Classification of the Caliciviridae. Phylogenetic analysis of strains belonging to the so far defined genera (Norovirus, Sapovirus, Lagovirus and Vesivirus) and the two tentative genera Beco/Nabovirus and Recovirus, as indicated. The complete capsid sequence of the strains was aligned with Clustal X (Gibson et al., 1999) and a phylogenetic analysis performed with the neighbour-joining method using PAUP (Swofford, 2002). A bootstrap analysis with 1000 replicates was performed. The bootstrap values are indicated. The strains belonging to non-defined genogroups (GVI. VII, VIII and IX of sapovirus) are indicated by a question mark. The strains FCV/Dresden/2006/GE strain (Vesivirus, GenBank accession No. DQ424892), and RHDV/Dresden/2006/GE (Lagovirus, GenBank accession no. EF363035) generated within the consortium VIZIER are highlighted in bold. The tentative Genera Recovirus and Beco/Nabovirus are indicated.
