Figure 2. . Genetic relationships of partial viral protein 7 (A) and viral protein 4 (B) nucleotide sequences for novel rotavirus strain (black dot) isolated from 36-month-old child with diarrhea compared with representatives of known equine, simian, and human rotavirus genotypes. Evolutionary relationships and distances were inferred by using the maximum-likelihood method in PhyML 3.0 (13). Numbers next to nodes are approximate likelihood-ratio test values calculated by PhyML. Rotavirus strain designations, and G and P genotypes are shown. Scale bars indicate number of nucleotide substitutions per site.
