Morphology of bluetongue virus
Virology, 1969Abstract 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.

SUMMARY Bluetongue (bt) viremia in Saanen goats was assayed by inoculating blood into embryonating chicken eggs. High-titer viremia consistently occurred in Saanen goats inoculated with either BT 8 or 63-66B strain of bt virus. Low-titer viremia consistently occurred in Saanen goats inoculated with 4 other strains of bt virus.

Nontransmission of bluetongue virus by embryos from bluetongue virus-infected sheep
American Journal of Veterinary Research, 1988SUMMARY Donor sheep were infected either by bites of bluetongue virus (btv)-infected (serotype 11, “Texas Station strain”) Culicoides variipennis or by inoculation with 100,000 median chicken embryo intravascular lethal doses of btv (serotype 11) from a suspension made from infected C variipennis.

Bluetongue (BLU) is a noncontagious viral disease. The virus is a member of the Orbivirus genus and serves as the prototype virus of the genus. BLU is primarily a disease of domestic ruminants, some wild ruminants, and, recently, domestic dogs. The disease is caused by 1 of 24 different serotypes of virus that are distributed worldwide.

Bluetongue Virus Structural Components
1990The structural components of bluetongue virus (BTV), the prototype of the orbivirus genus, has been the subject of a number of reviews (Verwoerd et al. 1979; Gorman and Taylor 1985; Spence et al. 1984). The main features can be summarized as follows: BTV is an icosahedral-shaped particle consisting of a segmented double-stranded RNA genome encapsidated

Bluetongue Virus in Pronghorn Antelope
American Journal of Veterinary Research, 1972SUMMARY Four adult pronghorn antelope (Antilocapra americana) were inoculated subcutaneously with bluetongue virus (btv) strain BT-8. Two antelope which did not possess preinoculation btv neutralizing antibodies developed clinical signs of bluetongue (bt) and died 7 and 8 days after inoculation. A low-level viremia persisted in each antelope for 3 days

Bluetongue Virus in Exotic Ruminants
Journal of the American Veterinary Medical Association, 1973SUMMARY An epizootic of a hemorrhagic disease occurred in 6 species of exotic ruminants at the San Diego Zoo and San Diego Wild Animal Park in 1970 and 1971. The disease was reproduced in deer by inoculation of pericardial and pleural fluids from a muntjac (Muntiacus reeuesi) and the spleen of a kudu (Tragelaphus capensis). The agent was also recovered

The Typing of Bluetongue Virus
Research in Veterinary Science, 1971SUMMARY Typing of bluetongue virus has been carried out by applying the technique of plaque inhibition. This method has advantages over serum virus neutralization tests in eggs, tubes or petri dishes.

The Replication of Bluetongue Virus
1990Bluetongue 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

The Evolutionary Dynamics of Bluetongue Virus
Journal of Molecular Evolution, 2010Bluetongue virus (BTV) is a midge-borne member of the genus Orbivirus that causes an eponymous debilitating livestock disease of great agricultural impact and which has expanded into Europe in recent decades. Reassortment among the ten segments comprising the double-stranded (ds) RNA genome of BTV has played an important role in generating the epidemic
