Coccidiosis is an economically important disease in chickens, caused by infection with Eimeria species parasites. Diagnosis of coccidiosis is frequently based on oocyst enumeration in pooled faecal samples or litter. In studies on infection dynamics and for monitoring in the…

The spread of bluetongue virus (BTV) is most successfully controlled by vaccination of susceptible ruminant populations. Currently two different types of BTV vaccines are used for this purpose; inactivated, mostly monovalent vaccine formulations and modified live virus…

Interferon-gamma (IFN-gamma) and interleukin (IL)-10 are cross-regulatory cytokines capable of driving and controlling the adaptive host immune response. The inter-relationship between IFN-gamma and IL-10 expression has not been defined in sheep despite biological evidence…

Background: The chemokine and chemokine receptor families play critical roles in both the healthy and diseased organism mediating the migration of cells. The chemokine system is complex in that multiple chemokines can bind to one chemokine receptor and vice versa. Although…

Conformational transitions in the prion protein (PrP) are thought to be central to the pathogenesis of the transmissible spongiform encephalopathies (TSE), such as Creutzfeldt-Jacob disease and bovine spongiform encephalopathy. Studies of prion phenomena in yeast have shown…

Developmental lesions of the central nervous system (CNS) have been described associated with transplacental infection with bluetongue virus (BTV) in cattle (MacLachlan and others 1985) and sheep (Osburn 1972). In the past, the development of these deformations was mostly…

A quarantine period for potentially contaminated personnel can be used to reduce the risk of transfer of foot-and-mouth disease virus (FMDV) from infected to susceptible premises. This is set at 72 hours in the UK, on the basis of results from laboratory studies and field…

A cDNA encoding the chicken orthologue of dendritic cell-lysosomal associated membrane protein (DC-LAMP)/CD208 was cloned by RT-PCR from RNA isolated, from mature chicken bone marrow-derived dendritic cells (chBM-DCs). The cloned chicken DC-LAMP (chDC-LAMP) cDNA consists of…

Dendritic cells (DCs) are bone marrow-derived professional antigen-presenting cells. The in vitro generation of DCs from either bone marrow or blood is routine in mammals. Their distinct morphology and phenotype and their unique ability to stimulate naïve T cells are used to…
