Phylogenetic tree for a 347-nt sequence within open reading frame 2 of hepatitis E viruses, France. Genetic distances were calculated by using the Kimura 2-parameter method, and the tree was plotted using the by the neighbor-joining method. Values along branches are bootstrap values acquired after 100 replications. Virus sequences obtained from patients in this study (gray shading) were compared with reference sequences of subtypes 3 viruses according to the proposal of Smith et al. (3). GenBank accession numbers, genotypes, and countries of origin are listed. Reference sequence in bold is from a hepatitis E virus genotype 3-ra isolated from a human. Scale bar indicates nucleotide substitutions per site.
