Prevalence and risk factors of bovine tuberculosis in dairy cattle, 2020-2025: A systematic review and meta-analysis of available literature.
Clinical evidence update from Preventive veterinary medicine
Clinical Context
Peer-reviewed veterinary literature continues to shape everyday decision-making for production animal practice, especially when new evidence clarifies diagnosis, treatment selection, monitoring, or clinical outcomes.
What the Study Evaluated
A study published in Preventive veterinary medicine in 2026 evaluated prevalence and risk factors of bovine tuberculosis in dairy cattle, 2020-2025: A systematic review and meta-analysis of available literature..
Key Findings
Bovine tuberculosis (bTB) is a zoonotic disease caused by members of the Mycobacterium tuberculosis complex (MTBC), with Mycobacterium bovis being the primary agent responsible for infections in cattle, posing a significant threat to the global dairy industry. Although the COVID-19 pandemic during the 2020-2025 period may have disrupted its epidemiology, a comprehensive global meta-analysis of bTB prevalence and risk factors in dairy cattle for this period is currently lacking. We conducted an extensive literature search across multiple databases, including CNKI, PubMed, ScienceDirect, VIP, and Wan Fang. A total of 4783 records were...
Why It Matters for Veterinary Professionals
For veterinary professionals, the practical value of this work lies in how the findings may support more structured clinical assessment, clearer monitoring, and more informed decisions for production animal practice.
Practical Interpretation
The results should be interpreted in the context of the study design, population, inclusion criteria, and clinical setting. Application in practice should consider patient-specific risk factors, available diagnostics, local standards of care, and clinician judgment.
Clinical Takeaway
Overall, the study adds useful evidence for clinicians seeking to align daily practice with current veterinary research while maintaining a balanced, case-by-case approach.
