|description= ''Ovine Maedi Visna Virus'' (SA-OMVV) is a sheep lentivirus found in South Africa and similar to Visna viruses of sheep. This genomic structure of this retrovirus is 9.2 Kb in size including LTRs of 499 nt (pro-5´LTR-R/U5 and pro3´LTR-U3/R of 152 nt and 347 nt, respectively. The internal region displays a Primer Binding Site (PBS) complementary to a tRNA<sup>Lys1,2</sup>, Open Reading Frames (ORFs) for ''gag'', ''pol'' and ''env'' genes characteristic of retroviruses, ''tat'' and ''rev'' and ''orfq'' (''vif'' or ''sor''), which are three accessory genes common in other lentiviruses,an ''orfw'' also displayed but corrupted in other sheep lentiviruses, and a Polypurine Tract (PPT) adjacent to the 3′LTR ([[Literature:66008|Saltarelli ''et al.'' 1990]]; [[Literature:61531|Querat ''et al.'' 1990]]). As other non-primate lentiviruses, this retrovirus also displays between the RNase H and the INT an ORF coding for a dUTPase (dU) similar to that observed in betaretroviruses, N-terminal to the PR domain ([[Literature:20174|Elder ''et al.'' 1992]]; [[Literature:58348|Payne and Elder 2001]] and references therein).
