title: [Experience with simple ELISA test systems for Brucella serology in cattle, sheep and goats].
abstract: The objective of this work was to use the ELISA technique for the serological surveillance for freedom of brucellosis of cattle, sheep and goats. By comparing 28 cattle sera taken after a brucellosis outbreak, 15 bovine sera supplied by the Federal Institute for Health Protection of Consumers and Veterinary Medicine (BgVV) and 497 serum slow agglutination test (SSAT) and complement fixation test (CFT) negative bovine sera from herds officially declared free of brucellosis, the ELISA technique not only shows higher sensitivity as compared to SSAT and CFT but also distinguishes clearly between positive and negative reactions. The serological comparison by SSAT, CFT and ELISA of 615 cattle, 624 sheep and 630 goat sera from herds acknowledged as brucellosis free showed equivalent specificities for both CFT and ELISA. The specificity of the SSAT was much lower, 81.1% in cattle and 96.2% in goat sera. The examination of 5796 cattle, 1337 calf, 5031 sheep and 1796 goat sera demonstrates the advantage of the ELISA technique as routine method. The possible application of the ELISA technique as a screening method for serological brucellosis tests in sheep, goats and possibly also in pigs is discussed.
