[Evaluation of two ELISA techniques for the diagnosis of bovine paratuberculosis].

A sensitivity of 50% and a specificity of 98% were obtained in the evaluation of a serological method (commercial absorbed ELISA, Commonwealth Serum Laboratories, Parkville, Australia) for the diagnosis of paratuberculosis. The population used in the study consisted of 20 infected, suspect and non-infected herds from the region of the Plateau de Diesse. Another evaluated non-absorbed ELISA test had a sensitivity of 30% and a specificity of 91%.
