PATHOLOGICAL ASPECTS OF CAPRINE PARATUBER CULOSIS

A pathological study performed in goats affected by paratuberculosis s howed the importance of the spread of lesions in the small intestine a nd that the lesions were scarce in the region of the ileocaecal valve (ICV). Similarly, the presence of paratuberculosis bacilli is rare in the colon. Consequently, to diagnose this disease in goats, the author s advise that multiple samples should be taken from the small intestin e without favouring the region of the ICV, traditionally chosen in cat tle. In addition, a comparative study, using histology as the referenc e method, indicated good diagnosis sensitivity with bacterial culture preparation from faeces and immunodiffusion in an agar medium. The sam e study in indicated the mediocrity of complement fixation as a diagno stic method for caprine paratuberculosis.
