Eradication programme for caseous lymphadenitis in goats in the Netherlands.

Abstract

The eradication programme for caseous lymphadenitis in goats, which has been used in the Netherlands since 1988, is described. In January 1996, all of the 53 goat herds, amounting to about 13 000 goats older than one year, of the Amalthea cooperative (to which most of the Dutch goat farmers belong) were certified free from caseous lymphadenitis. Success of the programme is due to: identification and registration of all goats; use of a serological test with a high specificity and sensitivity (a double-antibody sandwich ELISA with a herd specificity and sensitivity of nearly 100%); disposal of affected or reacting goats; and awareness of participating farmers that the programme is economically justified. Recently 3 goats on a farm not in the cooperative were found to have Corynebacterium pseudotuberculosis abscesses, 2 were negative and one doubtful in the ELISA and an immunoblot assay. Reasons for the failure of the ELISA, the first in goats since 1988, are under investigation.
