Antigenic variation in visna virus

Cell, 1979
Two antigenic variants of visna virus were isolated sequentially from a single sheep inoculated with a plaque-purified strain of virus designated 1514. The genetically stable variants, LV1-1 and LV1-4, are of two classes: LV1-1 is partially neutralized by antibody to the inoculum strain 1514, while LV1-4 is not neutralized by antibody to 1514.

Visna Virus Infection of American Lambs

Science, 1974
Random-bred fetal and 4-week-old American lambs, inoculated intracerebrally with visna virus, developed a persistent infection in the brain and sometimes in the lung. The pathologic changes present in these lambs were similar to the early lesions of visna in Icelandic sheep, thus providing a possible model for the study of virus-induced demyelinating ...

Visna virus RNA synthesis

Journal of Virology, 1977
Visna is a classical slow infection in which virus characteristically persists in the face of the host immune response. The agent of this disease belongs to the retravirus group. The persistence of infection and the slow spread of virus are at least in part a consequence of restriction of the expression of virus genetic information in tissues of an ...

Concern over maedi visna breakdowns

Veterinary Record, 2014
WE 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 ...
