Hepatitis E virus (HEV) is a significant health problem in developing countries causing sporadic and epidemic forms of acute viral hepatitis. Hepatitis E is a self-limiting disease; however, chronic HEV infections are being reported in immunocompromised individuals. The disease severity is more during pregnancy with high mortality (20-25%), especially in third trimester. Early cellular response...

BACKGROUND The prevalence of hepatitis E virus (HEV) genotype 3 infections in the English population (including blood donors) is unknown, but is probably widespread, and the virus has been detected in pooled plasma products. HEV-infected donors have been retrospectively identified through investigation of reported cases of possible transfusion-transmitted hepatitis E. The frequency of HEV trans...

UNLABELLED Hepatitis E virus (HEV) causes both the endemic and epidemic spread of acute hepatitis in many parts of the world. HEV open reading frame 3 (ORF3) encodes a 13-kDa multifunctional protein (vp13) that is essential for HEV infection of animals. The exact role of vp13 in HEV infection remains unclear. In this study, vp13 was found to enhance interferon (IFN) production induced by poly(I...

BACKGROUND In recent years various studies showed, that hepatitis E virus (HEV) is a growing public health problem in many developed countries. Therefore, HEV infections might bear a transmission risk by blood transfusions. The clinical relevance still requires further investigations. The aim of this study was to provide an overview of acute HEV infections in Upper Austrian blood donors as well...

conclusions this study provides support for the hypothesis that humans are probably infected after contact with swine sources. the findings emphasize the importance of checking the country of origin of swine and of improving sanitary control measures from the veterinary standpoint to prevent the spread of hev infection in italy. materials and methods a total of 327 hev sequences of swine and hu...

High-throughput sequencing of bile and feces from two pigs experimentally infected with human hepatitis E virus (HEV) of genotype 3f revealed the same full-length consensus sequence as in the human sample. Twenty-nine percent of polymorphic sites found in HEV from the human sample were conserved throughout the infection of the heterologous host. The interspecies transmission of HEV quasispecies...

Prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis G virus (HGV), and hepatitis E virus (HEV) was investigated among 574 healthy blood donors in Bolivia. HCV RNA and HGV RNA in the serum were identified by a nested reverse transcription-PCR using primers derived from the 5' untranslated region (5' UTR). We also tested for hepatitis B surface antigen (HBsAg) and for the an...

The aim of this study was to further investigate the role of wild boar (Sus scrofa) as a reservoir for hepatitis E virus (HEV). Sixty-four blood and faecal samples collected from wild boar hunted in Central Italy in 2011-2012 were examined by indirect enzyme-linked immunosorbent assay and RT-PCR analysis. Positive RT-PCR samples were further examined by nucleotide sequence determination and sub...

BACKGROUND The source and route of autochthonous hepatitis E virus (HEV) infections are not clearly established in industrialized countries despite evidence that it is a zoonosis in pigs. We investigated the role of figatellu, a traditional pig liver sausage widely eaten in France and commonly consumed raw, as a source of HEV infection. METHODS A case-control study was conducted of 3 patients...

Hepatitis E virus (HEV) is the most common cause of acute viral hepatitis in China. Recently, a shift in molecular epidemiology from hepatitis E genotype 1 (HEV-1) to hepatitis E genotype 4 (HEV-4) has been observed in Northern China, marking a switch from human-to-human transmission to zoonosis. However, similar data from cities in Southern China are lacking. This observational study of human ...
