Concern over maedi visna breakdowns
Veterinary Record, 2014WE would like to raise our concerns with veterinary colleagues over an apparent increase in the number of flocks in the maedi visna (MV) accreditation scheme that have had a breakdown with MV infection. Most of the blood testing for the MV accreditation scheme takes place during the summer months; however, so far this year there have been nine ...

The synthesis and structure of visna virus DNA
Virology, 1979Abstract The synthesis of proviral DNA of visna virus was measured at various intervals after inoculation of sheep cell cultures at multiplicities of 0.3, 1, and 10 PFU/cell. The DNA from the infected cells was fractionated by the Hirt procedure into low (Hirt supernatant) and high (Hirt precipitate) molecular weight DNAs, and each fraction was ...

Visna virus was originally recognized in the 1930s as the etiologic agent of an unusual and sporadic outbreak of a transmissible neurologic disease that simultaneously appeared with several chronic pneumonic diseases affecting sheep in Iceland (Sigurdsson, 1954, 1957; Sigurdsson and Palsson, 1958). Visna means “wasting” in Icelandic and became the name

Maedi-Visna and Ovine Progressive Pneumonia
Veterinary Clinics of North America: Food Animal Practice, 1997Maedi-Visna and ovine progressive pneumonia are disease of sheep that are caused by ovine lentivirus and characterized by chronic inflammation of the lungs, mammary glands, joints, and central nervous system. Although tremendous progress in research has led to a better understanding of the pathogenesis of these diseases, many questions still remain ...

Maedi - Visna. Pathology and Pathogenesis
1990Infection of sheep with maedi-visna virus (MVV) causes a multi-organ disease, i.e. encephalitis, pneumonia, mastitis and arthritis. Both the spectrum of organ changes and the character of pathological lesions are similar to that observed in the related lentiviral infection of goats. The tissue tropism of infection with human immunodeficiency virus (HIV)

El maedi o neumonía progresiva ovina es la principal manifestación clínica de la infección por el virus maedivisna. Aunque la enfermedad se conocía desde antiguo en varios países (Zwoegerziekte, bouhite, ovine progressive pneumonia, etc.), sólo su entrada y rápida expansión en Islandia durante los años treinta generó el interés científico y práctico ...
