Detection of hepatitis E virus on a blood donor and its infectivity to rhesus monkey / 中华肝脏病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To understand the infectivity and pathogenicity of the plasma of hepatitis E virus (HEV) viremia to primate animals.</p><p><b>METHODS</b>RNA fragment of HEV genotype IV was detected on one healthy donor who was positive for anti-HEV IgM and negative for anti-HEV IgG. Then 10 ml plasma from above donor was transfused to rhesus monkey to observe its infectivity and pathogenicity.</p><p><b>RESULTS</b>Acute hepatitis E was developed in rhesus monkey who accept HEV RNA positive plasma. It was confirmed by virological, immunological, biochemical and histopathological data.</p><p><b>CONCLUSION</b>Acute hepatitis E can be induced by plasma transfusion of HEV viremia, which indicate the possibility of transfusion transmitted hepatitis E</p>
