Small Ruminant Lentivirus causes a chronic lifelong, multisystemic
diseases in sheep and goats with or without clinical manifestation. Maedivisna
virus (MVV) and Caprine arthritis encephalitis virus (CAEV) are often
considered together as small ruminants lentivirus (SRLV) because of
their phylogenetic correlation and the interspecies transmission between
sheep and goats.
During a fi ve-year period, from 2014 to 2018, a monitoring on male
animals (rams and bucks) used for breeding was conducted with the aim
to determine antibodies against SRLV using ELISA serological method. In
total, serum samples from 5,039 animals were analysed and the overall seroprevalence
of 5.59% was found. Th e seroprevalence for the whole period
was 5.15% in male animals while in female animals it was 6.15%. During
the whole 2014-2018 period, seroprevalence was 4.52% in rams, 17.61% in
bucks, 1.14% in sheep and 12.57% in goats. Compared to earlier studies and
within the study period, the seroprevalence for SRLV actually decreased in
rams and bucks. Th e study results show that annual monitoring program is
very important and has to be conducted in the future in order to keep the
disease under control. Th e program helps in raising awareness and familiarizing
owners with SRLV and the importance of breeding seronegative
animals.
