Cal·i·ci·vi·ri·dae

(kal'i-sī-vī'ră-dē),
A family of naked icosahedral single-stranded positive sense RNA viruses 30-38 mm in diameter associated with epidemic viral gastroenteritis and certain forms of hepatitis in humans.

Caliciviridae

/Ca·li·ci·vi·ri·dae/ (kah-lis″ĭ-vir´ĭ-de) the caliciviruses: a family of RNA viruses having a positive-sense, single-stranded RNA genome, and transmitted via infested food, by contact, or by airborne particles. The single genus is Calicivirus.

Caliciviridae

[kalis′ivir′idē]
a family of plus-stranded ribonucleic acid viruses that have a nonenveloped virion 35 to 40 nm in diameter. It is associated with episodes of gastroenteritis and upper respiratory infection in humans and animals, including exanthema in swine.

Cal·i·ci·vi·ri·dae

(kal'i-sē-vir'i-dē)
A family of RNA viruses associated with epidemic viral gastroenteritis and some forms of hepatitis.

Cal·i·ci·vi·ri·dae

(kal'i-sē-vir'i-dē)
A family of RNA viruses associated with epidemic viral gastroenteritis and some forms of hepatitis.

Caliciviridae

a family of viruses that are about 35 nm in diameter, with a capsid, composed of a single major capsid protein of about 60 kilodaltons that carries 32 shallow, cup-like circular indentations and a single-stranded, plus sense RNA genome of about 8 kilobases. The family comprises four genera, Vesivirus that includes feline calicivirus, vesicular exanthema of swine virus, and San Miguel sealion virus, Lagovirus that includes rabbit hemorrhagic disease virus and European Brown hare syndrome virus, Norovirus, a cause of gastroenteritis in humans, and Sapovirus which comprise viruses that primarily cause diarrheic infections in humans and some other animal species.

289, yielded a novel mammalian virus from the family Caliciviridae that we further characterized by near full-length genome sequencing using random amplification with next-generation sequencing, specific reverse transcription PCRs, and 3' rapid amplification of cDNAends PCR (Figure 1, panel A) as described (6,7).
The Caliciviridae genome encodes a polyprotein precursor for nonstructural proteins, and 2 structural capsid proteins, viral protein (VP) 1 and VP2, from 2 or 3 open reading frames (ORFs) (Figure 1, panel B) (8,9).
Although no species demarcation criteria have been defined for the family Caliciviridae by the International Committee on the Taxonomy of Viruses, we classified calicivirus Bangladesh/289/2007 in the proposed genus Recovirus, primarily on the basis of phylogenetic analyses (5).
Complete genomes of strains representing different Caliciviridae genera were selected for a phylogenetic tree (Figure 1).
Given the capsid analyses, the new Nebovirus genus in the Caliciviridae family should thus comprise 2 genotypes: one would include the reference strains Bo/Nebraska/80/US and Bo/Newbury1/76/UK and the second would include Bo/DijonA216/06/FR.
Genomic characterization of the unclassified bovine enteric virus Newbury agent-1 (Newbury1) endorses a new genus in the family Caliciviridae.
The name of these members of the Caliciviridae family of nonenveloped RNA viruses reflects their structure.
