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.

Maedi-visna virus as a model for HIV

Icelandic Agricultural Sciences, 2018
Mæði-visnuveira sýkir kindur og veldur aðallega lungnabólgu (mæði) og heilabólgu (visnu). Veiran er lentiveira og er náskyld alnæmisveirunni HIV. Veirurnar eiga margt sameiginlegt, svo sem skipulag erfðaefnis, virkni og gerð veirupróteina, fjölgunarferli, viðbrögð hýsils við sýkingu og dvalasýkingu, sem hýsillinn losnar aldrei við.

Ovine TRIM5α can restrict visna/maedi virus [PDF]

, 2012
The restrictive properties of tripartite motif-containing 5 alpha (TRIM5α) from small ruminant species have not been explored. Here, we identify highly similar TRIM5α sequences in sheep and goats. Cells transduced with ovine TRIM5α effectively restricted
