  Detection, identification, and differentiation of members of the MTB complex rely on specificity, sensitivity, and accuracy of the methods that have been developed since the decades of the ’90s. Despite this, still, in endemic areas of developing countries tuberculin field test as well as conventional techniques (histopathology and bacteriology) are performed due primarily to the costs and availability. Therefore, it is an urgent need to have a routine assay to boost field test (false positive and negative tests) in live cows while avoiding the unnecessary sacrifice of animals. To this end, in the present work, we designed a dual experimental strategy that can be used as a routine assay for the M. bovis or M. tuberculosis detection through PCR mediated amplification of RD’s. DNA can be prepared from fast-growing colonies (7 to 8 days) or from homogenized tissue, nasal exud.. View more»
