    Abstract:
    Tuberculosis in goats (caused by Mycobacterium caprae and M. bovis) has become a significant concern in recent years because of its high prevalence in certain caprine herds in Spain and other European countries, and also due to the potential transmission to other animals and human beings. In the present study, a transthoracic model of tuberculosis infection was performed on goats. Animals were selected based on the serological response used to detect paratuberculosis in goats (negative and positive results). The kinetics of the immune response was evaluated using the interferon-gamma (IFN-gamma) assay, skin tests and serology of paratuberculosis during nine months post-challenge. At the end of the study the animals were necropsied, tuberculosis-lesions were scored and culture (M. caprae and M. avium subsp. paratuberculosis) was performed to determine the true infection status. Animals were positive to the IFN-gamma assay 15 days post-challenge and the values were fluctuating throughout the study. A varied performance of the assay was observed between tuberculosis and tuberculosis-paratuberculosis mixed infection regarding both the number of positive results and the OD values obtained after stimulation with bovine and avian PPDs. Furthermore, the single intradermal comparative cervical tuberculin test did not detect all M. caprae-infected animals. At necropsy, a positive correlation between pathology score and bovine PPD specific IFN-gamma response was found.
