FIG. 2.

Alignment of genotype consensus VP1 amino acid sequences. The EV71 consensus sequence shows amino acid residues that are identical in at least 85% of all strains and those that are identical in at least 50% but less than 85% of all strains. Sites that are identical in all strains of all genotypes are double underlined; those that are identical in all strains of genotypes B and C, but different in BrCr-CA-70, are single underlined. The genotype consensus sequences indicate sites of at least 85% consensus among all strains of a given genotype (hyphens) and sites that are characteristic of one or more genotypes (uppercase letter, 85% consensus within genotype; lowercase letter, 50 to 85% consensus within genotype).
