Fifteen metacestode antigens from Taenia saginata were defined by Laurell crossed immunoelectrophoresis and investigated for their potential use in immunodiagnosis of bovine cysticercosis. Several antigens cross reacted with those of some common cattle parasites. Three of the antigens, designated as numbers 4, 8 and 11, were selected on the basis of their restricted cross reactions and were isolated by affinity chromatography. These antigens showed high sensitivity and specificity values in the enzyme-linked immunosorbent assay (Elisa) for serodiagnosis of bovine cysticercosis.
