Value of Agglutination-Test. - Der Wert der Agglutinations Methode bei der weissen Ruhr. Dr. Sachweh, München. Berliner Tierärztliche Wochenschrift, 1931, p. 845.
A number of chickens were subjected, every three months, to the agglutination test. During this test it appeared that the agglutination titer varied considerably. All animals, of which a great number reacted positively at the beginning of the test, reacted negatively at the end thereof. This made it possible to comprehend the strongly varying results of the different tests. A group of 400 positive reacting hens gave healthy chicks. The wide advertising of the rapid blood test results in the poultry farmers making their own researches, and owing to the varying results obtained, it forces them to attach no value thereto.
