Aedes mosquitoes include important vector species such as Aedes aegypti, the major vector of dengue. Genetic control methods are being developed for several of these species, stimulated by an urgent need owing to the poor effectiveness of current methods combined with an…

In recent years, several emerging vectorborne diseases, including bluetongue (BTV-1, BTV-4 and BTV-8), Bagaza, Schmallenberg, Usutu and West Nile, have been reported in southern Spain, most of them originating from north Africa. Although EHDV circulation has been recently…

This chapter contains sections titled: The Coronavirinae, Infectious bronchitis, Coronavirus genome organisation, The coronavirus replication cycle, Development of reverse genetics system for coronaviruses including IBV, Reverse genetics system for IBV, Reverse genetics…

To assess the effect of various vaccine strains on replication and shedding of virulent Marek's disease virus from experimentally infected chickens, quantitative PCR (q-PCR) methods were developed to accurately quantify viral DNA in infected chickens and in the environment…

The ovarian tumour (OTU) domain of the nairovirus L protein has been shown to remove ubiquitin and interferon-stimulated gene 15 protein (ISG15) from host cell proteins, which is expected to have multiple effects on cell signalling pathways. We have confirmed that the OTU…

We have created a completely helper cell-dependent morbillivirus by modifying the genome to remove the coding sequence of the phosphoprotein (P) and recovering the recombinant virus in a cell line constitutively expressing the P protein. The P protein-deleted virus (P?) grew…

Gene silencing by RNA interference (RNAi) is an important research tool in many areas of biology. To effectively harness the power of this technique in order to explore tick functional genomics and tick-microorganism interactions, optimised parameters for RNAi-mediated gene…

One of the big surprises about the devastating outbreak of bluetongue serotype-8 that spread across Northern and Western Europe between 2006 and 2008 was how relatively quickly the virus was controlled and eradicated from affected countries. This was at least in part…

The aim of this study was to assess the pathogenicity and infection kinetics of Bluetongue virus serotype 26 (BTV-26) in goats. Out of a group of six goats housed in insect free accommodation, five were experimentally infected with BTV-26 and one was kept uninfected as an in…

The species Corriparta virus (CORV), within the genus Orbivirus, family Reoviridae, currently contains six virus strains: corriparta virus MRM1 (CORV-MRM1); CS0109; V654; V370; Acado virus and Jacareacanga virus. However, lack of neutralization assays, or reference genome…
