Back to article Figure 2. Phylogenetic relationships among human and animal NLVs clustering in genogroup (GG) I and II, based on a 145-bp nucleotide sequence within RNA polymerase gene. Dendrogram includes 14 calf herd (CH) sequences from the bovine NET/98 cluster (CH138, CH156, CH131, CH168, CH182, CH176 [Bo/NLV/176/1998/NET], CH163, CH188, CH169, CH161, CH126, CH140, CH170, and CH178 described in this study), and sequences from Norwalk virus (NV), Mexico virus (MX), Newbury agent (NA), Jena virus (JV), Sw/NLV/43/1997/JP, and the swine sequences described in this study: Sw/NLV/34/1998/NET and Sw/NLV/89/1998/NET. The SLV strain Sapporo (SAP) was included for comparison. Sequences of prototype strains of NLV were obtained from GenBank (Accession numbers: NV [M87661], MX [U22498], Newbury agent [AF097917], Jena virus [AJ011099], Sw/NLV/43/1997/JP [AB009412] and SAP [S77903]). Bootstrap values for each node are given if >50%.
