Phylogenetic analysis illustrating genetic relationships between HRV species based on sequence alignment of 6 complete coding sequences amplified from our study (black triangle) compared with all known HRV prototypes. The neighbor-joining phylogenetic tree was constructed using Kimura's two-parameter with 1,000 bootstrap replicates using the MEGA4 program. Evolutionary distance was represented by the scale bar in the unit of nucleotide substitutions per site. The selected HRV strain name in this study refers to number of specimen and patient's admission month and year.
