Heterogeneity in the capsid protein of bovine enteric caliciviruses belonging to a new genus.

Some bovine enteric caliciviruses form a new genus in the family Caliciviridae. In this study, Bayesian phylogenetic analysis of 31 full length capsid sequences from Europe, North America and Asia revealed that this new genus had four currently circulating lineages that showed both temporal and geographical distribution. These groupings were supported by the distribution of the frequency of pair-wise distances.
