The definition of border disease: problems for the diagnostician

Veterinary Record, 1979
Inocula derived from two sources of typical border disease (BD) and designated BP-77 and H-77 respectively, were prepared and injected into pregnant ewes of four breeds. The BP-77 inoculum produced higher serum neutralising antibody titres to the cytopathic BD virus than to the NADL strain of bovine virus diarrhoea virus. Only typical BD occurred among

Border disease in goats in Norway

Research in Veterinary Science, 1982
Border disease was diagnosed in a flock of 91 goals in Norway. The clinical signs and histopathological changes in a kid were similar to those found in cases of natural disease in lambs and in kids from experimentally infected goats. Border disease virus neutralising antibodies were found in 43 per cent of goats in the flock.

Immunization against border disease

Journal of Comparative Pathology, 1980
Abstract Vaccination experiments with live and inactivated virus preparations in complete and incomplete Freund's adjuvant and with ds-RNA were conducted in sheep subsequently challenged intraperitoneally or intramuscularly with a suspension of Border disease (BD) infected lamb brain.

Border Disease in Sheep

Veterinary Clinics of North America: Food Animal Practice, 1995
The current knowledge on border disease in sheep is reviewed. This is a congenital and teratogenic disorder induced by pestivirus. The history, etiology, epidemiology, clinical aspects, and pathologic lesions at postnatal and intrauterine infections (as well as in congenitally affected animals), pathogenesis, immunity, diagnosis, and control and ...

Vectorborne diseases: no respecters of borders

Veterinary Record, 2016
Vectorborne diseases have been very much in the news in 2016, with, for example, the outbreak of Zika virus resulting in a number of high‐profile athletes withdrawing from this year's Olympic Games in Brazil. In the UK, the threat of bluetongue virus arriving by windborne midges from France remains real. In his latest update for

Vertical transmission of Border disease infection

Journal of Comparative Pathology, 1981
Abstract Border disease (BD) was produced in lambs following artificial insemination of ewes with semen from persistently infected but apparently recovered cases of BD. The infection produced in this way appeared to persist in the genitourinary tract of some ewes for up to 32 days despite the concurrent production of circulating neutralizing ...

Border disease in a flock of Minnesota sheep

Journal of the American Veterinary Medical Association, 1982
SUMMARY A flock problem affecting newborn lambs on a Minnesota farm was investigated. The lambs had hairy fleece and rhythmic tremors, and were unthrifty. Histologic examination revealed hypomyelinization of the cns and hypertrophy of primary follicles in the skin. A virus antigenically related to bovine viral diarrhea virus was isolated.

Copper metabolism in experimental Border disease

Veterinary Record, 1976
The proposal that hypocupraemia and hypocuprosis are characteristic manifestations of Border disease and of aetiological significance has been investigated. Mean plasma copper concentrations in 65 affected and 47 unaffected lambs were similar and in a controlled experiment, plasma and tissue copper concentrations tended to be higher in affected lambs ...

Border disease: persistant infection with the virus

Veterinary Record, 1979
Two genetically related sheep that produced border disease-affected lambs from successive pregnancies were identified. These sheep, and some of their progeny, were found to be persistently infected with a virus antigenically related to bovine virus diarrhoea/mucosal disease virus.

Mechanisms of natural transmission of Border disease

Journal of Comparative Pathology, 1980
Abstract In the field, lambs severely affected with Border disease die in early life. Experimentally 2 flocks of severe clinical cases were reared to maturity and bred from for up to 4 years. It has been shown that such animals remain persistent excretors of virus and can be immunologically tolerant. They readily transmit the infection to susceptible
