Figure 2From: Molecular characterization and phylogenetic analysis of transmissible gastroenteritis virus HX strain isolated from China Multiple sequence alignment of S among TGEV strains. (A) A 6-nt deletion in the S gene at nt position 1123–1128 of the HX, SC-Y, and WH-1 strains. (B) Amino acid alignments of deduced S sequences compared with strain HX. (▲) indicates amino acid 585, (★) indicates amino acids of the HX, SC-Y, and WH-1 strains that are different from those of other transmissible gastroenteritis viruses.Back to article page
