In several countries, bovine tuberculosis, caused by Mycobacterium bovis, is an economic and public health problem. Worldwide disease eradication programs are implemented with policies based on tuberculin testing and slaughter of reactive animals. However, little is known about the costs and the effectiveness of the eradication policies. We evaluated the cost-effectiveness of bovine tuberculosis diagnostic protocols on a multidisciplinary approach, applied in a naturally infected herd. Regarding the cost-effectiveness analysis (C/Ef) of ante-mortem diagnostic protocols, the Cervical Comparative Test (C/Ep=4.68), when used alone, is the diagnostic protocol most cost-effective for a naturally infected herd. For post-mortem confirmatory diagnostic, the histopathology (C/Ep=17.47) associated with the Cervical Simple Test and Cervical Comparative Test was the most cost-effective choice for the animals studied in this herd. However, the only diagnostic protocol that was able to identify 100% of the infected animals was the ELISA associated with the IFN test. |
