maedi-visna (mv) virus and caprine arthritis encephalitis (cae) virus known as small ruminant lentiviruses (srlvs) cause chronic diseases in susceptible animals. the main reservoirs of these viral agents are sheep and goat. in sheep, mv virus causes a disease as the same name of the virus. this is the first seroprevalence survey of srlvs in sheep population of khorasan-e-razavi province in iran...

Multisystemic disease caused by Small Ruminant Lentiviruses (SRLV) in sheep and goats leads to production losses, to the detriment of animal health and welfare. This, together with the lack of treatments, has triggered interest in exploring different strategies of immunization to control the widely spread SRLV infection and, also, to provide a useful model for HIV vaccines. These strategies inv...

Based on available sequence data, a phylogeny of small ruminant lentiviruses (SRLV) was established for env, pol, gag and LTR fragments using maximum likelihood, neighbour-joining and minimum evolution reconstruction techniques. To reconstruct topologies as accurately as possible, phylogenetic parameters like base composition, percentage divergences, kappa, the gamma shape parameter alpha and c...
