To study numerical changes in intestinal macrophages and variations in cytokine production by immune cells in the intestine, conventional C57BL/6J mice were orally infected with the Rocky Mountain Laboratory strain of scrapie. Animals were sacrificed at different timepoints…

Epizootic haemorrhagic disease virus (EHDV) infects wild ruminants, causing a frequently fatal haemorrhagic disease. However, it can also cause bluetongue-like disease in cattle, involving significant levels of morbidity and mortality, highlighting a need for more rapid and…

In mid September 2008, clinical signs of bluetongue (particularly coronitis) were observed in cows on three different farms in eastern Netherlands (Luttenberg, Heeten, and Barchem), two of which had been vaccinated with an inactivated BTV-8 vaccine (during May-June 2008)…

T cell receptor (TCR) recognition of peptide-MHC class I (pMHC) complexes is a crucial event in the adaptive immune response to pathogens. Peptide epitopes often display a strong dominance hierarchy, resulting in focusing of the response on a limited number of the most…

Bluetongue virus (BTV), prototype species of genus Orbivirus, belongs to the family Reoviridae. It is a non-enveloped, double shelled virus with ten segmented dsRNA genome. RNA segment 6 encodes an outer capsid serotype specific virus protein VP5. A pair of primers (forward…

The innate immune response provides a critical defense against microbial infections, including viruses. These are recognised by pattern recognition receptors including Toll-like receptors (TLRs) and RIG-I like helicases (RLHs). Detection of virus triggers signalling cascades…

Although few simian rotaviruses (RVs) have been isolated, such strains have been important for basic research and vaccine development. To explore the origins of simian RVs, the complete genome sequences of strains PTRV (G8P[1]), RRV (G3P[3]), and TUCH (G3P[24]) were…

The risk of classical scrapie in sheep is associated with polymorphisms in the prion protein (PrP) gene. In recent years, large-scale selective breeding programmes for sheep at lower risk of disease have been undertaken across the European Union. We analysed large-scale…

Foot-and-mouth disease virus (FMDV) is the causative agent of a highly contagious acute vesicular disease affecting cloven-hoofed animals, including cattle, sheep and pigs. The current vaccine induces a rapid humoral response, but the duration of the protective antibody…
