Phylogenetic trees of partial VP7 nucleotide sequences derived from rotavirus strains detected in this study and other reference strains from the GenBank database. A, B, C, and D represent G1, G2, G3, and G9 genotypes, respectively. The trees were generated using the neighbor-joining analysis of 1000 repetitions in MEGA 5.1. The scale bar indicates nucleotide substitutions per site. Bootstrap values >70% are shown at the branch nodes. Rotavirus strains in the present study are indicated in bold.
