In horses, equine influenza virus (EIV) is a leading cause of respiratory disease. Conventional inactivated vaccines induce a short-lived immune response. By comparison, natural infection confers a long-term immunity to re-infection. An aim of new equine influenza vaccines is to more closely mimic natural infection in order to achieve a better quality of(More)
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)
The sequence of BamHI-I fragment of the herpesvirus of turkeys (HVT) FC126 strain DNA was analyzed for the presence of potential open reading frames (ORFs). Four complete (ORFs 2 to 5) and 2 partial ORFs (ORFs 1 and 6) were detected. ORFs 2 and 3 were homologous to the HSV-1 UL55 and the EHV-1 gene 3, respectively. The ORF 6 was already partially sequenced(More)
Dendritic cells (DCs) are bone marrow-derived antigen-presenting cells that have an exquisite capacity to interact with T cells and modulate their responses. Little is known about porcine DCs despite the fact that they represent an important target in strategies that are aimed at modulating resistance to infection in pigs and may be of major importance in(More)
A highly attenuated vaccinia virus strain, NYVAC (vP866), was derived from a plaque-cloned isolate of the Copenhagen vaccine strain by the precise deletion of 18 open reading frames (ORFs) from the viral genome. Among the ORFs deleted from NYVAC (vP866) are two genes involved in nucleotide metabolism, the thymidine kinase (ORF J2R) and the large subunit of(More)
The DNA sequence of bovine herpesvirus type 1 (BHV-1) ST strain (BHV-1.2 subtype) entire unique short (US) region and part of adjacent flanking sequences of the inverted repeats was determined. The BHV-1 ST US region is 9745 bp in size and has a 70.5% G + C content. Eight potential open reading frames (ORFs) longer than 100 amino acids and designated ORF1(More)
This study was conducted to investigate whether the co-delivery of DNA encoding porcine cytokines would enhance a protective immune response in pigs to a Pseudorabies virus (PRV; or Aujeszky's disease virus) DNA vaccine. Aujeszky's disease in pigs results in respiratory and nervous symptoms with important economic losses. To evaluate cytokine effects,(More)
The DNA sequence of the whole of the short unique region (U(s)) and that of part of the short terminal repeat (TRs) of herpesvirus of turkeys (HVT) were determined. HVT U(s) is 8.6 kbp long and contains eight potential open reading frames (ORFs). Seven of these have counterparts in the U(s) of herpes simplex virus type 1 (HSV-1). The homologous proteins(More)
Equine herpesvirus 1 (EHV-1) causes respiratory and neurological disease and abortion in horses. Animals with high frequencies of cytotoxic T lymphocytes (CTL) show reduced severity of respiratory disease and frequency of abortion, probably by CTL-mediated control of cell-associated viraemia. This study aimed to identify CTL epitopes restricted by selected(More)
Equine herpesvirus-1 (EHV-1) is a ubiquitous pathogen of horses, which continues to cause respiratory and neurological disease and abortion, despite the widespread use of vaccines. Cell mediated immunity (CMI) is thought to play a major role in protection against infection with EHV-1. The aim of this study was to characterise the virus-specific CMI response(More)
