A non-systematic literature review approach was followed to search for focused available information on BTB control options using search engines such as Google scholars and PubMed with key phrases like control of BTB, control of TB in cattle and control of zoonotic TB. The generated articles were read in-depth for the targeted information and the citations in the articles were further referred when deemed necessary. FG, GEA, KM, TB, MM, and GA designed the study. The stakeholders agreed that BTB is a major problem and that the prevalence is particularly high in dairy herds with exotic cattle breeds and their crosses kept under semi intensive or intensive production system in urban and peri-urban dairy farming. Currently, there are several ongoing efforts to address zoonotic BTB to end the global TB epidemic by 2030 globally (4). Whilstonce TB was the most prevalent infectious disease of cattle and swine in the United States, it has now been nearly eradicated from livestock in the US through a cooperative state-federal program. Table 4. Learn about past and current bovine TB research and development projects funded by Defra. Improved understanding and conscientious usage of veterinary medicines. It is acid-fast organism. The national BTB prevalence estimate was 5.8% in individual cattle, with higher prevalence of 21.6% in exotic breeds and their crosses and 16.6% in herds kept under intensive and semi-intensive production systems in urban and peri-urban areas (13). inch area in the middle of neck without any cuts and abrasion.

Despite significant knowledge gaps regarding the real impact of BCG vaccination on the incidence of BTB and the inability to distinguish between infected and vaccinated cattle using purified protein derivative (PPD) skin test (19, 20), recent experimental studies have indicated the significance of vaccinating cattle with BCG vaccine in reducing the prevalence, progression and severity of BTB and recommended BCG vaccine as a valuable tool in the control of BTB (21, 22). Licences and authorisations issued by Natural England to permit local farmers and landowners to remove badgers to prevent the spread of bovine TB. For instance, Australia is among the few countries that eradicated BTB successfully (25) while USA is on the verge of controlling BTB through tracing of infected herds identified through meat inspection, followed by test and slaughter program (26). A model of the transmission and spread of bovine tuberculosis in Britain suggests that controlling the epidemic will require large-scale cattle slaughter or a major rethink of combined control .
