Abstract
Summary
The preparation of a rapid antigen for use in the agglutination reaction for the diagnosis of Brucella infection is described. The essential difference between this antigen and former preparations is the growth of the organism on collodion membranes layered over nutrient agar.
When compared with regular rapid antigen, the collodion membrane rapid antigen showed markedly less sensitivity in serum dilutions of 1: 100 or less. The collodion membrane rapid antigen and test tube antigen were more frequently in agreement than test tube antigen and regular rapid antigen.
