Citation: N/A Interpretive Summary: The caliciviruses are a family of viruses that is just recently beginning to be understood sufficiently to classify them into distinct subgroups or genera. The Calicivirus Study Group of the International Committee on Taxonomy of Viruses has recently submitted recommendations for classification of these viruses into distinct groups based on structure, genetic information and similarity of the viral proteins. The feline, San Miguel sea lion virus and vesicular exanthema of swine caliciviruses were placed into the Vesivirus group. The rabbit hemorrhagic disease virus and European brown hare syndrome virus were placed into the Lagovirus group. Norwalk-like human caliciviruses were placed into the Norwalk group and the Sapporo-like human caliciviruses were placed into the Sapporo group. Hepatitis E was removed from the Calicivirus family for lack of evidence that it should be classified here. The is the first accurate classification of these viruses based on host range, disease caused and genetic relatedness.
Technical Abstract: The International Committee on Taxonomy of Viruses (ICTV) has recently approved several proposals submitted by the present Caliciviridae Study Group. These proposals include the division of the family into 4 new genera designated Lagovirus, Vesivirus, "Norwalk-like viruses (NLVs)", and "Sapporo-like viruses (SLVs)"; the latter 2 genera were assigned temporary names until acceptable names can be determined by the scientific community. The genera have been further divided into the following species: Feline calicivirus and Vesicular exanthema of swine virus (genus Vesivirus), Rabbit hemorrhagic disease virus and European brown hare syndrome virus (genus Lagovirus), Norwalk virus (genus NLV), and Sapporo virus (genus SLV). In addition, the ICTV approved a proposal to remove the hepatitis E virus from the Caliciviridae into an "unassigned" classification status.
