Experimental investigations confirmed the identity of the conditions of Chamois papillomatosis and ecthyma contagiosum of sheep and goats. Like the ovinia derived ecthyma virus, the virus obtained from chamois could also be cultured in calf or pig testicular cell cultures. No differences have so far been demonstrated between the ovinia ecthyma contagiosum virus and virus strains derived from chamois. The importance of minor injuries for establishing the infection and developing the disease changes also finds expression in animal experiments. As opposed to present opinion, that ecthyma contagiosum only appears in chamois in winter, it is stressed that the disease may occur in game at any time of the year, even if it is less common and milder in form. This is confirmed by the demonstration of ecthyma virus in three chamois shot at the height of summer. Sheep, goats and chamois infected with ecthyma contagiosum virus from sheep or chamois were found to be immune to reinfection one year later.
