Bird flu and Marek’s disease vaccine developed by Pirbright scientists

Scientists at The Pirbright Institute have used genetic engineering to develop a vaccine that protects birds against both Marek’s disease and avian influenza, also known as bird flu. The process is faster and more efficient compared to previous methods, which will allow…

Comparative pathogenicity and transmissibility of pandemic H1N1, avian H5N1, and human H7N9 influenza viruses in tree shrews

Influenza A viruses (IAVs) continuously challenge the poultry industry and human health. Studies of IAVs are still hampered by the availability of suitable animal models. Chinese tree shrews ( Tupaia belangeri chinensis) are closely related to primates physiologically and…

Development of a RACE-based RNA-Seq approach to characterize the T-cell receptor repertoire of porcine gammadelta T cells

Recent data suggest that porcine gammadelta T cells exhibit a similar degree of functional plasticity as human and murine gammadelta T cells. Due to the high frequency of TCR-gammadelta + cells in blood and secondary lymphatic organs, the pig is an attractive model to study…

Binomial nomenclature for virus species: a consultation

The Executive Committee of the International Committee on Taxonomy of Viruses (ICTV) recognizes the need for a standardized nomenclature for virus species. This article sets out the case for establishing a binomial nomenclature and presents the advantages and disadvantages…

Identification and characterisation of a Masculinizer homolog in the diamondback moth Plutella xylostella

Recently, a novel sex-determination system was identified in the silkworm ( Bombyx mori) in which a piRNA encoded on the female-specific W chromosome silences a Z-linked gene ( Masculinizer) which would otherwise initiate male sex-determination and dosage compensation…

Nomenclature report for killer-cell immunoglobulin-like receptors (KIR) in macaque species: new genes/alleles, renaming recombinant entities and IPD-NHKIR updates

The Killer-cell Immunoglobulin-like Receptors (KIR) are encoded by a diverse group of genes, which are characterized by allelic polymorphism, gene duplications, and recombinations, which may generate recombinant entities. The number of reported macaque KIR sequences is…

Post-vaccination herd immunity against peste des petits ruminants and inter-vaccination population turnover in small ruminant flocks in northwest Ethiopia

Vaccination is the main tool for control of peste des petits ruminants (PPR) because of the availability of effective and safe vaccines that provide long lasting protection. However vaccination campaigns may not always provide sufficient herd immunity needed to prevent…

Differential expression of immune-related genes in the bursa of Fabricius of two inbred chicken lines following infection with very virulent infectious bursal disease virus

Among different inbred chickens' lines, we previously showed that lines P and N of Institute for Animal Health, Compton, UK are the most susceptible and the least affected lines, respectively, following infection with very virulent infectious bursal disease virus (vvIBDV)…

Pirbright study uncovers replication sites of emerging pig disease

A recent study carried out at The Pirbright Institute has uncovered the sites within the cell where porcine deltacoronavirus (PDCoV) makes new copies of itself during replication. Using electron microscopy, Pirbright scientists demonstrated that the virus creates replication…
