The use of EDTA in the microtitration serum agglutination test in bovine brucellosis

Abstract

The use of EDTA in the microtitration serum agglutination test reduced the incidence of low-titre agglutinations in sera with titres < 30 international units per ml in the complement fixation test, while not affecting agglutinations in sera with titres ≥ 30 international units per ml in the complement fixation test.
