Ixodes spp. ticks are known to occasionally harbour spiroplasmas – helical mycoplasmas in the class Mollicutes; a previous study in Slovakia reported an overall prevalence of Spiroplasma ixodetis of 3% in Ixodes ricinus. In the present study, extracts of unfed adult I…

Bovine respiratory syncytial virus (BRSV) is a major cause of respiratory disease in cattle worldwide. Calves are particularly affected, even with low to moderate levels of BRSV-specific maternally derived antibodies (MDA). Available BRSV vaccines have suboptimal efficacy in…

The regulatory elements which control the processes of virus replication and gene expression in the Orbivirus genus are uncharacterised both in terms of their locations within genome segments and their specific functions. The reverse genetics system for the type species…

Eradication of bluetongue virus is possible, as has been shown in several European countries. New serotypes have emerged, however, for which there are no specific commercial vaccines. This study addressed whether heterologous vaccines would help protect against 2 serotypes…

Naturally occurring cancers in non-laboratory species have great potential in helping to decipher the often complex causes of neoplasia. Wild animal models could add substantially to our understanding of carcinogenesis, particularly of genetic and environmental interactions…

Determining the host feeding patterns of mosquitoes by identifying the origin of their blood-meals is an important part of understanding the role of vector species in current and future disease transmission cycles. Collecting large numbers of blood-fed mosquitoes from the…

Background and objectives: Swine vesicular disease virus (SVDV) is a close relative of the human Enterovirus B serotype, coxsackievirus B5. As the etiological agent of a significant emergent veterinary disease, several studies have attempted to explain its origin. However…

Previous studies show that a recombinant modified vaccinia Ankara (MVA) virus expressing VP2 of AHSV serotype 4 (MVA-VP2) induced virus neutralising antibodies in horses and protected interferon alpha receptor gene knock-out mice (IFNAR ?/?) against challenge. Follow up…

The spectacular and unprecedented outbreaks of bluetongue virus (BTV) that have occurred in Europe since 1998 have led to increased interest in those factors that determine competence of Culicoides biting midges (Diptera: Ceratopogonidae) for arboviruses. In this review the…

Dengue is a major mosquito-borne disease, increasing in prevalence and severity; there are no specific drugs or licensed vaccine. It is primarily transmitted by one mosquito species, Aedes aegypti. We released transgenic ‘sterile’ male mosquitoes in Itaberaba, a suburb of…
