Taxonomy of the caliciviruses

The International Committee on Taxonomy of Viruses (ICTV) has recently appr oved several proposals submitted by the present Caliciviridae Study Group. These proposals include the division of the family into 4 new genera design ated Lagovirus, Vesivirus, "Norwalk-like viruses" (NLVs), and "Sapporo-like viruses" (SLVs); the latter 2 genera were assigned temporary names until a cceptable names can be determined by the scientific community. The genera h ave been further divided into the following species: Feline calicivirus and Vesicular exanthema of swine virus(genus Vesivirus), Rabbit hemorrhagic di sease virus and European brown have syndrome virus (genus Lagovirus), Norwa lk 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.
