Aim: To develop emerging diagnostic technique for bovine tuberculosis and to identify its potential risk factors.
Materials & Methods: Bacterial genomic DNA was isolated from bovine milk and human sputum samples and subjected to PCR using specific primer pairs. PCR results were validated using bacteriological cultures.
Results: PCR amplification of the targeted DNA fragment of Mycobacterium bovis was successful in 12.33% (37/300) of the bovine samples. Interestingly, 500-bp DNA fragment was also amplified in 6.67% (6/90) of the sputum indicating the possibility of zoonotic transmission. Rearing of livestock in household, unpasteurized milk consumption and smoking were identified as potential risk factors.
Conclusion: Results of the study may add value to bovine tuberculosis eradication campaigns to achieve the One Health initiative.

There is currently no commercial vaccine available against bovine tuberculosis (bTB). Mycobacterium bovis is the primary causative agent of bTB and is closely related to Mycobacterium tuberculosis, the pathogen responsible for human TB. Despite their limitations, mouse models are invaluable in early vaccine development due to their genetic diversity, cost-effectiveness, and the availability of research tools.

This study investigated the genetics of bovine tuberculosis (bTB) infectivity in Holstein-Friesian dairy cows using British national data. The analyses included cows with recorded sires from herds affected by bTB outbreaks between 2000 and 2022. Animals were considered bTB-positive if they reacted positively to the skin test and/or had positive post-mortem findings.

() is the primary agent of bovine tuberculosis (TB) in Mediterranean buffalo, which has a negative economic impact on buffalo herds. Improving TB diagnostic performance in this species represents a key step to eradicate efficiently this disease. We have recently shown the utility of the IFN-γ assay in the diagnosis of infection in Mediterranean buffaloes (), but other cytokines might be useful immunological biomarkers of this infection.

Tuberculosis is a zoonotic chronic respiratory infectious disease caused by the complex. The outbreak and epidemic of tuberculosis can seriously threaten human and veterinary health. To investigate the effects of environmental factors on tuberculosis in domestic ruminants, we collected data regarding the prevalence of tuberculosis in cattle, buffaloes, sheep, and goats in China (1956-2024) from publicly published literature and available databases.
