Phylogenic tree of partial noroviruses VP1 gene in human and water specimens. (a) genogroup I (b) genogroup II of partial norovirus capsid VP1 gene sequences (GI according to reference sequence KF306212 at 5339–5668; GII according to reference sequence KU561249 at 5051–5373) were aligned and phylogenetic trees were generated using the neighbor-joining method by MEGA 4.0 software. Bootstrap values of 1000 replications are shown on the branches. Green color and purple color indicate norovirus from the water and human specimens, respectively. Reference sequences from GenBank are named by genotype, accession number, country and year of detection. The GenBank accession numbers of the GII.17 sequences from patient 1~4, 6~13, 16~19 are MF996723-MF996738 and the GI strains sequences from patient 5, 10, 11, 14, 15 are MF996717- MF996722
