It is a very rare human disease but can acquired by direct contact with infected animals. Khosravi AD, Alami A, Meghdadi H, Hosseini AA. Regional differences in herd incidence were not significant from 2014 to 2017 because cattle trades between regions are common in South Korea. A Defra spokesperson added: "We are currently looking further at how the disease can be controlled in these animals.". Bovine tuberculosis: An old disease but The objective of this study was to assess the IFN- assay in terms of diagnostics and as a nationwide Frontiers | Introduction and Application of the Interferon- Agreement between results of the IFN- assay and CFT for 492,068 cattle tested from 2014 to 2017 is shown in Table 3. Some believe this may be due to lesions on the lungs having little adverse effect because the animals can live at such high altitudes in the Andes. Therefore, it is possible that the diagnosis of bTB by the IFN- assay is likely to be influenced by co-infection or pre-sensitization, although additional investigations are needed to confirm this. In 2021, the largest number of new TB cases occurred in WHOs South-East Asian Region (46%), followed by the African Region (23%) and the Western Pacific (18%).

PCR products were analyzed using agarose gel electrophoresis with a 1.5% agarose gel. In South Korea, although the control program based on the CFT and meat inspection has been conducted over the last 50 years since the first bTB detection in 1913, bTB is still regarded as an endemic disease, which greatly affects cattle husbandry. These two companies don't provide the potency of PPD-B as international unit (IU) but as protein concentration (CAVAC-0.2 mg/0.1 ml and CZ veterinaria-0.3 g/ml). Ovine chlamydiosis is a bacterial disease acquired from infected sheep or goats. Consequently ~100 million dollars would be required for compensation and slaughter of uninfected cattle diagnosed as false positives.
