Molecular phylogenetic analysis of VP1 gene from Indian (a) and global (b) isolates. The evolutionary history was inferred by using the maximum likelihood method based on the Hasegawa-Kishino-Yano model. The bootstrap consensus tree inferred from 1000 replicates is taken to represent the evolutionary history of the taxa analysed. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) is shown next to the branches. Red box—isolate from present study
