Abstract: Investigations were carried out on caprine brucellosis in a costal area in Egypt. A total number of 577 Baladi Does was examined for Brucella infection using different serological tests. Specimens were taken from seropositive obligatory slaughtered Does (No = 33) for Brucella isolation, histopathological examination, Polymerase Chain Reaction (PCR) assay and determination of serum copper (Cu), zinc(Zn) and iron (Fe) concentrations. Results indicated that the incidence of brucellosis was 3.0-5.0%, by using the different serological tests. Buffered Acidified Plate Antigen Test (BAPAT) is of the highest sensitivity followed by Rose Bengal Plate Test (RBPT), L-ELISA, Complement Fixation Test (CFT), P-ELISA, Rivanol test (RVT) and Tube Agglutination Test (TAT). In seropostive Does, Brucella melitensis biovar 3 was isolated from 78.78% and PCR yielded expected products in 81.81%. Moreover, granulomatous endometritis, lymphocytic mastitis and lymphoid depletion in both lymph nodes and spleen were evident together with significant (p<0.001) decreases in serum Cu, Zn and Fe concentrations. In conclusion, more attention should be paid to goat in brucellosis epidemiology in the application of national program of brucella control and eradication.
