Figure 2. Phylogenetic tree based on partial virion protein 1 (VP1) sequences (2602–2977) detected in enterovirus (EV) isolates and clinical specimens from encephalitis patients. GenBank accession nos. indicate the nucleotide sequences of EV strains of the present study. Scale bar indicates nucleotide substitutions per site. EV, enterovirus; CV-A, coxsackie virus A; CV-B, coxsackie virus B; HEV, human enterovirus; NIV, National Institute of Virology, Pune, India.
