Two recombinant herpesviruses of turkey (HVT) expressing the VP2 protein of infectious bursal disease virus (IBDV or Gumboro disease virus) have been constructed: vHVT001 and vHVT002. The VP2 open reading frame was inserted at the locus of the small subunit of ribonucleotide reductase gene (HSV-1 UL40 homolog) without any exogenous promoter in vHVT001 and(More)
Hepatitis E virus (HEV) causes acute, enterically transmitted hepatitis in human. It is associated with large epidemics in tropical and subtropical regions where it is endemic or with sporadic cases in non-endemic regions. Unlike other hepatitis viruses, HEV has several animal reservoirs. Phylogenetic studies on HEV human and animal sequences, and the(More)
Frequent zoonotic transmission of hepatitis E virus (HEV) has been suspected, but data supporting the animal origin of autochthonous cases are still sparse. We assessed the genetic identity of HEV strains found in humans and swine during an 18-month period in France. HEV sequences identified in patients with autochthonous hepatitis E infection (n = 106)(More)
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(More)
Hepatitis E virus (HEV) is present in different species and ecological niches. It has been divided into 4 major mammalian genotypes. In this study, 3 new full-length genomes of swine HEV were sequenced and the results did not reveal any particular host determinant in comparison with human isolates belonging to the same genotype. Nucleotide composition and(More)
UNLABELLED Hepatitis E virus (HEV) causes acute enterically transmitted hepatitis. In industrialized countries, it is a zoonotic disease, with swine being the major reservoir of human HEV contamination. The occurrence and severity of the disease are variable, with clinical symptoms ranging from asymptomatic to self-limiting acute hepatitis, chronic(More)
A cDNA copy of the RNA encoding the fusion (F) protein of Newcastle disease virus (NDV) strain Texas, a velogenic strain of NDV, was obtained and the sequence was determined. The 1,792-base-pair sequence encodes a protein of 553 amino acids which has essential features previously established for the F protein of virulent NDV strains. These include the(More)
A recombinant fowlpox virus expressing the hemagglutinin-neuraminidase (HN) protein of Newcastle disease virus (NDV) strain Texas was generated. Immunoprecipitation with chicken anti-NDV serum confirmed authentic expression of the HN protein. Protection of chickens from infection with NDV was observed when birds were immunized with the recombinant HN(More)
A virus isolated from Muscovy ducks can be classified as an adenovirus on chemical and morphological grounds. It shares the avian group antigen and is not related to 12 fowl, two turkey and one duck prototype strains of adenovirus. The virus grows well in cells of duck and fowl origin, and is probably a new duck adenovirus serotype.
Newcastle disease virus (NDV) is a paramyxovirus that bears two envelope glycoproteins at the virion surface. These proteins, fusion and hemagglutinin-neuraminidase (HN), are involved in the immune response against NDV infection. Recombinant cells constitutively expressing at their surface the HN protein from the velogenic Texas strain were generated by(More)
