Caprine arthritis-encephalitis (CAE) is a viral disease of goats caused by small ruminant lentivirus (SRLV) of Retroviridae family. CAE is widespread worldwide and most infected animals remain subclinically affected. However, seroprevalence of CAE virus in Lithuania requires more study. The purpose of this study is to determine the seroprevalence of CAE in Lithuania. Dairy goat farms having at least 10 animals (older than 6 months) were selected by the voluntary participation in this research from different regions of Lithuania. Goats for testing were selected randomly or by presence of clinical symptoms of arthritis or respiratory disorders. 10-15 whole blood samples were collected from each farm using blood collection tubes with clot activator. Blood serum was investigated by enzyme-linked immunosorbent assay (ID Screen® MVV/CAEV Indirect screening test). Results of serological tests were used for statistical analysis. A total 172 blood serum samples from goats were investigated by ELISA test. It was shown that 38 (22.1%) of samples were seropositive (95% CI: 16.5-28.9). It was determined that in different farms the seroprevalence of CAE was significantly variable. The range of seroprevalence in tested blood samples of different farms was broad: from 0 to 100% . In 9 of 15 investigated goat farms there was at least one seropositive animal, those herds were considered CAE virus infected. The study has shown that CAE virus infection is quite common and endemic in Lithuania. The further and more detail study of CAE virus infection distribution in Lithuania goat farms should be performed.
