Oxidant-antioxidant imbalance in the experimental interstitial lung disease induced in sheep by visna-maedi virus. [PDF]
European Respiratory Journal, 1996 Infection of sheep by visna-maedi virus causes an interstitial pneumonitis similar to that associated with human immunodeficiency virus type-1 (HIV-1). Visna-maedi virus infection of alveolar macrophages leads to their activation. In this study we determined whether an imbalance in oxidant-antioxidant activity may be involved in the pathogenesis of the

Investigation, management and control of a maedi outbreak in Norway in 2019-2020 [PDF]
Acta Veterinaria ScandinavicaBackground Visna-maedi is a notifiable disease in Norway, and eliminating the disease is a national goal. The import of sheep into Norway is very limited, and strict regulations apply to the movement of small ruminants between flocks and within defined ...

Pathological, molecular, and serological study of small ruminant lentiviruses in Jordan [PDF]
Veterinary World, 2022 Background and Aim: Maedi-visna is a chronic viral disease of sheep with worldwide distribution causing substantial economic losses to the small ruminant industry. Pneumonia and mastitis are the main manifestations of the disease.

Maedi-visna infection in Pomeranian Coarsewool Sheep in Germany: seroprevalence, environmental and genetic risk factors [PDF]
Frontiers in Veterinary ScienceSmall ruminant lentiviruses (SRLV) cause maedi-visna (MV), an incurable, wasting disease, affecting sheep worldwide. This study evaluated the seroprevalence of maedi-visna virus (MVV) in the native German sheep breed Pomeranian Coarsewool Sheep (RPL) and

Histogenesis of the pulmonary lesions in the course of visna maedi virus-induced pneumonia
Veterinary research, 1996 The major characteristic lesion observed following spontaneous infection of sheep by the prototype lentivirus, maedi-visna virus (MVV), is a lymphocytic intestitial pneumonia. Similar lesions may be observed with variable frequency following infection of other species by pathogenic lentiviruses, for example in children infected by HIV-1.
