Phylogenetic analysis of small ruminant lentiviruses.
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...
متن کاملImmunization against Small Ruminant Lentiviruses
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...
متن کاملSerological study of small ruminant lentiviruses in sheep population of Khorasan-e-Razavi province in Iran
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...
متن کاملPost-entry blockade of small ruminant lentiviruses by wild ruminants.
Small ruminant lentivirus (SRLV) infection causes losses in the small ruminant industry due to reduced animal production and increased replacement rates. Infection of wild ruminants in close contact with infected domestic animals has been proposed to play a role in SRLV epidemiology, but studies are limited and mostly involve hybrids between wild and domestic animals. In this study, SRLV seropo...
متن کاملInterspecific transmission of small ruminant lentiviruses from goats to sheep
This study was conducted in order to evaluate the transmission of caprine lentivirus to sheep using different experimental groups. The first one (colostrum group) was formed by nine lambs receiving colostrum from goats positive for small ruminant lentiviruses (SRLV). The second group (milk group) was established by nine lambs that received milk of these goats. Third was a control group, consist...
