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.
calibration (kal´

2. the comparison of procedures between clinicians to achieve a clinical standard.

Caliciviridae
n a grouping of nonenveloped, 20-sided RNA viruses, and includes the Norwalk gastroenteritis virus.
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.
