[Experiences in the eradication of Brucella ovis infections in sheep in Tyrol].

Since 1993 a campaign to eradicate Brucella ovis from sheep in Tyrol, using a combination of serological test and culling, is underway. During the pilot survey from 1990 until 1992 out of 812 tested rams, 85 (10%) seroreactors were identified by ELISA. In the year 1995 2263 rams were tested by ELISA, 80 (3.5%) seroreactors could be identified. As the topographical distribution shows the disease is still concentrated in defined areas. The paper discusses the values of the serological tests and reports about the experience in eradication.
