摘要: A study was carried out to compare the performance of enzyme-linked immunosorbent assay (ELISA) and blood polymerase chain reaction (PCR) for diagnosis paratuberculosis in cattle sheep. For cattle, a set 278 samples from 1 paratuberculosis-affected Friesian farm used; it included 80 ELISA-positive 198 ELISA-negative an age-matched group. Ninety-four were heifers 184 2–5-year-old cows. The overall analysis showed clear association (Fisher exact test [FET] P = 0.0049) but weak negative agreement (45.3%, kappa −0.1665 ± 0.0994) between 2 tests. It reflected moderate among (87.7%, 0.4471 0.2435) disagreement cows (62.7%, −0.3670 0.1057). sheep, 496 53 Latxa dairy flocks 180 dam/offspring pairs. tests on ovine strong (FET, 0.0005), whereas l...
