Antibodies to Brucella spp. in Pacific bottlenose dolphins from the Solomon Islands.

Brucella spp. have been recently isolated from a variety of marine mammals. Serum samples from 58 Pacific bottlenose dolphins (Tursipa aduncus) from the Solomon Islands were tested for antibodies to Brucella spp. by the tube agglutination test (TAT), enzymed-linked immunosorbent assay (ELISA), and immunoblotting. Anti-Brucella spp. antibodies were detected by TAT and ELISA in 31 and 40 of 58 samples, respectively. These results suggest that Pacific bottlenose dolphins from the Solomon Islands are infected with Brucella spp. or a Brucella-like organism.
