Defatting milk for the Brucella abortus whey agglutination test with chloroform caused some reduction in the titre in i.u./ml. in 42 of 57 samples and this reduction exceeded 50% in seven. Though this procedure will probably rarely affect the final interpretation of the test defatting the milk by centrifugation is preferred.
