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] |

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 ...

Protoparvovirus
''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).

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.

Canine Parvovirus
Canine parvovirus (also referred to as CPV, CPV2, or parvo) is a contagious virus mainly affecting dogs. CPV is highly contagious and is spread from dog to dog by direct or indirect contact with their feces. Vaccines can prevent this infection, but mortality can reach 91% in untreated cases. Treatment often involves veterinary hospitalization. Canine parvovirus often infects other mammals including foxes, wolves, cats, and skunks. Felines (cats) are also susceptible to panleukopenia, a different strain of parvovirus. Signs Dogs that develop the disease show signs of the illness within three to ten days. The signs may include lethargy, vomiting, fever, and diarrhea (usually bloody). Generally, the first sign of CPV is lethargy. Secondary signs are loss of weight and appetite or diarrhea followed by vomiting. Diarrhea and vomiting result in dehydration that upsets the electrolyte balance and this may affect the dog critically. Secondary infections occur as a result of the weaken ...
