What percentage is the expected response rate for the Caudal Fold Test (CFT) in bovine tuberculosis?

• A. 10-15%
• B. 5-10%
• C. 1-5%
• D. 15-20%

Answer: (C)

The expected response rate for the Caudal Fold Test (CFT) in detecting bovine tuberculosis is indeed in the range of 1-5%. This percentage reflects the sensitivity of the test in detecting the disease among cattle populations. The CFT is a diagnostic method used to identify animals that might be infected with Mycobacterium bovis, the causative agent of bovine tuberculosis. This relatively low response rate can be attributed to several factors, including the test's specificity and the prevalence of the disease within the population being tested. In regions with low incidence rates of bovine tuberculosis, even a well-conducted test may yield a limited number of positive results, signifying that the disease is not widespread. Consequently, this understanding helps inform veterinary practitioners and animal health officials about the limitations and expected outcomes of using the Caudal Fold Test as part of a broader surveillance strategy for controlling and managing bovine tuberculosis in cattle herds.
