Pestivirus apparent prevalence in sheep and goats in Northern Ireland: A serological survey
Veterinary Record, Volume 188, Issue 1, January 2021., 2021 Abstract Background: Bovine viral diarrhoea virus (BVDV) and border disease virus (BDV) can cause significant health problems in ruminants and economic impacts for farmers. The aim of this study was to evaluate pestivirus exposure in Northern Ireland sheep and goat flocks, and to compare findings with a previous study from the region. Methods: Up to 20

Substructures and Polypeptides of Visna Virus [PDF]
Journal of Virology, 1974 The protein of Visna virus, disrupted by 8 M guanidine hydrochloride and heating, was resolved into 10 polypeptides by agarose gel column chromatography in 6 M guanidine hydrochloride. Two of the peaks contained glycopolypeptides. Nonidet-disrupted virions were resolved into two fractions by potassium tartrate gradient centrifugation, with densities of

Vaccination delays maedi-visna lentivirus infection in a naturally-infected sheep flock
BMC Veterinary Research, 2013 Background The Maedi-Visna (MV) lentivirus causes two slowly progressive eventually fatal diseases of sheep, Maedi, a progressive interstitial pneumonia, and Visna, a progressive demyelinating disease of the central nervous system.

Visna Virus Meningoencephalomyelitis in Goats [PDF]
Acta Veterinaria Scandinavica, 1981 A progressive paresis was encountered in herds of Swedish goats. The symptoms developed during a period of weeks or months, and were initially often seen as a weakness of the hind limbs before the animals became paralytic. The development and the histopathological lesions of the disease in the GNS and the lungs were similar to those of visna in sheep ...

PREVALENCE OF MAEDI-VISNA IN SHEEP HERDS
Archives of Veterinary Medicine, 2008 Progressive sheep pheumonia and maedi are terms that denote chronic virus sheep disease. Maedi-visna virus causes a disease named visna, which is a disease of nervous system with the symptoms of paresis and paralyses.

Experimental Visna in Icelandic Lambs [PDF]
Acta Veterinaria Scandinavica, 1977 Icelandic lambs were inoculated intracerebrally with visna virus at 10 days of age and sacrificed 22–25 days after infection. Virus was isolated from all 5 inoculated animals, and pronounced periventricular lesions, typical of early visna, were seen in the 3 lambs with the most widespread infection.

Epidemiological survey for visna-maedi among sheep in northern prefectures of Japan [PDF]
Veterinaria Italiana, 2011 Ovine sera collected from the northern Prefectures of Hokkaido, Iwate and Aomori in Japan, were examined for the presence of antibodies against visna-maedi virus using the agar gel immunodiffusion test and enzyme-linked immunosorbent assays.
