Mucosal vaccination with an attenuated maedi–visna virus clone
Vaccine, 2005Four sheep were infected intratracheally with an attenuated molecular clone of maedi-visna virus (MVV). All four became infected. Ten months later these sheep were challenged intratracheally with a genetically similar but pathogenic clone of MVV. Four unvaccinated sheep were infected simultaneously. All sheep became infected by the challenge virus. The

Maedi-Visna Virus Detection in Ovine Third Eyelids
Journal of Comparative Pathology, 2003Maedi-visna is a systemic disease of sheep caused by a lentivirus, maedi-visna virus (MVV), which mainly affects the lungs and central nervous system but may also affect the mammary glands, joints and other tissues. The aim of the present study was to determine whether the third eyelid was affected in cases of systemic infection.

The occurrence of maedi-visna virus in Lebanon.
Revue scientifique et technique (International Office of Epizootics), 2017Maedi-visna (MV) is a chronic viral disease prevalent in adult sheep that is caused by a virus belonging to the small ruminant lentivirus group (SRLV). This disease is considered to affect the international trade of sheep and is classified in the World Organisation for Animal Health (OIE) list of notifiable animal diseases.

The biology of maedi-visna virus—An overview
British Veterinary Journal, 1993This review aims to summarize the current understanding of the biology of maedi-visna virus (MVV), the prototype virus of the family lentivirinae. The paper provides a short overview of the historical background to the discovery of MVV. Detailed descriptions of the structure and organization of the MVV genome and of the virion encoded polypeptides are ...

Immune response to maedi-visna virus
Frontiers in Bioscience, 2007The ovine maedi-visna virus (MVV) was the first lentivirus to be isolated and characterized 1957 in Iceland. MVV leads to a life-long, persistent infection with slow development of lesions in the lung and the central nervous system (CNS). The main target cells of MVV are of the monocyte/macrophage lineage and it does not infect T-lymphocytes or cause ...

Ultrastructural studies on Maedi-Visna virus
Archives of Virology, 1980Ultrastructural studies of Maedi-Visna virus (MVV) particles isolated from tissue culture fluids of MVV-infected cells as well as cultured cells infected with MVV were performed. MVV particles aree bounded by an envelope with projections loosely attached to its surface.

Cross Neutralization of Maedi‐Visna Virus Strains*
Zentralblatt für Veterinärmedizin Reihe B, 1984SummaryCross‐neutralization of four Norwegian, two Icelandic and one Danish maedi‐visna virus strains was carried out with a panel of sheep antisera. Sheep antiserum to visna virus glycoprotein was the only one that did not show cross‐neutralization. The other sera showed varying degrees of cross‐reactivity.

DNA Vaccines Against Maedi–Visna Virus
2016Maedi-visna virus (MVV) is an ovine retrovirus of the Lentivirus genus, responsible for a chronic and progressive disease of sheep with a high prevalence all over the world. Therefore, measures aiming at the control of MVV infection are necessary, and the development of DNA vaccines may be the ideal approach.

Maedi-visna virus persistence: Antigenic variation and latency
Comparative Immunology, Microbiology and Infectious Diseases, 2017Maedi-visna virus (MVV), a lentivirus of sheep, shares with other lentiviruses the ability to establish a lifelong infection. In this study five sheep were infected intravenously with MVV and housed together with a number of uninfected sheep for natural transmission.
