title: Detection of antibody in rams with contagious epididymitis, using the enzyme-linked immunosorbent assay.
abstract: An enzyme-linked immunosorbent assay, using whole-cell and sonicated antigens prepared from Brucella ovis, Actinobacillus seminis, and Actinobacillus seminis-like cultures isolated from rams in Wyoming, was able to detect antibody to these antigens in rams with epididymitis. The whole-cell antigens used in this procedure gave lower background values, compared with those of the sonicated antigens. The procedure was able to detect antibody in rams before clinical signs of epididymitis became apparent.
