Reliability of an ELISA for the diagnosis of bovine paratuberculosis DIAGNOSIS ofMycobacterium avium subspecies paratuberculosis (MAP) infected cattle is challenging, due to the limited sensitivity and imperfect specificity of available tests. In a cross-sectional observational study, 3757 adult dairy cattle from 11 Colorado herds were tested twice each, at intervals of 77 to 600 days, with a commerical ELISA (Idexx Laboratories). Many cows changed ELISA status over the course of the study. Overall, 60-5 per cent of cows that were positive on the initial sample were positive on the second sample; 23*6 per cent fell into the test-suspect category; and 15-9 per cent were negative on the second sample. Of 408 cows that were initially classed as test-suspect, 32-8 per cent maintained their suspect status for the second sample while 23*0 per cent became positive and 44-1 per cent became negative. Unfortunately, it was not possible to confirm the infection status of these cows. However, the study confirms the non-repeatability of ELISA results when the same cow is retested at a later date.
