| Forty-four cows from five herds infected with tuberculosis (TB) and without paratuberculosis (PTB), and 21 cows from a herd without either infection were studied. The cattle presented concordant results in both the skin test and gamma-interferon assay for TB and two commercial ELISAs for PTB. Animals were divided according to TB test results into Group A with 28 TB-infected animals, Group B with 16 TB-negative animals from infected herds, and Group C with 21 TB-negative cows from a tuberculosis-free herd (which were used as controls). Twenty of 28 animals from Group A (71.4%), 6/16 from Group B (37.5%) and none from Group C were reactive to PTB ELISAs, suggesting that these commercial kits were unable to distinguish between PTB and TB. It is proposed that... |
