Progeny of sheep persistently infected with border disease virus
1991Most 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.

Border disease: Tissue culture studies of the virus in sheep
American Journal of Veterinary Research, 1982SUMMARY 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.

Bovine virus diarrhoea-mucosal disease and Border disease in Egypt
Revue Scientifique et Technique de l'OIE, 1992In Egypt, bovine virus diarrhoea-mucosal disease (BVD-MD) was initially detected as the result of a serological survey of cattle and sheep, using the serum neutralisation test. In 1970, the causal pestivirus was isolated from bovine calves and buffalo calves with pneumonia and enteritis. Mixed viral infections were also prevalent.

Border disease: Effect of virus administered intracerebrally to newborn lambs
Journal of Comparative Pathology, 1983Six 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

Border disease: virus persistence, antibody response and transmission studies
Research in Veterinary Science, 1981Three groups of five and one group of four oestrus-synchronised sheep were inoculated with Border disease (BD) virus at 52 +/- 2 days after their first service. Transmission of virus to offspring as demonstrated by virus isolation, detection of viral antigen and, or antibody response occurred in 12 of 19 sheep and probably in four others which aborted ...

Detection of a novel border disease virus subgroup in Tunisian sheep
Archives of Virology, 2004Nine 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 ...

Arachidonic acid immunoregulation in lambs persistently infected with border disease virus
Comparative Immunology, Microbiology and Infectious Diseases, 1993To evaluate arachidonic acid-related immunoregulatory mechanisms during long-term persistent pestivirus infection, we measured plasma contents of leukotriene C4 (LTC4), prostaglandin D2 (PGD2) and their plasma fatty acid (FA) precursor, arachidonic acid (AA), in six lambs with congenital border disease (BD).
