Asian Musk Shrew as a Reservoir of Rat Hepatitis E Virus, China
Figure. . . Phylogenetic analysis of rat hepatitis E virus (HEV) isolated from Asian musk shrews (Suncus murinus) in Zhanjiang City, China. Nucleic acid sequence alignment was performed by using ClustalX 1.81 (www.clustal.org). The genetic distance was calculated by using the Kimura 2-parameter method. The phylogenetic tree, with 1,000 bootstrap replicates, was generated by the neighbor-joining method based on the partial sequence (281 nt) of HEV open reading frame 1 of genotype 1–4, wild boar, rabbit, ferret, bat, avian, and rat HEV isolates. The scale bar indicates nucleotide substitutions per site.
