This study aimed to develop a specific and sensitive reverse transcription polymerase chain reaction enzyme-linked immunosorbent assay (RT-PCR-ELISA) for detecting hepatitis E virus (HEV). Eight sets of primers and biotinylated probes designed in the ORF2-ORF3 overlapping region of HEV were tested for sensitivity. The ability of nested reverse transcription polymerase chain reaction (RT-PCR) and RT-PCR-ELISA to detect HEV was compared. RT-PCR-ELISA was 10-100 times more sensitive than nested RT-PCR and could detect 0.01 ng/μl HEV in swine stool samples. In terms of specificity, RT-PCR-ELISA did not falsely detect HEV when other viruses such as hepatitis A virus, rotavirus, norovirus genotype I, norovirus genotype II, and Feline calicivirus were present. Therefore, RT-PCR-ELISA appears to be a sensitive and specific method for detecting HEV.
