Figure 2From: Determination of the full-genome sequence of hepatitis E virus (HEV) SAAS-FX17 and use as a reference to identify putative HEV genotype 4 virulence determinants Secondary structures of the 5'-UTR region of HEV genotypes 3 (A) and genotypes 4 (B), as predicted by the mfold program. Arrows indicates the nucleotide variation between the different genotypes. Back to article page
