Genetic Variants of Echovirus 13, Northern India, 2010
Figure. . Phylogenetic tree based on alignments of partial viral protein 1 gene sequences of echovirus 13 (E13) constructed by the neighbor-joining method implemented in MEGA version 5.05 software (7) by using the Kimura-2 parameter nucleotide substitution model. Bootstrap analysis included 1,000 pseudoreplicate datasets. Clusters are labeled A, B, C, and D. Square indicates Uttar Pradesh E13 from fecal samples. All Uttar Pradesh E13 isolates on the tree are identified by using the same numbers listed in Table 1. Triangle indicates E13 prototype Del Carmen and the out-group enterovirus 69. Scale bar indicates nucleotide substitutions per site.
