Abstract excerpt
Recent studies revealed that hepatitis E virus (HEV) genomes are more variable than previously thought and well-conserved regions suitable for designing universal primers are limited. In this study, based on alignment of 70 full-length HEV sequences of genotypes 1-4, a part of the ORF2/ORF3 overlapping region was found to be the best target region for PCR amplification of various HEV strains. Using the newly...
