Small ruminants Lentivirus infection in the region of Trás-os-Montes, Portugal: preliminar results. In XXI Middle European Buiatrics Congress. Olsztynhttp://hdl.handle.net/10198/27968Small ruminant lentiviruses (SRLVS) are a group of viruses responsible for Maedi-Visna in ovine and for Caprine Arthritis Encephalitis in caprine species. Theses diseases result of progressive and chronic infections which affect animal health as well as are one of the major causes of severe economic loss. In the north-eastern region of Portugal (Trás-os-Montes) small ruminant farming has a great economic and social value. On current days, in Portugal, there is few information about SRLV infection. The main aim of this research is to quantify seroprevalence as well as risk factors associated to lentivirus infection of small ruminant in this region of Portugal.engSRLVRisk factorsResearch Subject Categories::FORESTRY, AGRICULTURAL SCIENCES and LANDSCAPE PLANNING::Animal productionSmall ruminants Lentivirus infection in the region of Trás-os-Montes, Portugal: preliminar resultsconference poster
