TL;DR: This paper discusses three important questions in the field of SRLVs: routes of transmission, consequences of infection and potential role of eradication programmes at either a European or local level, according to the situation in each country or region.

Pathogenesis of visna. I. Sequential virologic, serologic, and pathologic studies.
TL;DR: Detailed base line data on visna infection is provided to suggest some of the mechanisms responsible for the persistence of infection and for the slowness and irregularity of disease occurrence, and form the basis for further experiments on the role of immunologic mechanisms in the pathogenesis of this slow infection.

Journal Article
Pathogenesis of visna. II. Effect of immunosuppression upon early central nervous system lesions.
TL;DR: Several different ways in which suppression could modify the immune response to visna virus are suggested, including a reduced number of virus isolations from peripheral lymphoid tissue, presumably reflecting the lympholytic effect of treatment.
Journal ArticleDOI
Antigenic Drift in Visna: Virus Variation During Long-term Infection of Icelandic Sheep
TL;DR: Although variant viruses are encountered at considerable frequency during long-term infection of Icelandic sheep, the variants usually do not replace the infecting strain and antigenic drift does not appear to be essential for virus persistence or for the development of clinically evident CNS lesions.
