An increase of mortality was observed in the chamois of the Pyrenees in 2001 and 2002, with a clinical picture never observer before. Virological analysis detected a Pestivirus never described before, that forms a separate branch within the Border Disease Virus cluster. In 2005, three new outbreaks have been described in different areas of the Pyrenees. Mortality was extraordinary high (93%), which lead to a demographic collapse of the population. The aims of this project are: 1. To study the epidemiology of the infection in the chamois population of the affected areas and in the unaffected populations nearby. 2. To study the epidemiology of the infection in other wild ungulates (mouflon, roe, red deer, fallow deer and wild boar) that share the habitat with chamois in the affected areas. 3. To study the epidemiology of the infection in domestic ungulates (bovine, ovine and caprine) that share the habitat with chamois in the affected areas. 4. Experimental infection of sheep with the Pestivirus isolatd from the affected chamois. The results will allow to determine the epidemiological status of the infection in the chamois population and if it has been transmitted to other wild or domestic species. The experimental infection in sheep as a model, in case of succeed, will fulfil the main criteria to confirm that the isolated Pestivirus is the cause of the epidemic in chamois. Altogether will help to apply suitable management measures for the conservation of the species.
