Abstract: SPA labeling technique for the gold-labled pond, BP26 purified by affinity chromatography for the detection antigen(T line), the colloidal gold test strip was designed to detect Brucellosis antibody, to discern infected mouse by Brucella abortus S19 and vaccinated mouse by BP26 KO Brucella strain YZ-2. There was no cross-reaction between the Brucella and the bacteria which have highly homology to Brucella for the strip test. Compared to other general tests, the sensitivity of the strip test is more than RBPT, and similar to ELISA; the coincidence of test results with ELISA was 100%, and the strip test was obviously more convenient. The colloidal gold test strip have the potential application to discern infected and vaccinated animals by Brucella.
