| Abstract: | A phenol fraction, capable of adsorbing cross-reacting antibodies from Y. enterocolitica O9 antiserum without affecting its serological activity against specific antigens, has been obtained from a Brucella strain. The physicochemical and antigenic characteristics of the preparation are presented. It is recommended that the proposed method be tested in differentiation of intestinal yersiniosis caused by Y. enterocolitica O9 from Brucella infection. This work has resulted in obtaining highly specific antiserum to Y. enterocolitica, serovar O9. |
