Extensive rearing hinders Maedi-Visna Virus (MVV) infection in sheep [PDF]
Veterinary Research, 2006 Maedi-Visna Virus (MVV) seroprevalence and its relationship with housing and mode of rearing of replacement ewe-lambs was investigated in 38 non-randomly selected sheep-flocks in Spain. They included extensive lamb-producing Manchega cross-bred flocks raised almost permanently at pasture, semi-intensive Latxa dairy flocks housed 2-8 months/year and ...

Immunogenetics of Small Ruminant Lentiviral Infections
Viruses, 2014 The small ruminant lentiviruses (SRLV) include the caprine arthritis encephalitis virus (CAEV) and the Maedi-Visna virus (MVV). Both of these viruses limit production and can be a major source of economic loss to producers.

Selection of antigenic variants in maedi–visna virus infection
Journal of General Virology, 2002 In order to analyse the pattern of sequence variation in maedi–visna virus (MVV) in persistently infected sheep and to answer the question of whether antigenic variants are selected in a long-term MVV infection, an 87 bp variable region in theenvgene of ten antigenic variants and 24 non-variants was sequenced.
