Tuberculosis is one of the most important infectious diseases worldwide. Mycobacterium bovis is the causative agent of bovine tuberculosis (BTB), an important animal pathogen with public health implications as it is a zoonosis. Currently, the diagnosis of BTB is based on the caudal fold test of the Tuberculin Skin Test (TST). Post-mortem bacterial culture is carried out to confirm the diagnosis, and then specific biochemical tests are performed for the characterization of the etiologic agent. Culture takes at least 4 to 8 weeks to develop. The diagnosis by molecular tests such as PCR can provide fast and reliable results, significantly decreasing the time of confirmation (from two months to two days), thus allowing the possibility of taking...
