Caliciviruses

  • Frederick L. Schaffer
Part of the Comprehensive Virology book series (CV, volume 14)

Abstract

The name “calicivirus” is derived from the cup-shaped (chalice or kalyx) indentations observed on the surface of virions negatively stained with phosphotungstate. The caliciviruses, whose recognized members include vesicular exanthema of swine virus, feline calicivirus (formerly feline Picornavirus), and San Miguel sea lion virus, were provisionally classified as a genus of the family Picornaviridae (Melnick et al., 1974; Fenner, 1976). Based on the difference in morphology and the observa tion that caliciviruses contain only one major polypeptide, Burroughs and Brown (1974) suggested that they constitute a separate family, Caliciviridae. Although this suggestion met with some opposition (Cooper, 1974), newer information indicates that the genome strategy of caliciviruses differs significantly from that of typical picornaviruses. Consequently, the Picornavirus Study Group of the ICTV has recently recommended that the caliciviruses be excluded from the Picornaviridae and that a new study group be formed to consider them as a separate family (Cooper et al., 1978).
