Figure 1.   Phylogenetic tree of noroviruses based on the 330 -bp region (for GI) and 344 -bp region (for GII) of the capsid N terminus/shell gene. Fourteen novel sequences were included, designated according to isolate code, place, and year (e. g. , DR 001 -Madag 04); 25 sequences of reference norovirus strains (6) were included, designated according to genogroupgenotype, place, country, and year (e. g. , GII-2/Melksham-GRB 1994). Comparative strains are GI-1/NV-USA 1968 (Norwalk, M 87661), GI-2/SOV-GBR 1993 (Southampton, L 07418), GI-3/DSVUSA 1993 (Desert Shield, U 04469), GI-4/Chiba-JPN 2000 (AB 042808), GI-5/Musgrov-GBR 1989 (Musgrove, AJ 277614), GI-6/Hesse-DEU 1998 (AF 093797), GI-7/Wnchest-GBR 1994 (Winchester, AJ 277609), GI-8/Boxer-USA 2001 (AF 538679), GII-1/Hawai-USA 1971 (U 07611), GII-2/Melksham-GBR 1994 (X 81879), GII-3/Toronto-CAN 1993 (U 02030), GII-4/Bristol-GBR 1993 (X 76716), GII 5/Hillingd-GBR 1990 (Hillingdon, AJ 277607), GII-6/Seacrof-GBR 1990 (Seacroft, AJ 277620), GII-7/Leeds-GBR 1990 (AJ 277608), GII-8/Amstdam-NLD 1990 (Amsterdam, AF 195848), GII 9/VABeach-USA 1997 (AY 038599), GII-10/Erfurt-DEU 2000 (AF 427118), GII-11/SW 918 -JPN 1997 (AB 074893), GII-12/Wortley-GBR 1990 (AJ 277618), GII-13/Faytvil-USA 1998 (Fayetteville, AY 113106), GII-14/M 7 -USA 1999 (AY 130761), GII-15/J 23 -USA 1999 (AY 130762), GII-16/Tiffin-USA 1999 (AY 502010), and GII-17/CSE 1 -USA 2002 (AY 502009).
