Harmonisation of European tests for serological diagnosis of Brucella infection in bovines
|Author(s) :||.A. McGiven, J.A. Stack, L.L. Perrett et.al|
The principal methods for the serological diagnosis of bovine brucellosis are the complement fixation test (CFT), serum agglutination test (SAT), Rose-Bengal test (RBT), indirect enzyme-linked immunosorbent assay (iELISA) and more recently the competitive ELISA (cELISA) and the fluorescent polarisation assay (FPA). Guidelines set by the World Organisation for Animal Health (OIE) describe methods and diagnostic thresholds for each of these tests. Many countries have adopted these methods for the purposes of eradication of brucellosis and have legislated for the use of these tests (the CFT and SAT in particular) for the prevention of the spread of the disease through international trade. Within the European Union (EU) each member state has a National Reference Laboratory which regulates the quality of brucellosis diagnosis and works to the recommendations set by the OIE. This article describes the results from the first three EU ring trials assessing the harmonisation of diagnostic tests between each member state.
