Pathogenesis and Cross-species Infection of Hepatitis E Virus
Hepatitis E Virus (HEV), the causative agent of hepatitis E, is a zoonotic pathogen of worldwide significance. The genus Orthohepevirus A of the family Hepeviridae includes all mammalian strains of HEV and consists of 8 recognized genotypes. Genotypes 1 and 2 HEVs only infect humans and genotypes 3 …

Cross-Species Infection and Characterization of Avian Hepatitis E Virus
… identities with those isolates which cause hepatitis-splenomegaly (HS) syndrome based on partial helicase and capsid gene regions. Recovery of identical viruses from the experimentally inoculated chickens in the subsequent transmission study further confirmed our field results. The capsid …

Cross-protection and Potential Animal Reservoir of the Hepatitis E Virus
… swine HEV became infected as evidenced by fecal virus shedding and viremia, and the majority of pigs also developed IgG anti-HEV prior to challenge at 12 weeks post-inoculation. After challenge, viremia and fecal virus shedding of challenge viruses were not detected, suggesting that prior …

Foodborne Transmission and Molecular Mechanism of Cross-species Infection of Hepatitis E Virus (HEV)
Hepatitis E virus (HEV), the causative agent of hepatitis E, is an emerging virus of global distribution. At least four distinct genotypes of HEV exist worldwide: genotype 1 and 2 HEV strains are responsible for waterborne epidemics; genotype 3 and 4 HEV strains are responsible for sporadic …

Molecular and Serological Epidemiology of Swine Hepatitis E Virus from Pigs in Two Countries
Hepatitis E virus (HEV), the causative agent of hepatitis E, is endemic in many developing countries. However, sporadic cases of acute hepatitis E have also been reported in industrialized countries including the United States. Increasing evidence suggested that hepatitis E is zoonotic. Swine HEV …

Molecular Characterization of Animal Strains of Hepatitis E Virus (HEV): Avian HEV and Swine HEV
Hepatitis E virus (HEV), the causative agent of hepatitis E, is an important public health concern in many developing countries. It mainly infects young adults and has a mortality of up to 25% in pregnant women. Although hepatitis E is only sporadic in industrialized countries including the United …

Evidence of Extrahepatic Sites of Replication of the Hepatitis E Virus in a Swine Model
Hepatitis E virus (HEV) is the major cause of enterically transmitted non-A, non-B hepatitis in many developing countries, and is also endemic in many industrialized countries. Due to the lack of an effective cell culture system and a practical animal model, the mechanisms of HEV pathogenesis and …

Bestimmung der Prävalenz von Antikörpern gegen Hepatitis E Virus in Seren von Blutspendern, Schlachthauspersonal, Schweinezüchtern und Schlachtschweinen
… Bestimmung der Prävalenz von Antikörpern gegen Hepatitis E Virus in Seren von Blutspendern, Schlachthauspersonal, Schweinezüchtern und Schlachtschweine. Es wurden Blutproben von Schlachthauspersonal, Schweinezüchtern und Schlachtschweine, aus vier verschiedenen Provinzen in Nordgriechenland …

Mechanism of Pathogenesis and Replication of an Avian Strain of the Hepatitis E Virus in a Chicken Model
Hepatitis E is an acute, enterically transmitted disease of public health importance. The mechanism of pathogenesis of HEV is poorly understood due to the lack of an in vitro cell culture system and an ideal animal model system. With the discovery of avian HEV and its association with a hepatic …

Knowledge, attitudes and practices regarding the risk of Hepatitis E virus among the residents of Havana information settlement in Windhoek, Namibia
… every year there are an estimated 20 million Hepatitis E virus infections worldwide, leading to an estimated 3.3 million symptomatic cases of hepatitis E. The 237 probable and confirmed cases at health facilities in Windhoek district are mostly from Havana informal settlement. These areas are …

Understanding the Role of the Hypervariable Region in the Open Reading Frame 1 of the Hepatitis E virus in Viral Replication
Hepatitis E virus (HEV) is a major cause of enterically transmitted acute viral hepatitis in developing countries that lack proper hygienic infrastructure. Hepatitis E is globally distributed and has emerged as an important public health disease in both developing and industrialized countries. HEV …

Characterization of an Amphipathic Alpha-Helix in the Membrane Targeting and Viral Genome Replication of Brome Mosaic Virus
Positive-strand RNA viruses associate with specific organelle membranes of host cells to establish viral replication complexes. The replication protein 1a of brome mosaic virus associates strongly with the nuclear endoplasmic reticulum (ER) membranes, invaginates membranes into the lumen, and …

Discovery of Novel Strains of Animal Hepatitis E Viruses in the United States: Antigenic and Genetic Characterization, Cross-Species Infection, and Public Health Implications
Hepatitis E virus (HEV) is an important human pathogen, with pigs and likely other animal species serving as natural reservoirs. There are currently four recognized HEV genotypes that infect humans within the genus Hepevirus of the family Hepeviridae. Genotypes 1 and 2 are human viruses that are …
