[Paratuberculosis eradication programs in Northrhine-Westfalia].

Since 1993 a voluntary eradication program for bovine paratuberculosis is established in Northrhine-Westfalia. After an effectivity control of the serological diagnostics it is combined with the fecal culture since August of 2000. Parallel use of both methods is necessary for a successful eradication. It could be monitored that a high percentage of the newly bought cattle in the herds participating in the eradication program was considered positive. Since paratuberculosis eradication is time and cost extensive besides intensive eradication programs the spread of the disease must be stopped.
