FIG 8.

Sequence alignment of the lethal and nonlethal strains of CV-A6. The amino acid sequences of the P2 regions of CV-A6 strains from Changchun and other places in China and worldwide were aligned, and specific positions possibly associated with lethality are indicated, based on the differences between the lethal group (containing Changchun046, Changchun097, and Changchun099) and the nonlethal group (containing Changchun098). Dashes stand for amino acid residues identical to those of Changchun098.
