In order to identify different smooth Brucella strains, we prepared the monospecific serum against B.abortus O-chain A epitope and B.melitensis O-chain M epitope. Hyperimmune serum was collected from five rabbits, which were inoculated with heat-inactivated B.abortus (2308 strain) and heat-inactivated B.melitensis (16M strain) respectively. The hyperimmune serum was treated by serum antigen cross-absorption to get mono-specific antiserum. Monospecific serum against B. abortus O-chain A epitopes were obtained which at a 1/320 dilution agglutinated the homologous antigen and at a 1/2. 5 dilution did not agglutinated the the heterologous antigen. Monospecific serum against B. melitensis O-chain M epitopes were obtained which at a 1/160 dilution agglutinated the homologous antigen and at a 1/2.5 dilution did not agglutinated the the heterologous antigen. Then the monospecific serum was lyophilized and stored at-20℃. The slide agglutination test showed that monospecific serum against B. abortus O-chain A epitope and B. melitensis O-chain M epitope had no agglutination with homologous antigen. The results showed that the obtained monospecific serum were of high specificity and high titer, which could assist the identification of smooth Brucella species.
