Abstract

In total, 335 serum samples were collected from rabbits from two farms in Gansu province, China, and tested for anti‐hepatitis E virus (HEV) antibody using EIA and for HEV RNA using nested RT‐ PCR with ORF2 primers. The overall prevalence of anti‐HEV antibody and HEV RNA was 57.0% (191/335) and 7.5% (25/335), respectively. The positivity rate of HEV RNA in the anti‐HEV antibody negative group (7.6% (11/144)) did not differ significantly from that in the positive group (7.3% (14/191)). The concordance between HEV RNA and anti‐HEV antibody was 43.3% with no significant correlation (P < 0.05). All 25 amplicons from the ORF2 region were cloned and sequenced. On the basis of nucleotide sequence comparison, they had 84–99% identity to each other and 73–77%, 70–76%, 75–82%, 71–77%, and 53–65% with the corresponding regions of genotypes 1, 2, 3, 4, and avian HEV, respectively. Samples that were positive with the ORF2 primers were amplified using ORF1 region primers; 17 were positive and shared 71–78%, 73–76%, 74–82%, 72–78%, and 39–58% identity with the corresponding regions of genotypes 1, 2, 3, 4, and avian HEV, respectively, at the nucleotide level. Two representative full‐length sequences were determined. These two sequences shared 85% identity with each other and had 74%, 73%, 78–79%, 74–75%, and 46–47% identity to full‐length genotypes 1, 2, 3, 4, and avian HEV, respectively. Thus, the sequences isolated from the rabbits represent a novel genotype of HEV. This study provides novel information about HEV genotypes infecting rabbits as well as evidence of a new mammalian genotype of HEV. J. Med. Virol. 81:1371–1379, 2009. © 2009 Wiley‐Liss, Inc.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
