Calici- comes from the Latin word Calyx and the Greek word kalyx. The words mean a cup or chalice, a Calix. This comes from the strains having visible cup-shaped depressions.
The following genera are recognized: 1. Bavovirus 2. Lagovirus 3. Minovirus 4. Nacovirus 5. Nebovirus 6. Norovirus 7. Recovirus 8. Salovirus 9. Sapovirus 10. Valovirus 11. Vesivirus A number of other caliciviruses remain unclassified, including the chicken calicivirus.
All viruses in this family possess a nonsegmented, polyadenylated, positive-sense, single-strand RNA genome around 7.5–8.5 kilobases in length, enclosed in an icosahedral capsid of 27–40 nanometers in diameter.[citation needed]
Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment to host receptors, which mediate endocytosis. Replication follows the positive-stranded RNA virus replication model. Positive-stranded RNA virus transcription is the method of transcription. Translation takes place by leaky scanning, and RNA termination-reinitiatio...
Calicivirus infections commonly cause moderate to severe gastroenteritis, which is the inflammation of the stomach and intestines (e.g. the Norwalk virus). Symptoms can include vomiting and diarrhea. These symptoms emerge after an incubation time of 2 days and the symptoms only generally last for 3 days. Most calicivirus infections do not require m...
Establishing the viral etiology took many decades due to the difficulty of growing the virus in cell culture. In the 1940s and 1950s in the United States and Japan, caliciviridae could not be grown in culture, but as an experiment bacterial free filtrate of diarrhea was given to volunteers to check if viruses were present in volunteers' stool. Thes...
Feline calicivirus (FCV)—a member of the Vesivirus—represents an important pathogen of cats.[citation needed] Sapovirus, Norovirus, and Vesivirus have been detected in pigs, making this animal species of particular interest in the study of calicivirus pathogenesis and host range.[citation needed] The first mouse norovirus, murine norovirus 1 (MNV-1...
Australia and New Zealand, in an effort to control their rabbit populations, have intentionally spread rabbit calicivirus.
ICTV Report: CaliciviridaeCaliciviridae description page from the International Committee on Taxonomy of VirusessiteRosavirus. Rosavirus is a genus of viruses in the order Picornavirales, in the family Picornaviridae. Human and rodents serve as natural hosts. There are three species in this genus. [1] [2]
Source: Wikipedia. Pisoniviricetes is a class of positive-strand RNA viruses which infect eukaryotes. A characteristic of the group is a conserved 3C or 3C-like protease from the PA clan of proteases for processing the translated polyprotein.
