Between-group average phylogenetic distances were calculated based on nucleic acid sequence alignments of the corresponding partial RdRp region of recoviruses (268 bp) and noroviruses (274 bp). Group assignments of recovirus isolates were based on those shown in Fig. 1. Norovirus genogroups were represented by the Norwalk (G1.1), Southampton (GI.2), Desert Shield (GI.3), Hawaii (GII.1), Melksham (GII.2), and Mexico (GII.3) viruses. Numbers in bold are discussed in the text.
