Enzyme-immunoassays using lipopolysaccharide as antigen were developed for the detection of bovine IgG1, IgG2 or IgA Brucella antibodies (Ab) in milk. The results of these tests were compared with those of the milk ring test (MRT) by analyzing 3212 bulk milk samples from farms located in regions where brucellosis is prevalent.

Five herds became infected during the study and were detected by ELISA 15 days to 6 months prior to detection by MRT. T…
