Susceptibility of Culicoides biting midge larvae to the insect-pathogenic fungus, Metarhizium anisopliae: Prospects for bluetongue vector control

Culicoides biting midges (Diptera: Ceratopogonidae) are responsible for the spread of several arboviruses of livestock and humans that are of international importance. This study assesses the virulence of 18 insect-pathogenic fungal strains from the genera Metarhizium…

The evolution of two homologues of the core protein VP6 of epizootic haemorrhagic disease virus (EHDV), which correspond to the geographical origin of the virus

Epizootic haemorrhagic disease virus is a 10-segmented, double-stranded RNA virus. When these ten segments of dsRNA are run on 1% agarose, eastern (Australia, Japan) and western (North America, Africa, Middle-East) strains of the virus can be separated phenotypically based…

Feline calicivirus p32, p39 and p30 proteins localize to the endoplasmic reticulum to initiate replication complex formation

In common with other positive-strand RNA viruses, replication of feline calicivirus (FCV) results in rearrangement of intracellular membranes and production of numerous membrane-bound vesicular structures on which viral genome replication is thought to occur. In this study…

Global distribution of peste des petits ruminants virus and prospects for improved diagnosis and control

Viral diseases of farm animals, rather than being a diminishing problem across the world, are now appearing with regularity in areas where they have never been seen before. Across the developing world, viral pathogens such as peste des petits ruminants virus (PPRV) place a…

Toward a global foot and mouth disease vaccine bank network

A network of foot and mouth (FMD) vaccine banks has been initiated with the support of vaccine bank managers and technical advisors that participated in a workshop held at the Institute for Animal Health, Pirbright, in the United Kingdom in April 2006. Terms of Reference…

Semliki Forest virus-induced endoplasmic reticulum stress accelerates apoptotic death of mammalian cells

The alphavirus Semliki Forest virus (SFV) and its derived vectors induce apoptosis in mammalian cells. Here, we show that apoptosis is associated with the loss of mitochondrial membrane potential followed by the activation of caspase-3, caspase-8, and caspase-9. Cell death…

Can cattle and sheep primed with one inactivated bluetongue virus serotype 8 (BTV-8) vaccine be boostered with another?

Groups of cattle and sheep that had received a primary course of vaccination with an inactivated bluetongue virus serotype 8 (BTV-8) vaccine were booster vaccinated 6 or 12 months later with the homologous vaccine or an alternative inactivated BTV-8 vaccine. The neutralising…

Evaluation of housing as a means to protect cattle from Culicoides biting midges, the vectors of bluetongue virus

The housing of animals at night was investigated as a possible means of protecting them from attack by Culicoides biting midges (Diptera: Ceratopogonidae), the vectors of bluetongue. Light-trap catches of Culicoides were compared inside and outside animal housing, in the…

A description of two outbreaks of capripoxvirus disease in Mongolia

Mongolia had no reported cases of capripoxvirus disease from 1977 until an outbreak of sheeppox in 2006/2007 and then goatpox in 2008. The two outbreaks occurred in geographically distant areas of Mongolia and, most strikingly, were highly species-specific. The 2006/2007…
