Border disease: Tissue culture studies of the virus in sheep

American Journal of Veterinary Research, 1982
SUMMARY A California strain of border disease (bd) virus was isolated from the cns and spleen of an infected lamb and was propagated without cytopathic effect in 2 tissue culture systems. Viral antigen was detected in the cytoplasm of infected cells by immunofluorescence.

Natural border disease virus infection in feedlot lambs

Veterinary Record, 2014
Border disease is caused by border disease virus (BDV, a pestivirus from the family Flaviviridae ) infection in sheep and goats (Vantsis and others 1976). BDV infection causes sizeable economic losses in sheep production around the world. In Spain, serological surveys have found 100 per cent flocks and 8–93 per cent sheep seropositive, respectively ...

The production and survival of lambs persistently infected with border disease virus

Comparative Immunology, Microbiology and Infectious Diseases, 1992
From 1985 to 1989 lambs persistently infected with border disease virus (BDV) were produced for comparative immunological studies by infecting 57 susceptible pregnant ewes between 50 and 60 days' gestation with Moredun or Oban strains of BDV. Ewes were infected either by injection with virus grown in cell culture or by housing with lambs excreting BDV.

Molecular characterization of border disease virus strain Aveyron

Veterinary Microbiology, 2014
For the pestivirus border disease virus (BDV) at least seven major genotypes have been described (BDV-1-BDV-7). So far, complete genomic sequences have been reported for four BDV genotypes (BDV-1-BDV-4). In this study we report the entire genomic sequence of the noncytopathogenic (ncp) BDV-5 reference strain Aveyron. The viral genome encompasses 12,284

Progeny of sheep persistently infected with border disease virus

1991
Most lambs affected with border disease die early in life but those which survive gradually loose their body tremors and their fleece abnormalities become less clear. Seven female lambs persistently infected with border disease virus were reared to maturity and bred from when they were 2 to 3 years old.

Detection of a novel border disease virus subgroup in Tunisian sheep

Archives of Virology, 2004
Nine pestiviruses isolated from different batches of a contaminated Tunisian sheep pox vaccine and one Tunisian field ovine isolate of border disease virus (BDV) were studied at the antigenic and molecular levels. Seroneutralization tests were carried out on three vaccine isolates, the Tunisian field isolate and representative reference strains of the ...

Molecular Characterization of Border Disease Virus, a Pestivirus from Sheep

Virology, 1994
Three serologically different pestivirus strains isolated from sheep were selected for molecular analysis. cDNA and deduced amino acid sequences of the genomic regions encoding glycoproteins E1 and E2 were obtained from the three strains. A comparison with amino acid sequences of bovine viral diarrhea virus (BVDV) and classical swine fever virus (CSFV)

Border disease: Effect of virus administered intracerebrally to newborn lambs

Journal of Comparative Pathology, 1983
Six BVD antibody-free Dorset Horn lambs, less than 3-days-old, were infected by intracerebral inoculation of BD virus. Three of these lambs (Group I) were killed 7 days after inoculation (p.i.) and 3 (Group II) 21 days p.i. None of the lambs showed clinical signs of disease. Of the 5 lambs in which infection was established, 3 of Group I and 2 of Group

Replication of Border disease virus in ovine lymphocytes and monocytes in vitro

Research in Veterinary Science, 1994
Adherent and non-adherent mononuclear cells obtained from the peripheral blood of normal sheep supported the in vitro replication of a non-cytopathic and a cytopathic strain of Border disease virus (BDV) with no apparent cytopathic effects. There was a significant rise in virus titres in adherent mononuclear cells (monocyte) and non-adherent ...
