The Replication of Bluetongue Virus

1990
Bluetongue virus (BTV) replicates in the cytoplasm of a wide variety of cell types and infection ultimately leads to cell death. The studies of Verwoerd, Huismans and others in the late 1960s and continuing to the present (see Chap. 2, this volume) on the double-stranded, segmented genomic RNA (Verwoerd 1969; Verwoerd et al. 1970), the bishelled nature

Morphology of bluetongue virus

Virology, 1969
Abstract Electron micrographs of highly purified bluetongue virus, negatively stained with phosphotungstate, are presented. The morphological details suggest that the capsid of the virion consists of a single layer of 32 capsomeres arranged in 5:3:2 symmetry. The size of the virion is about 54 mμ, and it has no envelope.

The Pathology and Pathogenesis of Bluetongue

Journal of Comparative Pathology, 2009
Bluetongue (BT) is an insect-transmitted viral disease of wild and domestic ruminants and, occasionally, other species. Amongst domestic livestock, BT is most common in certain breeds of sheep whereas asymptomatic BT virus (BTV) infection of cattle is typical in enzootic regions.

Coordinating the approach to bluetongue

Veterinary Record, 2008
SIR, — I would like to congratulate the British Cattle Veterinary Association (bcva) on organising a superb day meeting on bluetongue virus (btv) last week. An impressive multinational and multi-disciplinary panel of speakers explained the potential of the impact of btv on the uk ...

BLUETONGUE: THE DISEASE IN CATTLE

Australian Veterinary Journal, 1975
Most researchers in South Africa found that although BT virus could be isolated from apparently healthy cattle and from inoculated cattle the virus did not produce overt clinical disease in cattle. However, when epizootics were reported outside Africa, clinical signs were observed in cattle in Israel, Palestine, Syria, Portugal, and Spain. Most natural

Bluetongue

Bluetongue (BT) disease, caused by bluetongue virus (BTV) is an acute hemorrhagic fever of domesticated and wild ruminants. An inactivated pentavalent vaccine consisting of BTV serotypes 1, 2, 10, 16, 23 is currently being used in some parts of India.

Bluetongue: Laboratory diagnosis

Comparative Immunology, Microbiology and Infectious Diseases, 1994
Definitive diagnosis of bluetongue virus (BTV) infection, often subclinical in domestic and wild ruminant relies heavily on laboratory techniques for BTV isolation and demonstration of BTV antigens, viral nucleic acids and antibodies. The virus can be isolated from blood components, mainly the erythrocyte fraction, collected from affected animals ...

Vaccination against bluetongue

Veterinary Record, 2008
SIR, — The recent re-emergence of blue-tongue in Europe is a timely reminder of the need to vaccinate and remain vigilant for signs of the disease. New instances of bluetongue virus serotype 8 (btv-8) were first reported in France in July.

Bluetongue vaccination in England

Veterinary Record, 2008
SIR, — The uk, and England in particular, is under considerable threat from an epidemic of bluetongue. However, a vaccine is now available. Take up needs to be high. Through the veterinary profession encouraging its clients to use the vaccine, this threat may well be averted.

Bluetongue and midge control

Veterinary Record, 2007
Simon Carpenter, Philip Mellor and Steve Torr comment: Dr Wade raises the important issue of midge control via insecticide application to livestock as a potential means of interrupting transmission of bluetongue virus (btv).
