title: Paratuberculosis: eradication, control and diagnostic methods.
abstract: At the beginning of the twentieth century, the dairy industry and cattle breeding organisations initiated a programme to control infectious diseases by means of a complex system of rewards and penalties. The history of programmes to control paratuberculosis in sheep, goats, and cattle in various countries is described. The vaccination of young animals (especially goats and sheep) seems to be an effective measure in the prevention of clinical paratuberculosis, although changes in management and hygiene practices are also important. A control programme for infectious cattle diseases has a number of phases (a life cycle) and different components. Two components are essential for success, namely, open and regular communication with farmers, veterinary practitioners, and other people involved, and a good registration and identification system for cattle, herds, and veterinary practitioners. The principles and different levels of control of paratuberculosis are discussed. The Dutch paratuberculosis programme is divided in two parts: an intensive programme based on test and cull and an extensive programme based on education. The intensive programme has ten herd status levels: 5 to 10 for non?suspect herds and 1 to 4 for infected herds or herds of unknown status. The higher the status, the greater the chance that a herd is free of paratuberculosis. An outline is given of the Dutch paratuberculosis programme. Diagnostic methods are summarised. Future developments regarding vaccination and control or acceptance of paratuberculosis are discussed.
