Abstract:
Standard agglutination test (SAT), enzyme-linked immunosorbent assay (ELISA), dot immunobinding assay (DIBA) have been developed for the detection of antibodies against 6 strains of Brucella and that against Yersinia enterocolitica Serotype O: g. The results showed that differentiation could be made between Brucella and Yersinia O: 9 when 16M SPA, OMP and YO: 3 SPA. OMP were used by ELISA, but not when 104M and YO: 9 antigens were used by SAT. So, 16M and YO: 3 OMP antigens were better for detection of antibodies against Brucella and Yersinia O: 9 by ELISA.
