Neighbor-joining trees of the nucleotide sequences of the complete ORF2 region (∼1.6 kb) (A) and the 5′-capsid N/S region (228 bases) (B and C) of NoV GII/4. Bootstrap values with 100/100 are indicated at the nodes of the tree. Sequence names are shown in the distinct color boxes on the basis of sampling sites and periods. Yellow boxes, 2006-2007 sequences obtained in the present study; green boxes, 2006/2007 sequences obtained in Europe, China, and Japan in other studies; orange boxes, <2006 sequences in Japan; pink boxes, 2005-2006 sequences in Japan: blue boxes, sequences from the global GII/4 epidemics pre-1996, 1995-1996, 2002-2003, and 2004-2005. Red letters with asterisks indicate sequences of the GII/4 2006a and 2006b epidemic strains in winter 2006-2007 in Europe (46).
