Abstract
Mycobacterium bovis was isolated from respiratory secretions and lymph nodes from 15 skin test-negative cattle which exhibited interferon-gamma responses. These field cases, identified by blood testing, constituted a significant proportion of skin test-negative cattle which had been subjected to extensive post mortem examinations. Typical tuberculous lesions were found in seven of them. The consequences of cattle with early tuberculosis infection not being detected by traditional tuberculin testing are considered.Entities:
