Scope note: Especie de LENTIVIRUS, subgénero de LENTIVIRUS OVINO-CAPRINO, que puede producir neumonía crónica (maedi), mastitis, artritis y encefalomielitis (visna) en ovejas. Maedi es una neumonía progresiva de las ovejas que es similar a jaagsiekte (ADENOMATOSIS PULMONAR OVINA). Visna es una leucoencefalomielitis desmielinizante de las ovejas que se asemeja a carneros que es similar pero no igual a la SCRAPIE.
