[automatically translated] The Arthritis-Viral Encephalitis Caprina is an infectious disease reported for the first time in 1974; the causative agent has been isolated only in 1979: it is a virus of the family Retroviridae, genus Lentivirus. The virus is mainly spread through colostrum, milk (during milking) and, to a lesser degree, through blood, saliva, sputum, vaginal secretions. The disease may progress to form subtle and tends to be underestimated in the infected farms. The clinical forms in adult animals are in the form of arthritis and / or mastitis, while in young animals, in which the evidence is even more rare, is observed clinical symptoms referable to encephalitis. The CAEV, whose presence has been reported in all continents, is also in Sicilian goat farms and currently been repeatedly diagnosed is one of the largest goat breeding problems, especially in cosmopolitan dairy breeds (Saanen, Alpine Camosciata) newly introduced in Sicily by the serious economic damage which results (reduction in production milky, up to 25-30%; reduced immunity with increased susceptibility to diseases; more business management costs; lower longevity and productive career of animals affected by the disease; disorders in the development of young people). Recent prevalence studies, based on a sample of goat farms in the provinces of Agrigento and Palermo, the percentage distribution of the disease is estimated respectively at around 60.6% and 63.3%. This work represents the operational proposal drawn IZS of Sicily, in cooperation with the Reference Center and ASP competent in order to activate a control program and voluntary eradication against the Arthritis Encephalitis Caprina (CAEV) goat at some companies sensitive to the problem. The three companies that have asked for the activation of this plan should, through the adoption of preventive measures laid out, before reducing the percentage of positivity in the company and then point to the complete eradication. This objective can be achieved through different strategies and operational procedures that will have to take account of the structures, the type of farming and the percentage spread of the disease within the company.
