Conventional control strategies for mosquito-borne pathogens such as malaria and dengue are now being complemented by the development of transgenic mosquito strains reprogrammed to generate beneficial phenotypes such as conditional sterility or pathogen resistance. The…

In recent years, real-time reverse transcription polymerase chain reaction (rRT-PCR) has become one of the most widely used methods for the diagnosis of infectious pathogens. The combined properties of high sensitivity, specificity, and speed, along with a low contamination…

The International Committee for Taxonomy of Viruses (ICTV) recognizes four species of tick-borne orbiviruses (TBOs): Chenuda virus, Chobar Gorge virus, Wad Medani virus and Great Island virus (genus Orbivirus, family Reoviridae). Nucleotide (nt) and amino acid (aa) sequence…

Anaplasma centrale has been used in cattle as a live blood vaccine against the more pathogenic Anaplasma marginale for over 100 years. While A. marginale can be propagated in vitro in tick cell lines, facilitating studies on antigen production, immunisation and vector…

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…
