Gw. Horner et Dm. Orr, AN ENZYME-LINKED-IMMUNOSORBENT-ASSAY FOR DETECTION OF ANTIBODIES AGAINST BOVINE PESTIVIRUS, New Zealand Veterinary Journal, 41(3), 1993, pp. 123-125
A competitive enzyme-linked immunosorbent assay was developed and comp
ared with the serum neutralisation test for bovine pestivirus using 50
8 cattle sera and serial serum samples from a goat hyperimmunised with
five bovine pestivirus isolates. There was 96.7% agreement between th
e two tests. The relative sensitivity of the enzyme-linked immunosorbe
nt assay compared to the serum neutralisation test was 95.2% and the r
elative specificity was 99.4%. The titres of individual animals in the
assay did not show a close correlation with serum neutralisation test
titres. This may be because the antibodies measured in the two tests
are directed against different viral proteins. The enzyme-linked immun
osorbent assay has the advantage of being quicker and cheaper than the
serum neutralisation test. The configuration used in the FLISA means
sera from all species can be tested for pestivirus antibody using the
same set of reagents.
