrial mammals, which adapted to living in the trees of tropical forests: many primate characteristics represent adaptations to life in this challenging environment, including large brains, visual acuity, color vision, a shoulder girdle allowing a large degree of movement in the shoulder joint, and dextrous hands. Primates range in size from Madame Berthe's mouse lemur, which weighs , to the eastern gorilla, weighing over . There are 376–524 species of living primates, depending on which classification is used. New primate species continue to be discovered: over 25 species were described in the 2000s, 36 in the 2010s, and three in the 2020s. Primates have large ...

Pinniped Bocaparvovirus 1
Pinnipeds (pronounced ), commonly known as seals, are a widely range (biology), distributed and diverse clade of carnivorous, fin-footed, semiaquatic, mostly marine mammal, marine mammals. They comprise the extant taxon, extant family (biology), families Odobenidae (whose only living member is the walrus), Otariidae (the eared seals: sea lions and fur seals), and Phocidae (the earless seals, or true seals). There are 34 extant species of pinnipeds, and more than 50 extinct species have been described from fossils. While seals were historically thought to have descended from two ancestral lines, molecular phylogenetics, molecular evidence supports them as a monophyletic lineage (descended from one ancestral line). Pinnipeds belong to the order Carnivora; their closest living relatives are Musteloidea, musteloids (Mustelidae, weasels, Procyonidae, raccoons, skunks, and red pandas), having diverged about 50 million years ago. Seals range in size from the and Baikal sea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
