Phylogenetic analysis of the capripoxvirus RPO30 gene and its use in a PCR test for differentiating sheep poxvirus from goat poxvirus

The Genus Capripoxvirus (CaPV) of the Poxviridae family comprises sheep poxvirus (SPPV), goat poxvirus (GTPV) and lumpy skin disease virus (LSDV) which are responsible for economically important diseases affecting sheep, goats and cattle respectively. To date, there have…

Salicylidene acylhydrazide-mediated inhibition of type III secretion system-1 in Salmonella enterica serovar Typhimurium is associated with iron restriction and can be reversed by free iron

Salmonella enterica serovar Typhimurium is an animal and zoonotic pathogen of worldwide importance. Intestinal colonization, induction of enteritis and systemic translocation by this bacterium requires type III protein secretion. Strategies that target this process have the…

Influence of season and meteorological parameters on flight activity of Culicoides biting midges

Culicoides biting midges are vectors of internationally important arboviruses including bluetongue virus (BTV). The ecological constraints imposed by the small body size of these insects strongly influence the epidemiology of the diseases they can carry. Bluetongue virus…

Reanalysis of the start of the UK 1967 to 1968 foot-and-mouth disease epidemic to calculate airborne transmission probabilities

The aims of this study were to statistically reassess the likelihood that windborne spread of foot-and-mouth disease (FMD) virus (FMDV) occurred at the start of the UK 1967 to 1968 FMD epidemic at Oswestry, Shropshire, and to derive dose-response probability of infection…

Selective cloning, characterization, and production of the Culicoides nubeculosus salivary gland allergen repertoire associated with equine insect bite hypersensitivity

Salivary gland proteins of Culicoides spp. have been suggested to be among the main allergens inducing IgE-mediated insect bite hypersensitivity (IBH), an allergic dermatitis of the horse. The aim of our study was to identify, produce and characterize IgE-binding salivary…

Modelling foot-and-mouth disease virus dynamics in oral epithelium to help identify the determinants of lysis

Foot-and-mouth disease virus (FMDV) causes an economically important disease of cloven-hoofed livestock; of interest here is the difference in lytic behaviour that is observed in bovine epithelium. On the skin around the feet and tongue, the virus rapidly replicates, killing…

Receptor binding profiles of avian influenza virus hemagglutinin subtypes on human cells as a predictor of pandemic potential

The host adaptation of influenza virus is partly dependent on the sialic acid (SA) isoform bound by the viral hemagglutinin (HA). Avian influenza viruses preferentially bind the alpha-2,3 SA and human influenza viruses the alpha-2,6 isoform. Each isoform is predominantly…

RNA integrity in post mortem human variant CreutzfeldtJakob disease (vCJD) and control brain tissue

Aims: To determine premortem and post mortem factors affecting quality and yield of RNA isolated from the unique archived brain material in the UK National Creutzfeldt-Jakob Disease Surveillance Unit Brain and Tissue Bank and to compare this to control brain tissue with no…
