Therefore, the epidemiologic investigation included the livestock he was in contact with, particularly the herd of sheep and goats he was currently managing. So why bother, if M. caprae is not an enigma for diagnostic TB tests and if resistance against first-line drugs is a rarity with M. caprae? Bobadilla-del Valle M, Torres-Gonzalez P, Cervera-Hernandez ME, Martinez-Gamboa A, Crabtree-Ramirez B, Chavez-Mazari B, Ortiz-Conchi N, Rodriguez-Cruz L, Cervantes-Sanchez A, Gudino-Enriquez T, et al. In this context, the aim of this study was to describe the sociodemographic, epidemiological, and clinical characteristics, and to determine the factors associated with M. bovis disease as compared with M. tuberculosis. Most of the data available on the presence of M. bovis-induced TB in India are based on observational studies conducted on a small number of suspected TB patients. Additionally, changes in the definition of high-prevalence zones regarding BTB have occurred through time due new requirements for cattle export; therefore, we were unable to compare this variable through the study period and this may also have accounted for the lack of association. Multidrug resistance (MDR) was defined as resistance to at least both rifampicin and isoniazid. In recent years, there is a renewed interest for the control of bTB to minimize human infection worldwide. Google Scholar.

After the 1960s, the number of human cases of tuberculosis (TB) caused by Mycobacterium bovis decreased significantly in England, Wales, and Northern Ireland, co-inciding with widespread implementation of milk product pasteurization and national bovine TB control programs (1-3).During the past 2 decades in these 3 countries, an average of 30 cases of M. bovis in humans occurred annually . In such situations, patients with M. bovis-induced TB receive inadequate treatment which may lead to adverse consequences on the management of TB patients60 and may even induce the emergence of drug resistance to anti-TB drugs.
